Cody M.wrote a review of SmartWool MerinoMax 1/2-Zip Sweater - Men's on April 3, 2014
Familiarity: I've used it once or twice and have initial impressions
This is my first SmartWool product (besides their awesome socks) and I was disappointed. I almost wonder if I got a knock-off, but I have more faith in Backcountry.com than that. I bought a medium for my 6'0", 165-lb frame. The length is too short, so my undershirt will come out the bottom. The sleeves are too short (I do have kind of long arms) so the thumb holes are a little uncomfortable. More importantly, the fit is not nearly as tight as it looks in the picture. The sleeves are loose which allows air to blow up my arm and the torso is also pretty loose. I also expected the material to be a lot softer.
It works well enough, but for the price, I think you could get something a LOT better. If you still want one I would try to find it in a store so you can try it on.
