Excellent condition, worn fewer than ten times. I hate to get rid of it, but I need to free up space in my home. The Nano-Air uses specialized synthetic insulation and a stretchy face fabric to create a warm, yet breathable jacket. When the mercury plummets and the grade steepens, I reach for the Nano-Air every time, which is a rare quality because it’s usually warmth or breathability, not both. Designed for active pursuits in the colder months, this is the perfect layer for cycling, climbing, hiking, or any other highly aerobic activity. Once you zip up you won’t want (or need) to zip down.
