Stio Men’s Fernos Vest

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.

Fabric

Shell and Lining: Relance™ Primeflex, 50 Denier Microfiber Mechanical Stretch Plainweave, 100% Polyester,  85g/m2 with 80/20 DWR finish

Relance™ Primeflex 100% polyester microfiber offers better drape and wicking than that of normal polyester fibers. This fabric features a soft hand, comfortable stretch, wind resistance, and excellent resiliency and strength. 

 

Insulation: PeakFill™ Active Insulation, 57% Polyester, 43% Recycled Polyester, 40g/m2

Our PeakFill Active proprietary insulation balances warmth and breathability to maintain lasting
athletic comfort across the entire conditional range. Designed to keep core temps regulated, the
synthetic fiber fill draws on a spiral filament structure to enable greater stretch, faster recovery and
quicker dry times than traditional lofted insulation whether rolling slow at valley level or working hard up in the alpine.
