Rab Xenair Alpine Flex Jacket – PrimaLoft® Stretch Synthetic Jacket for Technical Alpine Climbing

Description

The Rab Xenair Alpine Flex Jacket is the most mobile interpretation in the Xenair range. It combines active insulation with strategic stretch panels to enhance freedom of movement for technical activities where gestures, range of motion, and breathability are key.

Its hybrid construction makes it an especially interesting option for alpine climbing, technical mountaineering, and any activity where a rigid or overly restrictive jacket limits performance.

At Mountain Group, we place great importance on explaining the true role of each garment within the Rab collection to help you make an informed choice.

Real technical performance

The Alpine Flex stands out for its superior mobility and more targeted ventilation in high-exertion areas. It keeps the core warm, but better allows for movement and heat dissipation during technical maneuvers.
