COOLMAX® moisture management: Integrated COOLMAX® filament yarn wicks moisture away from the body to help keep riders cool, dry, and comfortable in warm or variable riding conditions.
Durable stretch construction: Multi-stretch denim construction provides enhanced mobility and unrestricted movement on and off the bike, while reinforced dual seams, overlock stitching, and double stitching enhance structural strength and durability.

Three-position knee protector pockets, spaced 3cm apart and identified by color-coded stitching, allow protector height to be adjusted for optimal coverage and a personalized fit.
Everyday functionality and detailing: Traditional five-pocket construction and a metal zipper fly provide practical storage and a secure closure. Selvedge-style finishing helps prevent fraying, while a leather back patch, branded belt loop and rivets, and an embroidered Astar back-pocket accent complete the construction with signature Alpinestars detailing.
Advanced Knee and Hip Protection: Low-profile, 10 mm Nucleon Morph STEALTH Level 2 knee and hip protectors provide extended coverage, effective impact protection, efficient airflow, and lightweight comfort. Ultra-slim and adaptive, they contour to the rider's knees and hips for all-day comfort.
