Great quality at a reasonable price. The cotton material is soft and comfy. The medium weight material is good for layering. Since it's not to heavy, it can also be used on warmer days to keep the sun off.
I like buying the MEN'S small tee because the arms are always long enough! Great shirt right out of the bag, feels smooth, washes and dries extremely well and when I iron it, just to get some wrinles out, it looks like new! I wear mine under the polo shirt my company provides (which is short sleeve) and I also wear mine under a denim shirt. I will definately buy more of these!
