Emulated by many, the grid fleece technology has become a staple in most people's active cold-weather layering system. Somehow, Patagonia has created an even better version with the release of the R1 Air. Built from a proprietary "hollow core" fabric produced from 100% recycled polyester, this piece brings a new level of comfort to performance fleece wear. The material looks and feels more cozy than technical, but don't let that fool you — this fleece means business. Whether heading to the crag or the coffee shop, this fleece was the one our testers would always grab first. The low weight combined with the amount of warmth it provides make it ideal for high-intensity activities like climbing and hiking in the cold. The highly breathable "zig-zagged" pattern helps shed moisture and keeps you from ending up a sweaty and shivering mess." Outdoor Gear Lab, 2022. Patagonia Men's R1 Air Fleece Zip Neck Fleece Top
