Patagonia W's R1 CrossStrata Hoody is a warm, technical women's fleece that is perfect for your mountaineering outings. Inside you'll find an R1 fleece with a zig-zag weave that provides excellent thermal insulation but does not keep excess heat inside. The outside, on the other hand, features a very durable fabric that will protect you from the wind with DWR treatment. Patagonia W's R1 CrossStrata Hoody Women's technical polar fleece
