The R1 Ultralight 1/2 Zip Top is built for fast moving adventures with lightweight comfort and breathable performance that adapts to changing conditions. Designed for everything from technical climbs to rugged backcountry traverses, it combines a lofty interior feel with a smooth abrasion resistant exterior that stands up to demanding terrain. The fitted silhouette layers easily under outerwear while maintaining unrestricted mobility for active pursuits. A deep half zip neckline allows rapid ventilation when intensity rises, while the streamlined construction keeps bulk to a minimum for comfortable layering under packs and harnesses. Thoughtful details like the unique sleeve construction and low-profile cuffs help reduce pressure points during long days outdoors. Made with recycled materials and Fair Trade Certified construction, this versatile layer blends technical performance with responsible design. | Patagonia Women's R1 Ultralight 1/2 Zip Top
