Patagonia Men's R1 Air Zip-Neck Green Gray, Size M Purchased last year from an authorized retailer. It's lightweight, comfortable, and excellent at both retaining warmth and preventing overheating. I'm selling it because the size doesn't fit me, and I bought a different size. I haven't worn it much, so the condition is good. The R1 Air Zip-Neck is a lightweight, breathable, and quick-drying technical fleece, perfect for high-output activities in cold conditions. It's made with 100% recycled polyester in a construction that keeps you comfortable during activity. Made in a Fair Trade Certified factory.
