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.
