The American company 5.11 is the leading supplier of hard-wearing tactical pants. Made using Flex-Tac, this represents the next generation of tactical pants. Flex-Tac is a revolutionary, proprietary fabric with special fibres developed exclusively for 5.11. The pants are lightweight, breathable and flexible without using spandex, because the fabric features 4-way stretch. As a result, the 5.11 Stryke model is extremely colour-fast and dirt-resistant.
