The Rab Men's Microlight Windstopper Hoody is a windproof down insulator designed for year-round mountain pursuits. It follows the same design as Rab's popular Microlight puffies, except Gore-Tex's Windstopper fabric adds durable windproof protection for brisk breezes and frigid winds. The down insulation has a light, lofty, packable 700-fill rating, and a hydrophobic Grangers finish retains the down's lofty warmth in moisture-riddled environments. Rab micro and nano baffled the windproof, downproof Pertex Quantum lining to keep the down in place so you can count on its reliable warmth for years to come.
