Patagonia Men's Nano Puff Vest Old Growth Green

The Patagonia Men's Nano Puff Vest is a lightweight synthetic insulation layer built for reliable warmth across changing conditions. Originally developed for climbers needing a weather-resistant, packable vest that could continue performing when damp, it remains one of Patagonia's most versatile layering pieces for everyday outdoor use. In Old Growth Green, it brings a clean, functional look that works equally well on the trail, at the crag, and in daily wear.This vest combines a 100% recycled polyester ripstop shell with a matching recycled lining, keeping overall weight low while maintaining durability for repeated use. Both shell and lining feature a DWR finish made without intentionally added PFAS, helping shed light moisture in variable weather. Inside, 60 g PrimaLoft® Gold Insulation Eco, made from 100% postconsumer recycled polyester and produced with P.U.R.E.™ technology, delivers strong warmth for the weight and retains insulating performance when wet.The Nano Puff Vest is designed for efficient layering. A refined shoulder and armhole shape improves mobility and comfort, while the slightly narrower cut and longer body make it easy to wear over a base layer or under a shell. Signature brick quilting, paired with horizontally quilted side panels, helps stabilize the insulation, reduce bulk, and improve durability whether worn as an outer layer or as part of a cold-weather system.Functional details are kept precise. The center-front zipper includes a wicking interior storm flap and a zipper garage at the chin for comfort. Two zippered handwarmer pockets provide secure everyday storage, and an internal zippered chest pocket doubles as a stuffsack, complete with a reinforced carabiner clip-in loop for packability on the move. A drawcord-adjustable drop-tail hem helps seal in warmth when temperatures drop.Made in a Fair Trade Certified™ factory and built with bluesign® approved fabrics, the Nano Puff Vest reflects Patagonia's established focus on lower-impact materials and practical long-term use. At 235 g, it remains easy to carry, layer, and rely on through multiple seasons.
