When you’re pushing yourself in fast-changing weather, you need active insulation you can put on and leave on, keeping you comfortable through fluctuating temperatures and peaks and troughs of activity.

Versatile, breathable, and packable, this is an ultralight version of Rab's definitive synthetic insulation for high-energy ascents. Wear as a technical outer for fair-weather objectives or a warm midlayer when the mercury drops, it features a new, improved, even more breathable lining, designed to regulate your temperature and keep you comfortable for longer. Adapting with ease to changeable temperatures and energy levels, it is active insulation crafted to be kept on all day, however fast you’re moving and in any weather.

PrimaLoft® Gold Active+ insulation is positioned in the areas where you need a boost of warmth, with zero insulation in high heat areas such as the underarms, to help balance your microclimate when you’re working hard. The outer of the jacket is made with Pertex® Quantum Air, which deflects stubborn wind while helping to expel moisture. Reach with unhindered mobility thanks to the articulated sleeves, while the adjustable hem seals out the elements. The two hand pockets and internal chest pocket provide handy storage for fast and light adventures without a pack, and one of the hand pockets doubles as a stuff sack with a harness attachment loop.

The Xenair Light is a versatile jacket for any demanding mountain activity, from climbing and mountaineering to fast hiking and scrambling.
