Like a cross between a shell and a technical fleece, the R1® CrossStrata Jacket is warm, stretchy and breathable like our Regulator® fleece, but with the added benefits of abrasion and weather resistance. This slim-fit, cool-weather crosslayer was designed for extended versatility in shifting mountain conditions. Made in a Fair Trade Certified™ factory. The Women's R1™ CrossStrata Jacket is fully backed by our Ironclad Guarantee and you can find it on Patagonia.com. | Patagonia Women's R1® CrossStrata Jacket in Black, Small - Polyester/Spandex
