Patagonia Women's Capilene 2 Zip Neck A lightweight, fast-drying, high-performance zip-neck ideal as a first layer for high-endurance activities in warm-to-cool temperatures. The open, highly breathable knit and feathery weight of Capilene® 2 affords unhindered airflow, excellent wicking for endurance activities in warm to moderate temperatures--it's also our fastest-drying Capilene®. Because of its low-bulk design and streamlined fit, Capilene® 2 also acts an excellent layering piece beneath Capilene® 3 or 4 during colder weather. The curvilinear construction provides an updated, fast-forward fit, with seams that won't chafe under a pack or climbing sling. Made of quick-wicking, fast-drying 54% post-consumer recycled (and 100% recyclable) Capilene® 2 polyester, with Gladiodor™ natural odor control. Made in USA.
