Monika R.wrote a review of Patagonia Nano-Air Jacket - Women's on February 4, 2016
Familiarity: I've used it once or twice and have initial impressions
Fit: True to size
So warm, this jacket.
I'm always cold, and this thing feels like never having to get out of bed. If only they made little finger jackets for those winter crack climbs. But I'll settle for an extremely warm torso and excellent flexibility throughout. Not sure how the fabric will hold up to continual scraping up against things or washing yet, and the arms seem a little wider than necessary, but I have full faith in Patagonia's stuff.
