Evolution DST Pants. Engineered for elite-level performance, the Evolution DST Pants deliver the perfect blend of flexibility, durability, and ventilation for serious riders. Constructed with DST (Durable Stretch Technology) using four-way HEX-Stretch fabric, these pants allow for unrestricted movement while withstanding the demands of aggressive riding. Strategically placed laser - cut perforations and stretch-mesh ventilation zones keep air flowing in high-heat areas, while leather heat shield panels with Aramid stitching provide superior protection against heat and abrasion. The BOA Fit System enables quick, precise waist adjustments for a custom fit on the fly. With a 900D full-floating seat, pre-shaped knees that accommodate guards, and a breathable mesh liner for added comfort, the Evolution DST Pants are built to move with you - every jump, corner, and straightaway.
