It resisted wind better than any of the lightweight jackets we tested. We loved the comfort and mobility of the Xenon X. However, it is important to note that this jacket doesn't breathe well. If you're looking for an insulating layer that prioritizes breathability, check out the Patagonia Nano Air Hoody or the Outdoor Research Uberlayer. The Nano Air, with its soft and stretchy fabric, is our Top Pick for Breathability, and the most comfortable jacket we tested. A more affordable alternative is our Best Buy Award winner, the Outdoor Research Cathode Hooded Jacket. It is just as light as the Xenon X and uses a hybrid design for increased breathability. Our Editors' Choice winner, however, is more weather resistant, and we recommend it for a variety of activities.
Rab updated the liner color for the Xenon X since we reviewed this jacket, but all specs remain the same.
