I bought this shirt to wear running - the description sounded like it was a somewhat synthetic/technical fabric and would be great to wear on cold runs in the winter, and it had been favorably reviewed so I thought I'd try it out.  I normally wear a size medium, so I got an XL since it runs very small.  The shirt is loose on me everywhere except the neckline, which is way too tight for me (I have issues with things touching or near my neck in general, so I'm probably overly sensitive to this).

The reason for the one star review, however, is the material.  It's stretchy, quite thick, and kind of scratchy.  It doesn't feel like any technical fabric I've ever worn, nor does it breathe at all, which is important to me on my runs.  I've worn it exactly once, and I was so uncomfortable with it on that run that I have since stared at it in my closet and chosen every other long sleeved running tee I own (including both cotton and technical fabrics) when I've gone for a run since purchasing it.  This will end up on the donation pile very soon.  Very cute colors and it had potential, but this is the worst running shirt I have ever bought.
