Arc'teryx Cerium Vest Mens

Arc'teryx Cerium Vest Mens delivers high warmth for minimal weight, pairing premium down performance with a trail-ready build. This men’s outdoor vest is made for layering on hikes and thru-hikes, adding core insulation without restricting movement. Down Composite Mapping places synthetic insulation where moisture is more likely to collect, while down stays in key zones to keep heat where it matters. Zippered pockets, an internal security pocket and a included stuff sack make it easy to carry and manage essentials on the move.
