This tee-shirt is my first Under Armour purchase, and I took a chance by ordering it without ever trying on any Under Armour before. I'm not dissatisfied, but it isn't my favorite tee-shirt. On the positive side: the weight of the fabric is good for exercising, especially for the gym, and it would be a good single layer for outside/warm temperatures. The fit is pretty good (I am average sized and wear sizes 8-10); I don't like really tight clothing and this shirt is loose enough to be comfortable but fitted enough so that it doesn't look like I'm wearing a bag. On the negative side: I am a little short-waisted, and the shirt is long for me and bunches at the top of my hips, which I don't like but accept. Also, the vee-neck is not a very strong vee (pictures of this shirt are true in that respect). A lot of technical tees are like this -- designed more for function than for style maybe -- and vee-necks are essentially a crew x vee hybrid. I prefer a true vee-neck. Lastly, the fabric has a slightly rough, scratchy feel, which seems characteristic of today's technical fabrics. It's not clear to me that the cost in "hand" is worth the added function of "wicking" in this instance. Overall, I consider this shirt fine for the gym or for an hour-long run, but I wouldn't want to spend a lot of extended time in it.

This is ideal for wearing layers of clothing or if you're dressed in a short sleeve over this one. However, I personally prefer the long sleeved version by the same company. 4 stars

Arrived within a short time.
Glad you had my size. Most sport stores didn't have an XL in stock. 5 stars
