Propper Wildland Pants are certified for use by the USDA Forest Service, delivering excellent fire protection in a comfortable fabric blend of 93% Nomex, 5% Kevlar, and 2% antistatic fibers. Because these lightweight, breathable pants have FR fibers built-in, they will maintain their size, shape, and dependability through repeated washings and wears. Propper Wildland Pants achieve superior moisture management through a proprietary wicking technology that spreads moisture for improved evaporation. An adjustable waist delivers all-day comfort, and adjustable cuffs with hook-and-loop straps secure around your boots. Extra-deep front slash pockets and generous low-profile cargo pockets provide plenty of gear storage. NFPA 1977 Certified.
