The Patagonia Men's Nano Puff Vest is a light, weather resistant men's insulated vest that keeps your core warm without bulk in the arms. Its PrimaLoft Gold insulation stays warm even when wet.
A vest is the layer you end up wearing most days. This one is warm, packable and easy to throw under a shell.
Climbing, hiking, layering and everyday wear. Great for cool mornings on the Monarch Crest.
