An absolute classic, the Patagonia Nano Puff Vest is one of our favorite ultralight core insulators for trips to alpine zones, whether we're climbing a new route or skiing a remote couloir. Its lightweight insulation adds warmth that doesn't overwhelm, and we can rely on it even in wet places. Once we've warmed up, the vest stows inside its own pocket for compact convenience on our harness or in our pack.
