Patagonia's Micro Puff collection is a master class in doing more with less, packing ridiculous warmth into a package so light you'll double-check if you remembered to pack it. The secret sauce? PlumaFill insulation - Patagonia's synthetic wizardry that mimics down's warmth and packability while keeping you toasty even when wet. Unlike traditional puffies that turn into cold, soggy messes in damp conditions, these pieces keep bringing the heat. Whether you're going ultralight in the backcountry or need a just-in-case layer that disappears in your pack, the Micro Puff family delivers an almost supernatural warmth-to-weight ratio that'll make you a believer from the first wear.
