Evolution DST DBK Pants. The Evolution DST DBK Pants are built for riders who demand top-tier performance, comfort, and durability. Crafted with Durable Stretch Technology (DST) and four-way HEX-Stretch fabric, these pants deliver unrestricted mobility while standing up to the toughest riding conditions. Strategically placed stretch-mesh vents and laser-cut perforations maximize airflow, keeping you cool in high-heat zones. Reinforced with heat-resistant leather panels and Aramid stitching at the knees, the DBK Pants provide essential protection where it counts. The BOA Fit System allows micro-adjustable waist tuning on the fly, while the pre-shaped ergonomic knees are compatible with most guards. With a full-floating 900D seat and breathable mesh panels, these pants are engineered to move with you - on the track, trail, or anywhere your ride takes you.
