Perfect for mountain life, the Rab Men's Graviton Jacket is a technical fleece with midweight warmth for hiking, camping, climbing, or shoveling snow off the driveway. Its 100% recycled fleece has a gridded lining to wick moisture and dry quickly if you work up a sweat. A slim fit lets you layer according to the seasons to stay warm from autumn to spring. Rab designed this full-zip with set-in sleeves to pair with big backpacks comfortably, and a dropped hem stays tucked under climbing harnesses.
