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.

Our PeakFill™ Active proprietary insulation balances warmth and breathability to maintain lasting athletic comfort across the entire conditional range.
