The Rab Men's Cirrus Flex Hoody is an insulated full-zip offering lightweight warmth worthy of year-round mountain adventures. Whether you're winter hiking or summer alpine climbing, the Cirrus Flex Hoody offers free-moving performance and lightweight warmth for year-round exploration. It's lofty and packable like a down insulator, but since its insulation is synthetic, the jacket retains its lofty warmth in wetter environments. A windproof, water-resistant shell adds weather protection while remaining remarkably breathable, and Rab added stretchy fleece panels to provide freedom of movement up and down the mountain.
