Choose a vest that keeps the pace for on winter runs, up the skintrack or cruising on Nordic loops. Breathable and lightweight, yet keeps you warm.

Winter runs, fitness skins or Nordic loops are all part of the game for our warm, breathable and uber-aerobic Fernos Vest. The key to its core-warming performance is 40-gram PeakFill™ Active Insulation, a highly breathable, quick recovery, spiral filament synthetic fill. Easily compressible into small spaces like a ski pack or running vest, it lofts back promptly when called on for treeline, ridgeline or rest-break warmth. Mechanical stretch and side-seamless construction enhance mobility and reduce layering friction. A single zip chest pocket secures a wallet and keys, while a rear drop tail and reverse coil YKK® zipper complete the fast, streamlined aesthetic.
