Uses: winter snowshoeing/hiking/scrambling at -5 to 10 C. Warmth: Excellent, never felt cold in these except in strong winds. The ventilated areas down the back and shoulders help to mitigate backpack sweat. This has replaced my classic thermal smartwool top for active winter trips because that top was often giving me back sweat issues. Fit: This is my only complaint about this top. It's a little short on the torso, exposing my belly to the cold when I raise my arms unless I tuck it into my pants. Otherwise it's a good, snug fit (I'm a skinny 5'7 wearing a Small). Quality: No issues yet after several uses. Good odor resistance.
