The Rab Xenair Alpine Flex Jacket is a versatile, lightweight, and packable piece of active insulation designed for high-energy mountain adventures. Combining body-mapped insulation with breathable Thermic stretch fleece side panels, this jacket offers exceptional thermoregulation, ensuring you stay comfortable during tough ascents and mixed conditions. Whether you’re layering it under a shell or wearing it as a standalone outer, the Xenair Alpine Flex adapts to your activity level, providing warmth when you need it and breathability when the pace picks up. Its innovative design makes it a go-to choice for climbers, mountaineers, and hikers who demand performance and adaptability in challenging environments.

Crafted with precision, the Xenair Alpine Flex features 40gsm PrimaLoft Gold Active+ insulation, which delivers excellent warmth-to-weight ratio and retains its thermal properties even when damp. The inclusion of uninsulated panels in key areas enhances breathability, while the 20D Pertex Quantum Air outer fabric provides a balance of wind resistance and air permeability. The precurved and articulated sleeves ensure a natural range of motion, and the lightweight YKK VISLON ® centre front zip with chin guard adds comfort and durability. Practical touches like the dual YKK zipped hand pockets—one of which doubles as an integrated stuff sack with a harness attachment loop—make this jacket as functional as it is technical.
