The KRYPTON Inherent Flame Retardant Base Layer Navy is a certified protective first layer that combines inherent flame resistance with everyday comfort. Made from a 60% Modacrylic 40% Cotton anti-static single jersey, it delivers consistent protection in fire-prone work environments while fitting like a regular T-shirt.

If you struggle with treated garments that lose protection after repeated washing this helps — the inherent FR fibres do not wash out or wear off so your safety remains intact wash after wash. The taped neckline and ribbed neck and sleeve cuffs add comfort for long shifts without compromising safety.

• 60% Modacrylic 40% Cotton anti-static single jersey for inherent protection
• 240GSM fabric weight providing measurable thermal barrier
• Certified EN ISO 13688 2013 general requirements
• Meets EN 1149-5 anti-static requirements and EN 1149-3 where applicable

Use it as your base layer under workwear or high-visibility garments. Unlike treated FR T-shirts that rely on coatings, this base layer’s protection is built into the fibres and endures repeated washing. Compared to standard cotton tees it adds anti-static and thermal protection while remaining comfortable.

Certified to EN standards and designed for industrial safety, this base layer is tested and proven as a reliable first layer of defence in hazardous environments.
