The Patagonia Men's Nano Puff Vest offers lightweight, windproof warmth with PrimaLoft Gold Insulation in a packable 100% recycled polyester design.
The Patagonia Men's Nano Puff Vest delivers lightweight, windproof warmth and exceptional packability for core temperature regulation during outdoor activities. Built with a 100% recycled polyester ripstop shell and lining with a Durable Water Repellent (DWR) finish, this versatile midlayer sheds light moisture and blocks cold gusts. It is insulated with 60-gram PrimaLoft Gold Insulation, constructed from 100% postconsumer recycled polyester, which retains 98% of its warmth even when wet. A signature brick quilting pattern with horizontal lines on side panels stabilizes the insulation and enhances durability. Complete with an adjustable drop-tail hem and an internal zippered pocket that doubles as a self-stowing stuffsack with a carabiner clip-in loop, this vest provides high-performance warmth without the bulk.
