Wiomen's ResponderFR™ Cargo Pants are the most comfortable you'll ever own, with no break-in required, and are dual-certified to both the NFPA 1975:2019 Stationwear standard and the NFPA 1977:2022 Standard on Protective Clothing and Equipment for Wildland Fire Fighting.Our unique wash-and-wear ripstop GlenGuard® fabric is soft to the touch, just like a fine cotton, yet wicks moisture like the best performance fabrics, while being 20% lighter than comparable FR garments. Featuring the stretch waistband (a first for FR uniform pants,) which self-adjusts to your body as you move, they come with a modern athletic fit made to fit the natural curves of your body, and movement-friendly design touches like an articulated knee.
