Challenging conditions in the wild are inevitable. Remove obstacles in front of you, not layers. The athletic-fitting Mens Featherless Hybrid Jacket from Marmot fuses a moisture-managing DriClime wicking lining with 3M Thinsulate insulation. This synthetic loose-fiber fill has the same thermal performance as natural 700-power-fill down, yet is water-resistant to maintain warmth in damp weather. The final product delivers functionality in varying conditions and energy outputs to keep you comfortable for the unknown ahead.
