The M Rider Essentials Zip from Peak Performance is a flexible midlayer made from quick-drying functional fabric (86% recycled polyester, 14% elastane) that offers both comfort and freedom of movement during active days. The jacket has a softly lined double-layer collar with chin guard to prevent chafing, and practical zippered hand pockets for secure storage. A technical layer that works equally well under a shell jacket or on its own on milder days.
