The Octa™ insulation that made our Dawner Jacket a trusted companion for cool, active days is now our go-to vest. Lightweight and breathable, the interior wears soft on skin and is designed in a diamond grid pattern that reduces bulk, creating a sleek shape that holds in warmth while letting moisture escape. The smooth nylon outer sheds wind and weather and incorporates stretch for easy range of motion. It packs small enough to fit into its own zippered pocket, and the adjustable hem seals out sneaky updrafts and customizes fit.
