Patagonia W's Nano-Air Ultralight Full-Zip Hoody technical fleece women's

The Women's Nano-Air® Ultralight Full-Zip Hoody from Patagonia is a lightweight and breathable technical jacket for women, designed as the ideal mid-layer for high-intensity alpine activities where temperature control is essential. This innovative piece uses 20-gram FullRange synthetic insulation that provides the right warmth without causing overheating during fast movement, effectively protecting against wind and light snow. The outer fabric and lining are made from recycled polyester with elastic ripstop weave, treated with a long-lasting water-repellent finish free of PFAS chemicals to resist light moisture. The design features highly breathable panels under the arms to promote excess heat release, while the Capilene® Cool Lightweight fabric cuffs allow for easy sleeve adjustment on the forearms, ensuring quick drying. The elasticized hood is designed to be worn comfortably with or without a helmet, maintaining a snug profile that does not obstruct vision. Thanks to the slim cut and articulated construction, the jacket fits perfectly under a harness or backpack, ensuring superior freedom of movement at every stage of the climb. Practicality is enhanced by the spacious chest pocket, which also serves as a compression sack to stow the entire garment for attachment to the harness via the designated carabiner loop. Certified bluesign® for environmental compliance and produced following strict quality standards, this 215-gram jacket is machine washable in cold water and represents the ultimate solution for those seeking dynamic and ultralight thermal insulation in the mountains.
