R1 Ultralight Half-Zip Men's

Patagonia R1 Ultralight Half-Zip

The Patagonia R1 Ultralight Half-Zip is a lightweight, breathable fleece built for moving fast in the mountains. Its lofty, breathable construction provides comfortable warmth without feeling bulky, while the smooth outer face layers easily under a shell or harness. At just 8.47 oz (240 g), it's an easy choice for climbing, hiking, backpacking, and other high-output adventures where every ounce counts.

The deep center-front half-zip makes it easy to dump heat on steep climbs and gives you enough room to pull the layer on or off without removing your helmet. A unique single-panel sleeve construction keeps seams off your shoulders, making it more comfortable under a backpack, while the slim fit provides unrestricted mobility.

Two vertical chest pockets keep a phone, snacks, topo, or other small essentials close at hand without adding unnecessary bulk. Low-profile cuffs provide full wrist coverage and can be pushed up over your forearms when you need to cool down, while the longer hem stays tucked under a harness.

Made with 100% recycled polyester and produced in a Fair Trade Certified™ factory, the R1 Ultralight Half-Zip is a versatile mountain layer for anyone who wants breathable warmth without the weight.
