The 5.11 Stryke Pant with Flex-Tac is the next generation of the Tactical pants. Flex-Tac is a revolutionary fabric utilizing proprietary fibers and developed exclusively for 5.11 Tactical. The lightweight, breathable, poly/cotton ripstop incorporates mechanical stretch yarns, meaning the stretch and recovery of the fabric is achieved without the use of spandex. As a result, the breathability, color retention, and durability of the Flex-Tac is superior to other cotton/spandex fabrics currently in the market. Proven 5.11 Tactical comfort and durability. Self-adjusting tunnel waistband for comfort. Badge holder front belt loops. Quick access, low-profile angled pockets. Genuine YKK zippers and PRYM snaps. Discrete double knee with interior knee pad pocket. Fade and stain resistant fabric.
