Superior Warmth, Poor Fit
I have a number of old 3.0 tops and decided to try the 4.0. It does the job keeping me warm while snowboarding, even in extreme cold. But the fit seems off. Last year I bought a 3.0 in size medium and it was too big, so I decided to go with a small this time. As other reviews have also stated, it is very tight in the arms/shoulders and the sleeves don't seem long enough - the thumbholes (a feature I always look for in baselayers) are real tight when I put my hand through. And they get start to hurt within about any hour that I have to pull them off my hands. I'm not a big person - 5'5" and about 110 pounds. I am definitely disappointed with this product and will not buy again.

Arms are so tight
I wanted to love this top but the arms are so tight! I'm 5'5" 130 lbs and fit. I got a small according to measurements. My arms are average and not big or muscular. The armpit area is so tight that it feels irritated within minutes of putting it on. I wish there was slightly more room in the armpits. I'm not sure what's the purpose of making it so tight in this area. I bought this a while ago and can't return and it wasn't a cheap top. I'm pretty disappointed. Otherwise, it is a fine and warm top. If you have very skinny arms and don't mind a tightly rubbing armpit area, you may like this top.

Runs a little big
I went by the measurements and got the small, because I’m size 35in on my chest and my waist Fluctuate to 28-29in. When I got it, it was one size bigger. I wish I went for the XS one even though I’m not within their specified measurements. Overall, I was going for a tighter fit I guess. The small one is loose-ish.

Cold weather game changer
As someone who trains/plays outdoors all year (in Chicago where that can mean sub-zero, freezing rain, etc) it's great to find a shirt that genuinely keeps me warm and comfortable w/o feeling like the Michelin man. And I'm often cold, so that's no easy feat! Two tips for UA: thumbholes! These don't work on any ua top I've purchased. Arms are the right length but too short for thumb holes. If you use them they push into the webbing of your thumb or pull at your shoulder or both. And I'm pretty small (5'4") def don't have the wingspan of an eagle. Easy fix, guys 2nd request: colors. I wear these shirts stand alone for work as an exercise therapist. A few colors besides black would help. Thanks for a great product!
