5.11 Tactical
Fabric Development

While safety trumps comfort for workers exposed to hazardous conditions, it is nonetheless an important consideration when choosing a uniform program. Now, thanks to 5.11, both receive equal attention. In 2007, 5.11 introduced what is known as FR-x3 fabric, a breakthrough in fire-retardant technology that feels “broken in” from day one. Although it feels great, this state-of-the-art material doesn’t shrink, curl, melt or drip when exposed to flame and instantly self-extinguishes.

FR-x3 fabric was originally developed for use by special forces as a next-to-skin alternative to non-fire-retardant shirts. Over the past couple of years, however, 5.11’s Tactical Series received numerous requests from first responders, firefighters and EMS operators asking for apparel developed specifically for them. The resulting apparel is ideal for all public safety personnel due to their similar operational needs.

While it is another weapon in the arsenal of FR products, it is import to note that the fabric isn’t designed to provide exterior protection like turnout gear. Rather, it is worn as a base layer that delivers enhanced skin protection underneath a uniform during fire rescues and other volatile situations. Because the fabric doesn’t catch fire or melt onto the skin, it’s safer than wearing regular cotton.

Exclusive to 5.11 Tactical, the fabric contains a proprietary blend of 51 percent S.P. cotton and 49 percent FR-x3 modacrylic fiber. It offers cotton’s natural breathability, comfort and ease of care, yet its fire-retardant properties are permanent. The FR assets are integral to the fabric and won’t wash or wear out.

When exposed to flame, FR-x3-blended fibers create a char barrier that offers extra skin protection and greater safety. The fabric’s high cotton ratio gives it excellent anti-static properties as well.

FR-x3 meets and exceeds minimum standards in NFPA 1975 requirements for no-drip, char length and after-flame properties according to ASTM D6413.
