Warm breathable water and wind-resistant and stylish what more could you want from a technical mid-layer' The R2 TechFace Fleece Jacket is a rugged update on Patagonia's performance-oriented mid-weight R2 Fleece and we are big fans. The original R2 offered stretch and moisture management to dry quickly when sweating on a rigorous alpine climb. So Patagonia updated this version with a TechFace exterior that's highly water and wind-resistant to shed light snowfall when you're backcountry touring.
