The 5.11 Stryke Pants with Flex-Tac® is the next generation of 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 these ripstop pants are superior to other cotton/spandex fabrics currently in the market.
These 5.11 pants are both stain- and fade-resistant and come out of the wash ready-to-wear. The silhouette has been redesigned with a sleeker, faster look utilizing slanted inset side cargo pockets. 
In addition to the thigh cargo pockets, there are also two off-seam side pockets, two accessory pockets on each side, and two back flap secured wallet pockets to provide you with maximum storage capacity. The knees are discreetly reinforced with knee pad access inside. Another nice feature is the two front belt loops also double as a badge holder.
