Tech & Features

When conditions are mixed and activity levels fluctuate, this lightweight synthetic insulated jacket delivers the ultimate balance of warmth and breathability to keep you comfortable whatever your day throws at you. Filled with dual weight PrimaLoft® Gold Active+ insulation which is lighter in hot spots to help regulate your temperature, it’s a versatile jacket which can be used as a technical outer on fast summer hikes or a warm, hardworking midlayer in cooler conditions. Now featuring a new, even more breathable lining, the Xenair Alpine Light expertly deals with changes in energy and temperature without you needing to remove layers.

The jacket is equipped for moving upwards, with sleeve articulation refined for climbs and scrambles, and a close-fitting hood which fits seamlessly under your helmet. Three zipped pockets provide stash space for your map or snacks, with one inner chest pocket doubling up as a stuff sack with a harness attachment loop. The elasticated cuffs pair easily with gloves, while the single-sided rear hem adjustment eliminates draughts on chillier missions.

Featuring an innovative lining designed to keep you comfortable for longer, the Xenair Alpine Light Jacket offers body-mapped insulation for your most action-packed pursuits.
