FR Short Sleeve Base Layer T-Shirt — FR Protection at the Skin Level, Built for Heat
Your outer FR shirt is doing its job. This is what protects you underneath it.
When arc flash or flash fire occurs, non-FR synthetic base layers — polyester, nylon, spandex — melt against skin, turning a survivable incident into a catastrophic burn injury. The fix is simple: an FR base layer that performs at the skin level, so every layer in your system is working for you, not against you.
Built from 5 oz FR modacrylic blend — lightweight, soft, and moisture-wicking — with a 6 cal/cm² arc rating (ATPV) — CAT 1 that meets ASTM F1506. At 5 oz, it disappears under your work shirt. The short sleeve is the hot-weather choice: maximum breathability, zero extra weight, and FR protection from skin out even when it's too hot for long sleeves.
Features:
- 6 cal/cm² arc rating (ATPV) — CAT 1, meets ASTM F1506
- 5 oz FR modacrylic blend — inherent FR, lightweight, moisture-wicking
- Short sleeve — maximum breathability for hot-weather work
- Tagless, flatlock seams — worn against skin all day, no irritation [confirm]
- Gray — pairs under any FR uniform shirt, henley, or coverall
- Sizes S–5XL
Layering tip: pair with our FR Henley (8.7 cal) for a comfortable, fully FR layered system on hot days — or wear under your FR coverall when you need complete skin-to-outer coverage.
