Comfortable Base Layer Protection

Protection isn’t complete until it lives next to your skin. TechT4™ fabrics provide the first layer of defense and the first layer of comfort for t-shirts and other undergarments. This remarkably innovative fabric brings ease-of-wear and flame-resistance in an incredibly lightweight base layer textile at 4.8 osy (160 gsm). Tecasafe® Plus TechT4™ makes the perfect addition to multi-layer, flame-resistant clothing systems. Tecasafe® Plus TechT4™ is non-contributory, which means that it won’t ignite, melt or drip as it enhances the protection of FR outer layers. TechT4™ also features COOLDERM™ Technology and is extraordinarily soft and comfortable, providing better protection than cotton. Tecasafe® Plus TechT4™ wears like an athletic t-shirt with the added bonus of inherent FR protection and moisture management. It is a fabric that looks good, wears well and will give firefighters the comfort and protection they need beneath their stationwear and bunker gear.
