The forecast can be unreliable, but you can always trust the Patagonia Men's R1 Air Zip Neck to regulate your temperature and keep you moving no matter how the weather turns out. Designed to keep you dry and comfortable during intense hikes, chilly morning runs, or everyday outings, this remarkably lightweight, breathable R1® fleece wicks moisture and dries quickly so you can push hard and still be at the top of your game. The half-zip lets you adjust ventilation on the go, while the secure chest pocket keeps your essentials close. Crafted from recycled materials, this pullover fleece supports your outdoor lifestyle and the planet you love.
