used this as a mid layer on a 26 mile hike in the catskills during november. it gets COLD when the sun disappears. I'm a fairly small dude. Fit isn't tight, but not loose. Construction is good, after that long hike and a good washing, still feels new.
I am 5'11, and a slim build. I usually take a large in MH products. I ordered the large in this Micro-stretch Zip-T and It was very long, and had a boxy fit even though the description said Active fit. I do not believe that it will shrink so I am exchanging it for a Medium. Nice fleece, the pocket doesn't look too bad, other than the fit it is everything that was described.
