Best Arc-Rated CAT 2 FR Clothing (2026): Garments That Actually Publish a Number

If you want arc-rated CAT 2 clothing you can actually buy today, my top pick is the Carhartt Force Men's 100235 FR long-sleeve T-shirt — its listing publishes a real ATPV of 8.9 cal/cm² (CAT 2), it's a comfortable all-shift knit, and it's in stock. But "best" depends on what you need: a shirt, pants, or full-body coverage, and whether you care about the highest stated number or the one you can order right now. FR clothing is fabric engineered to resist ignition, self-extinguish once the flame source is gone, and not melt onto your skin — it is not "fireproof." The one rule I held to across this whole guide: a garment only earns a spot if its listing actually states a cal/cm² figure of 8 or higher. No implied ratings, no borrowed numbers.

How I ranked these (protection first, not commission)

I ranked these on protection first, then value, then fit — not on what pays the most. Here's the discipline I held to: I only quote a spec when the product listing actually states it. Where a listing doesn't publish a fabric weight, an inherent-vs-treated note, or an explicit ASTM F1506 number, you'll see "not stated" or "—" rather than a guess. I never carry one model's cal/cm² number over to another, and I never imply an arc rating a listing doesn't print. For a CAT 2 guide that means every pick below has a stated ATPV of 8 cal/cm² or higher on its own page. Availability was a tiebreaker: a garment you can't order can't protect you, so two discontinued picks with higher published numbers still landed at the bottom.

1. Carhartt Force Men's 100235 FR Long-Sleeve T-Shirt — best for everyday in-stock wear

This is the one I'd put on most shifts. It's a 6.75 oz 100% cotton FR jersey knit, and its listing states an ATPV of 8.9 cal/cm² — a legitimate CAT 2 number on a shirt that wears like a normal long-sleeve tee. It's the most comfortable thing here for an all-day base or mid layer, and it's in stock at a fair price. The honest trade-off: it's a shirt, not full coverage, and the listing doesn't say whether the FR is inherent or treated — which matters for how the protection holds up over many washes.

• Pros: Stated 8.9 cal/cm² (CAT 2); soft cotton knit that's comfortable all shift; in stock; lowest price of the in-stock picks; listing notes NFPA 2112 / 70E compliance.
• Cons: Base/mid layer only, not full-body; inherent-vs-treated not stated; no explicit ASTM F1506 number cited; 100% cotton knit is less abrasion-tough than a twill.

2. Bulwark CLD4 Navy Coverall — best for full-body coverage you can buy

When you want one garment that covers torso, arms, and legs, this is my in-stock pick. It's a 6 oz 88/12 cotton-nylon blend, and the listing states an ATPV of 8.7 cal/cm² (it labels it HRC 2 / CAT 2). That arc rating applies across the whole coverall, not just a shirt, which is why I rank it above the button-up and the pants. The trade-off is comfort and detail: a coverall runs warmer than a shirt-and-pants combo in summer, the page lists ASTM as "Yes" without citing an explicit F1506 number, and it doesn't state inherent vs treated.

• Pros: Stated 8.7 cal/cm² (CAT 2 / HRC 2) over the whole garment; one-and-done coverage; durable 88/12 blend; in stock; listing notes NFPA 2112 / 70E.
• Cons: Warmer than separates in heat; no explicit F1506 number; inherent-vs-treated not stated; highest price of the in-stock picks.

3. Ariat 10013513 Plaid Twill Work Shirt — best for a button-up shirt

If you'd rather wear a button-up than a knit tee, this is the one. It's a 6.5 oz 88/12 cotton-nylon twill, and its listing states an ATPV of 8.9 cal/cm² (CAT 2) — the same headline number as my top pick, in a tougher woven fabric that looks like an ordinary work shirt. It's a strong choice for anyone who wants a collared, pocketed shirt over a knit base layer. The honest trade-off: it costs more than the Carhartt knit, twill feels stiffer on day one, and the listing doesn't cite an explicit F1506 figure or say inherent vs treated.

• Pros: Stated 8.9 cal/cm² (CAT 2); rugged 88/12 twill; looks like a normal work shirt; in stock; listing notes NFPA 2112 / 70E.
• Cons: Pricier than the Carhartt knit; twill is stiffer until broken in; no explicit F1506 number; inherent-vs-treated not stated.

4. MCR Safety PT2N FR Work Pants — best for completing the ensemble

This is the only pair of pants in the lineup that publishes an arc rating. It's a premium 88/12 cotton-nylon blend, and the listing states an ATPV of 8.6 cal/cm² (CAT 2), with a note that the garment is UL-certified and carries a lifetime FR guarantee. Pair it with a CAT 2 shirt above and you've got a full head-to-legs ensemble that breathes better than a single coverall in hot weather. The trade-off: the listing doesn't state fabric weight or an explicit F1506 number, and you do have to buy a matching FR top separately to actually be covered.

• Pros: Stated 8.6 cal/cm² (CAT 2); the only arc-rated pants here; UL-certified with a lifetime FR-guarantee note; cooler than a coverall when paired with a shirt; live and orderable.
• Cons: Pants only — needs a matching CAT 2 top; fabric weight not stated; no explicit F1506 number; inherent-vs-treated not stated.

5. Walls FRO56915 Light Blue Work Shirt — highest shirt number, but discontinued

On paper this has the strongest stated rating of any shirt here. It's a 7 oz 88/12 cotton-nylon (88% cotton, 12% high-tenacity nylon), and its listing states an ATPV of 9.6 cal/cm² — labeled HRC Level 2 / CAT 2. That's a genuinely high published number for a single shirt. The catch is simple and decisive: the page shows it as currently out of stock and discontinued by the manufacturer, with no price stated. I'm keeping it on the list for reference because the rating is legitimate, but I can't recommend buying something you can't reliably get.

• Pros: Highest stated shirt rating here at 9.6 cal/cm² (CAT 2); sturdy 7 oz 88/12 with high-tenacity nylon; listing notes NFPA 2112 / 70E.
• Cons: Out of stock / discontinued; no price stated; can't be reliably ordered; no explicit F1506 number; inherent-vs-treated not stated.

6. Bulwark CEB2OR Orange Coverall — highest stated number overall, but discontinued and treated

This coverall carries the biggest published figure in the guide. It's a 9 oz 100% cotton twill with an ammonia-cure FR finish, and its listing states an ATPV of 11.2 cal/cm² (CAL 8+ / CAT 2). Two honest caveats keep it at the bottom. First, it's a treated garment — the FR comes from a finish on cotton, not from the fiber itself, and treated FR can lose protection if it's laundered improperly over its life. Second, it's discontinued and out of stock, with no price, and this particular page doesn't even state NFPA 2112 or 70E. Reference only.

• Pros: Highest stated rating in this guide at 11.2 cal/cm² (CAT 2); heavyweight 9 oz cotton twill; full-body coverage.
• Cons: Discontinued / out of stock; treated (ammonia-cure) FR, not inherent; NFPA 2112 / 70E / F1506 not stated on this page; no price stated.

Why does a published cal/cm² number actually matter?

Because for arc-flash work, the cal/cm² figure is the whole point. Your site's arc-flash study assigns each task an incident-energy level, and your clothing has to meet or beat it. A garment can be perfectly flame-resistant and pass NFPA 2112's flash-fire test while never publishing an arc rating at all — those are two different hazards measured two different ways. If a listing only says "flame resistant" or "NFPA 2112" with no ATPV, you have no idea where it lands on the CAT scale, so you can't match it to a task. CAT 1 starts at 4 cal/cm², CAT 2 at 8, CAT 3 at 25, and CAT 4 at 40. Every pick above prints a number at or above 8 — that's the bar for CAT 2, and it's why I refused to include anything that leaves the figure blank.
