Familiarity: I've put it through the wringer
Fit: True to size
Keeps the rain out but definitely not breathable. At the same time, waterproof usually means that it's never breathable in my experience. So this does the job of keeping my buddy dry and is super light and thin. Bought this for a friend 5'11" 210lbs with an athletic build in an XL.
