Patagonia Nano-Air Insulated Jacket - Men's Textile Green, XXL

A lot of outdoor gear is billed as "The only (insert product here) you'll ever need", and while that kind of statement can only be so true, Patagonia gets pretty much as close to the mark as we can with the Nano-Air Insulated Jacket. Designed as an active insulating layer for high-output alpine missions in cold weather, this jacket delivers toasty warmth, breathable performance, and ultimate next-to-skin comfort that makes us want to keep rocking it around town long after we've put our ice axes, skins, or crampons away. And while Patagonia has expanded their Nano-Air line to feature lighter and more hybrid jackets, the original jacket still stands as the warmest and most versatile for all cold-weather activities.
