Imad B.wrote a review of Patagonia Nano-Air Jacket - Men's on December 7, 2017
Familiarity: I've used it several times
Fit: True to size
I used this as my mid layer on Everest Trek in Nov. This is a really good jacket. I wore it inside a hard shell while trekking and just as an outer shell at the lower camps. It is amazingly comfortable and very breathable. I loved it and will be putting it through the wringer.
