One important positive note: these are long enough for taller folk. I have problems (particularly with undershirts) with shirts not being long enough, and this fits me well.
The quality of the shirt is much better than my other undershirts. I'll likely use this as a gym or pajama shirt. If I'm wearing a T-shirt to go out, there are better T-shirts for just a few dollars more. This is an undershirt and is priced accordingly. The shirt is soft and the thread count seems high enough that it's not constantly going to be covered in fur from my cats.
My only complaint is that the shirt is about a full size larger than the shirts I'm used to wearing. I usually wear more fitted T-shirts, like Next Level Apparel and American Apparel. The fit on this shirt is actually similar (taller, not as boxy), but the sizing is more in line with traditional T-shirts.
TL;DR - If you're taller and you want a soft, well-made undershirt, this is what you're looking for. If you like shorts shirts or want a nice shirt to wear out, be cautious.
