The Rab Men's Xenair Alpine Flex Jacket is an active insulated full-zip offering lightweight, packable warmth for climbing, skiing, and mountaineering. Primaloft's fine-tuned its loftiest, down-like synthetic insulation for staying active in the alpine. The Pertex Quantum Air shell sheds light moisture and stays remarkably breathable with full air permeability. Rab paneled the sides in Thermic's stretchy fleece for enhanced moisture management and stretchy mobility. The fit is pre-curved and articulated to also ensure freedom of movement. Ideal as a midlayer and outer layer, the Xenair Alpine Flex also features a smooth-zipping Vislon zipper and a snug, elastic-bound hood for easy layering and reliable coverage.
