The Best Motorcycle Armored Base Layers

An armored base layer is impact protection with no abrasion protection, and knowing that changes what you should buy. Five armored shirts, protection jackets and vests ranked on the EN 1621 clause each maker publishes for every pad, then on the zones covered, then on whether the garment itself is certified at all.

By Stephen V.Last verified How we compare

There are two reasons riders buy an armored base layer, and they lead to different products. The first is that the jacket you own came with shoulder and elbow pads and an empty pocket where the back protector was supposed to go, and you want to fill that gap. The second is that it is ninety-five degrees, you are not putting a textile jacket on, and you still want something between you and the road. A shirt with armor sewn into it solves both — but only one of them completely.

Here is the sentence that should sit at the top of every page about this category, and rarely does: an armored base layer protects you from impact, not from sliding.That is not a criticism, it is the design. Europe has a garment standard, EN 17092, and its lightest class exists specifically for this kind of product. As the test house SATRA states it, “Class C garments are designed to provide impact protection for areas covered by the impact protector(s) only, and they do not offer minimum abrasion protection.” Class C is the honest label for an armored shirt. It is also the label almost nobody in this category bothers to earn: of the five products below, exactly one publishes an EN 17092 class.

So this ranking is built on four criteria, in this order. First, what the maker publishes about EN 1621— the armor standard, split by body part into EN 1621-1 for limbs, EN 1621-2 for the back and EN 1621-3 for the chest — because “CE Level 2” with no clause attached is a marketing line, not a certification. Second, which zones actually have a pad in them, since two products with identical levels can protect completely different parts of you. Third, whether the garment itself carries an EN 17092 class, because that tells you whether it is a certified piece of clothing or a harness for protectors. Fourth, ventilation, weight and fit, on the same logic as every other page here: the layer you leave in the garage protects nothing.

We have not crash-tested any of these and we own none of them — here is exactly how we compare gear instead. Every spec below was read from the manufacturer’s own page on the date recorded with each product. Prices in the text stay qualitative; the live number sits on each buy button.

Klim Tactical Pro Armored Shirt

The only pick here whose garment is certified as well as its armor: Klim states a CE CU rating to EN 17092-6 on top of Level 2 chest and back pads and a Level 1 shoulder. That combination — plus a cooling four-way-stretch chassis you can wear as your outer layer in August — is what an armored base layer is supposed to be.

#1Best overallOur score8.9

Klim Tactical Pro Armored Shirt

The only pick here whose garment is certified as well as its armor: Klim states a CE CU rating to EN 17092-6 on top of Level 2 chest and back pads and a Level 1 shoulder. That combination — plus a cooling four-way-stretch chassis you can wear as your outer layer in August — is what an armored base layer is supposed to be.

Strengths

  • Klim publishes the clause for every pad: Rogue CE Level 2 chest, Level 2 back and Level 1 shoulder
  • The only shirt here with a stated garment certification — "CE CU rating certified to EN 17092-6", the Class C impact-protector ensemble
  • Aggressor cooling fabric with brrrº mineral treatment and a moisture-wicking mesh chassis, so it works as a standalone summer layer
  • Armor is removable and the shirt is washable with the pads out
  • Soft rib protection in addition to the compression-molded panels

Trade-offs

  • Short sleeve, so there is no elbow armor — Klim's long-sleeve version adds a Level 1 elbow pad but is not sold on Amazon
  • Five sizes only (MD to 3X), with nothing below medium
  • Klim publishes no weight for this shirt anywhere we could fetch
  • Class C means the garment holds protectors — it is not abrasion-rated, so it does not replace a jacket
Armor certificationKlim Rogue CE Level 1 shoulder pad; Rogue CE Level 2 chest pad; Rogue CE Level 2 back pad (removable)
Zones protectedChest, back and shoulders; soft padding at the ribs
Garment classClass C — "CE CU rating certified to EN 17092-6" (no abrasion requirement)
Material4-way-stretch Klim Aggressor cooling fabric with brrrº technology over a moisture-wicking antimicrobial mesh chassis

#2Best coverage for the moneyOur score8.7

Alpinestars Bionic Plus V2

The widest certified coverage on this page for the least money. Alpinestars prints all three clauses — EN 1621-1:2012 Level 1 at elbows and shoulders, EN 1621-2:2014 Level 2 at the back, EN 1621-3:2018 Level 2 at the chest — which means it is the cheapest way here to put a certified protector on four zones at once.

Strengths

  • Four zones with the clause and level printed for each: elbow and shoulder Level 1, back Level 2, chest Level 2
  • Perforated Cell Technology chest protector and a back protector with a flexion channel, so the coverage does not cost all your mobility
  • Compatible with Alpinestars' Bionic Neck Support, which matters if you also ride off-road
  • Five adult sizes, S to 2XL, with adjustable shoulder straps and a padded chassis

Trade-offs

  • It is a protection jacket, not a shirt — there is no fabric to speak of and no EN 17092 garment class at all
  • Alpinestars publishes no weight for it on the product page
  • Cut and marketed for off-road use, so it is bulkier under a close-fitting road jacket than a vest would be
  • Elbow and shoulder armor is Level 1, a step below the Level 2 at the chest and back
Armor certificationEN 1621-1:2012 Level 1 elbow and shoulders; EN 1621-2:2014 Level 2 back; EN 1621-3:2018 Level 2 chest

#3Best for adventure and off-roadOur score8.6

Leatt 3DF AirFit Evo

The most thoroughly documented protector here and the only one whose maker publishes a weight. Leatt states chest EN 1621-3 Level 2, back EN 1621-2 Level 2 and elbow and shoulder EN 1621-1 Level 1, adds French Motorcycle Federation certification, and prints "from 1.53 kg" instead of leaving you to guess.

Strengths

  • Every zone published with its clause and level: chest Level 2, back Level 2, elbow and shoulder Level 1
  • The only product on this page with a published weight — "from 1.53 kg"
  • 3DF AirFit multi-impact foam with ventilated mesh in the high-heat areas, plus anti-odor MoistureCool and AirMesh fabrics
  • BraceOn fitting system for a Leatt neck brace, and separate FFM (French Motorcycle Federation) certification
  • Solid chest plate with a side-entry zip — genuine roost protection, not just impact foam

Trade-offs

  • The most expensive pick here, by a clear margin
  • Three size brackets only (S/M, L/XL, XXL), sized by rider height rather than chest measurement
  • A hard chest plate designed for roost is bulk you do not need on a road bike, and it is warm under a textile jacket
  • No EN 17092 garment class — it is a protector, so there is no abrasion rating to have

#4Best slim layer under a jacketOur score8.4

Alpinestars Nucleon Flex Pro Vest

The slimmest way to get Level 2 on both the spine and the chest, and the only pick that publishes the temperature qualification: Alpinestars states EN 1621-2:2014 Level 2 back and EN 1621-3:2018 Level 2 chest, each marked T+ and T-, meaning the pads held their level when tested hot and cold rather than only at room temperature.

Strengths

  • Level 2 at both the back and the chest — the only pick here where every certified zone is Level 2
  • T+ and T- marking on both protectors: the level was met in high and low temperature testing, not just ambient
  • Divided chest protectors are removable, so it can be run as a back-protector vest alone
  • Soft-touch perforated mesh chassis with an adjustable elasticated waistband, cut to disappear under a jacket
  • Runs from XS, the smallest size range on this page

Trade-offs

  • No shoulder or elbow armor at all — those zones are left to whatever is in your jacket
  • Alpinestars publishes no weight for it
  • No EN 17092 garment class, so it adds nothing to abrasion protection
  • XS-XL only: no 2XL, unlike the Bionic Plus V2

#5Best budgetOur score7.2

Wicked Stock Potomac Armored Shirt

Armor on three zones for roughly a quarter of what the Klim costs, and the widest size run here by a distance. It is ranked last for one reason and we would rather say it than bury it: Wicked Stock states "CE Level 2" for the shoulder, elbow and back pads but never names the EN clause behind that number, and publishes no garment class at all.

Strengths

  • Removable armor at the shoulders, elbows and back — three zones, including the two the Nucleon vest leaves out
  • XS through 5XL, a 28-60 inch chest range that no other pick here comes close to
  • Mesh panels through the chest, back and arms with stretch fabric between, so it works as a hot-weather layer
  • Full-length front zipper and armor that pulls out for washing

Trade-offs

  • "CE Level 2" is stated without the EN clause behind it — no EN 1621-1 for the limb pads, no EN 1621-2 for the back
  • No EN 17092 garment class published, so there is no certified abrasion claim of any kind
  • The maker's own page carries the level inconsistently: the URL says Level 1, the title and body copy say Level 2
  • The Amazon listing does not print the Potomac model name, so match it by the description rather than the title
  • No published weight and no chest protector
Armor certificationRemovable shoulder, elbow and back pads stated as "CE Level 2"; no EN 1621 clause published for any of them

How we ranked these

EN 1621 is three standards, not one, and the clause tells you which body part was tested.EN 1621-1 covers limb protectors — shoulders, elbows, knees, hips. EN 1621-2 covers back protectors. EN 1621-3 covers chest protectors. Each one has a Level 1 and a Level 2, where Level 2 transmits less force in the test and is the higher rating. The useful consequence is that a complete claim always names a clause and a level for each zone: “EN 1621-2:2014 Level 2 back” is a claim you can check, and “CE Level 2 armor” on its own is not. Alpinestars, Klim and Leatt all publish the full string for every pad. Our CE armor and garment ratings guide walks through what the levels mean in plain English if this is new to you.

Then the zone list, because the level says nothing about where the pads are.This is where the five products separate hardest. The Alpinestars Bionic Plus V2 and the Leatt 3DF AirFit Evo both cover four zones — chest, back, shoulders and elbows. The Klim Tactical Pro covers three, dropping the elbow because it is a short-sleeve shirt. The Alpinestars Nucleon Flex Pro covers two, back and chest, and nothing on the arms at all. The Wicked Stock covers shoulders, elbows and back but has no chest protector. There is no single “most coverage” winner that is right for everyone: if your jacket already has shoulder and elbow pads, buying them a second time is money spent on bulk, and the two-zone vest is the smarter purchase.

Then the garment class, which is the finding on this page.Only the Klim publishes one: it states a “CE CU rating certified to EN 17092-6”, which is Class C. That is worth understanding precisely, because it cuts both ways. It is a real certification, tested and marked, and it is more than any other product here can show. It also carries no abrasion requirement whatsoever. A Class C garment is defined as one intended to be worn with and supplement a Class AAA, AA, A or B garment — in other words, alongside a jacket, not instead of one. The other four publish no class at all, which for the three pure protectors is not a criticism (a protector is not a garment and has nothing to certify), but for the Wicked Stock shirt, which is sold as clothing, is a real gap.

Then ventilation, weight and fit.Almost nobody in this category publishes a weight: Leatt states “from 1.53 kg” and the other four state nothing, which is why the weight row on four of the five spec tables below reads “Not published.” What makers do publish is airflow, and it matters more here than on any other piece of gear, because this layer sits directly against your skin under everything else. Klim’s cooling stretch fabric, Alpinestars’ perforated Cell protectors and Leatt’s ventilated 3DF foam are all attempts at the same problem. Size range is the other practical filter and it varies wildly: the Wicked Stock runs XS to 5XL, the Klim starts at medium, and the Leatt is sold in three brackets keyed to rider height rather than chest measurement.

Shirt, protection jacket or vest — which one do you need?

Buy the armored shirt if heat is the reason you are shopping. The Klim Tactical Pro is our top pick because it is the only product here that is genuinely both things at once: a certified set of protectors and a certified garment you can wear as your outer layer on a hot day. Level 2 at the chest and back, Level 1 at the shoulder, all with the clause published, in a four-way-stretch cooling fabric that Klim designed to sit against skin. The honest costs are that the short sleeve means no elbow armor, that it starts at medium, and that it is the most expensive shirt on this page by a wide margin. Klim does make a long-sleeve version that adds a Level 1 elbow pad, but it is not stocked at the retailer our buy links point to, so we have not ranked it.

Buy the protection jacket if you want the most certified zones for the least money. The Alpinestars Bionic Plus V2puts a published protector on four zones — Level 1 elbow and shoulder, Level 2 back, Level 2 chest — for less than the Leatt and less than the Klim shirt. It is not clothing and does not pretend to be: it is a padded chassis with protectors strapped to it, worn under a jacket or a jersey. It is cut for off-road use, so it is bulkier under a close road jacket than a vest, and Alpinestars publishes no weight for it. If your existing jacket is a mesh summer shell with token pads, this is the cheapest way to fix all four upper-body zones at once.

Buy the vest if your jacket already has arm armor. This is the most common real situation and the most commonly over-bought. Almost every certified jacket ships with shoulder and elbow protectors and leaves the back and chest empty. The Alpinestars Nucleon Flex Pro fills exactly that gap and nothing else, and it is the only pick here where every certified zone is Level 2. It also publishes something none of the others do: both protectors are marked T+ and T-, meaning they met their level when tested hot and cold rather than only at room temperature, which is the difference between armor that works in August traffic and armor that was only ever measured in a lab at 23 degrees. Its chest protectors come out, so it can be run as a back-protector vest alone.

Buy the off-road protector if the hazard is roost as well as impact. The Leatt 3DF AirFit Evo is the most thoroughly documented product on this page: four zones with the clause and level printed for each, a separate French Motorcycle Federation certification, a BraceOn fitting system so a neck brace sits correctly over it, and the only published weight in the category. It also has a solid chest plate, which is protection against flying rocks that a road rider has no use for and will notice as heat and bulk. It is the priciest pick here and it is sized in three brackets by rider height. If adventure riding is the use case, our adventure helmet roundup covers the other end of the same kit.

Buy the budget shirt with your eyes open. The Wicked Stock Potomacputs removable pads on shoulders, elbows and back for roughly a quarter of the Klim’s price, in a size run from XS to 5XL that nothing else here approaches. We rank it last and we will say why rather than bury it in a footnote: Wicked Stock states “CE Level 2” for those pads but never names the EN clause behind the number, publishes no EN 17092 garment class, and prints the level inconsistently on its own site — the product URL says Level 1 while the title and body copy say Level 2. It is still armor where you previously had none, which is a real improvement over a t-shirt. It is not a certified equivalent to the four above it, and pretending otherwise would be the easiest way for this page to be wrong.

What an armored base layer does not do

The single most expensive mistake in this category is treating an armored shirt as a jacket replacement. Impact protection and abrasion protection are two different jobs tested by two different standards, and armor does nothing for the second one. In a slide, the fabric between you and the asphalt is what matters, and Class C fabric has no minimum requirement to meet — it only has to hold the protectors in place. That is why EN 17092 defines Class C as a garment to be worn with a Class AAA, AA, A or B garment. It is a supplement by design.

There is a version of this that is fine and a version that is not. Wearing an armored shirt under a mesh jacket, or under a leather jacket that has no armor pockets, is exactly what the product is for. Wearing an armored shirt and jeans on a summer ride because the armor makes it feel covered is the mistake — you have upgraded the impact protection on three or four zones and left your skin completely unprotected. If that is the ride you actually take, the honest fix is a Class A mesh jacket, which is certified for abrasion and flows nearly as much air; our jackets roundup ranks those. The lower half has the same problem and the same answer in our riding pants and Kevlar jeans roundup.

The second thing a base layer does not do is fire. If you are here because you want the biggest possible upgrade to torso protection, the honest answer is that a passive back and chest protector is not it — an airbag vest is, because it acts during the crash rather than after you land. It also costs three to five times as much. The two are not mutually exclusive, and several airbag systems include a passive back protector as well, but if the budget only covers one, buy the one that matches your riding.

Armored hoodies, flannels and “armor-ready” shirts

Search for an armored base layer and you will land on a large number of armored hoodies and riding flannels, and they are a genuinely different purchase for two reasons. First, they are outer garments, not base layers: a hoodie with aramid lining is trying to be a light jacket, and it should be judged on the same EN 17092 abrasion class as a jacket, not on Class C. Second, and more importantly — a great many of them are sold as “armored” when what they actually have is empty pockets for optional armorthat is not in the box. Read the listing carefully. If the phrase is “pockets for CE-rated armor,” you are buying a shirt and then buying pads separately, which can still be a sensible purchase — but it is not the same product as a shirt with certified protectors already fitted, and the price difference usually reflects exactly that.

The same caution applies to the phrase “CE approved.” There is no such thing as a CE-approved motorcycle garment in the sense the phrase implies. There are protectors certified to a clause of EN 1621 at a stated level, and there are garments certified to a class of EN 17092. Anything vaguer than that is a claim nobody has to stand behind, and we mark it “Not published” in the spec tables above rather than assume the best case.

What we left out, and why

Excellent protectors that are not sold at the retailer we link.Forcefield Body Armour’s Pro Shirt and Knox’s Urbane Pro are the two products most often recommended in this category by riders, and neither has a stocked listing at the retailer our buy links point to — a search for either returns unrelated products. Klim’s own long-sleeve Tactical Pro, which adds the Level 1 elbow pad the short-sleeve version lacks, is in the same position: it exists, it is better specified than our top pick, and you would have to buy it direct. They are named here on purpose. If one of them fits you better, buy it.

Roost deflectors sold as body armor.A large slice of the off-road “chest protector” market is built to stop flying stones and is not certified as impact protection at all. Those products are good at the job they were designed for, and buying one expecting an EN 1621-3 chest protector is a straightforward mistake. We only ranked protectors whose makers publish a clause and a level.

The rest of the sub-$100 marketplace shirts.Wicked Stock is here as the one budget pick because it is at least specific about the zones and the level, and because its size run genuinely serves riders the premium brands do not. The wider category — a long tail of near-identical mesh shirts claiming “CE Level 2” with no standard named anywhere on the listing or the maker’s site — is left out on the same rule we applied to uncertified airbag vests and uncertified riding pants: we do not rank a protection claim we cannot check against a standard. If you are assembling gear from scratch, the ATGATT first-gear checklist puts a helmet, gloves and a certified jacket ahead of any of this, and it is right to.

Frequently asked questions

Does an armored base layer replace a motorcycle jacket?

No, and this is the most important thing to understand before you buy one. Armor and abrasion resistance are tested by two different standards. EN 1621 rates the protectors for impact; EN 17092 rates the garment for abrasion. The lightest EN 17092 class, Class C, is the one written for armored base layers, and as SATRA states it, Class C garments provide impact protection only for the areas the protectors cover and do not offer minimum abrasion protection. The standard explicitly defines them as garments to be worn with a Class AAA, AA, A or B garment. Wear an armored shirt under a jacket, or under a jacket that has no armor pockets of its own — not instead of one.

What is the difference between EN 1621-1, EN 1621-2 and EN 1621-3?

They are the same standard split by body part. EN 1621-1 covers limb protectors — shoulders, elbows, knees and hips. EN 1621-2 covers back protectors. EN 1621-3 covers chest protectors. Each has a Level 1 and a Level 2, with Level 2 transmitting less force in the test. A complete claim names the clause and the level for each zone, which is why a spec that says only "CE Level 2 armor" is worth less than it looks: it tells you nothing about which body part was tested, or against which requirement.

Do I need a chest protector, or is a back protector enough?

It depends on what your jacket already has and what you ride. Almost every certified jacket ships with shoulder and elbow armor and an empty back-protector pocket, so the back is the near-universal gap and the first thing to fill. A chest protector matters most for riders who are likely to go over the bars or into something — sport riders, off-road riders, and anyone riding fast on roads with hard furniture. If you only want to fix the back, buy a vest whose chest protectors are removable, which is what the Alpinestars Nucleon Flex Pro allows.

What does the T+ and T- marking on armor mean?

It records the temperatures the protector was tested at and still met its level. Standard EN 1621 testing happens at ambient temperature; the T+ and T- marks indicate that the same protector was also tested hot and cold and passed. It matters because armor is made of energy-absorbing foam whose behavior changes with temperature, and a pad that has been against your body in summer traffic is not at room temperature. On this page the Alpinestars Nucleon Flex Pro is the only pick whose maker publishes both marks.

Can you wear an armored base layer under any jacket?

Usually, but check the fit before you commit. A slim vest disappears under most jackets. A full protection jacket with a chest plate and shoulder pads adds real bulk, and a close-cut sport jacket may not have the room — the same problem riders hit with under-jacket airbag vests. If your jacket is already snug with its own armor in place, either size the jacket up or choose the slimmest layer that covers the zones you actually need.

Are the cheap CE Level 2 armored shirts on Amazon any good?

They are better than nothing and worse than they sound. The armor pads in them may well be certified, and a removable pad on your shoulder is a genuine improvement over a t-shirt. What is usually missing is the paperwork: no EN 1621 clause named for the pads, no EN 17092 garment class, and sometimes an inconsistent level printed across the maker's own pages. We rank exactly one of them here, last, and we say plainly what it does not publish. If the price gap is what is keeping you from any protection at all, buy one — just do not treat it as equivalent to a spec that names its standards.

Is an armored shirt or an airbag vest the bigger safety upgrade?

An airbag vest, comfortably — it is the only piece of road gear that acts during the crash rather than after you land, and it covers the torso zones where the serious injuries happen. It also costs several times as much, needs charging or a tether, and consumes a gas cartridge when it fires. A passive armored base layer is the cheaper, simpler, always-ready option, and it is the right first purchase for most riders. If your helmet, gloves and jacket are sorted and the budget is there, the airbag is the bigger step.
