i wear this multi-purpose shirt ALL THE TIME. i wear it skiing, snowboarding, to the office as a sweater, bumming around town, camping, hiking, around my waist in case the temp change, etc. etc. it has probably been through the wash a hundred times or more, and it still looks great. i have a small and am 5'6", 120 lbs. it fits perfectly and looks stylish enough to be a top layer if you want.

This shirt has been great for autumn workouts. It's warm, breathable, and dries quickly.

I think this relaxed-fit shirt runs large. I usually wear a women's medium, but a size small in this shirt is still big enough to layer over a thin T shirt.

I use one for number of months and was time for my wife to get another baseleyer top. She got number of other baseleyer/technical tops from Patagonia, Arcteryx and Marmot, All in size M with perfect fit. However MH sizing is way off!
This top in size M almost fits me and I am 5 11 , 185 lbs. Quality and wokmanship is excellent. Try one on in local store before ordering on line.

Bought this for my mother as a gift. Saying this woman is cold-blooded is an understatement (she can't even wear short sleeves when the temp is in the upper 80's). I wanted to find something that would keep her teeth from chattering even in an Ohio summer. She loves this baselayer. She is 5'2" and only about 100lbs. Don't know what everyone was complaining about in terms of size. She likes clothes to fit a little loosely so I bought the medium and it fits fine. If it keeps her warm a normal person could probably weather anything in this.

I got this for my girlfriend to replace one she got quite a few years back that fit her perfectly. I got the same size this time, XS, and it was at least a size larger. It's a great fleece, but they need to cut the sizing back quite a bit.

This is the best layer for skiing - don't worry about using anything else. This fits real snugly around the forearms, and is super soft on the inside. You can wear it inside out, but I don't see why you would. Any girl that is around 5"9 with a bigger chest will need a large. You will have this shirt for 10+ years and love it every ski season! Also great for mountaineering!

I bought one of these tops for each of my sisters & myself for Christmas & one of my sisters has already bought another one because she likes it so much! They are smooth on the outside & warm & fleecy on the inside-very stretchy, so go down 1 size for a good fit.
