Lightweight Moisture-Wicking Performance and Maximum UPF 50+ Sun Defense

The Mammut Sun Peak Cap is a technical, low-bulk hat purpose-built for fast-and-light mountaineering, alpine trekking, and high-output trail runs on blistering summer days. Constructed from a premium, eco-friendly recycled polyester stretch blend, this lightweight cap delivers an unrestrictive, adaptive fit that contours smoothly to your head shape. The advanced performance textile is engineered to actively dump excess body heat and wicks moisture away instantly, ensuring you remain cool, dry, and comfortable from sudden alpine sunrises to exposed afternoon ridgeline pushes.

Optimized for intense solar exposure in thin mountain air, the cap features an exceptional UPF 50+ sun protection rating to safely shield your scalp from damaging ultraviolet rays. The anatomical design incorporates a sturdy, pre-shaped visor that effectively cuts through piercing alpine glare, preserving a clear and focused field of vision on technical singletrack. Finished with a highly breathable layout, a soft internal sweatband that stops stinging perspiration from reaching your eyes, and a low-profile adjustable rear closure, this dependable trail cap ensures a secure, personalized fit that won't slip during high-velocity mountain motion or in heavy gusting winds.
