RAB Xenair Alpine Flex Jacket 49843598

Versatile midlayer

The Xenair Alpine Flex Jacket from RAB is a lightweight hooded jacket designed for colder days in the mountains. With a regular fit and low-profile design, it works equally well as a standalone piece when temperatures drop or as a midlayer under a shell in wind or light precipitation.

Adaptable performance

Built with a 100% polyamide shell and PrimaLoft® Gold Active filling, this jacket balances durable protection and reliable warmth without weighing you down. Stretch panels and a fleece-backed interior enhance mobility and comfort, while breathability helps manage moisture during high-energy pursuits.

Insulation explained

PrimaLoft® Gold Active is a water-resistant synthetic insulation that retains loft even when damp, delivering warmth and compressibility similar to down. Thermic™ construction refers to how RAB zones and secures the fill to maintain consistent heat retention without restricting movement.
