Just got back from a few weeks in Peru and the Xenon X was AWESOME. Super light, soft, and comfy, and because it packs down small, I was able to bring it everywhere. It came especially in handy in the Sacred Valley and Cusco, where the nights can get quite chilly. (My partner, who only brought his favorite Carhartt hoodie, was pretty jealous!)
