Not bad really
Size: Large, Color: Light Grey Heather
I purchased a size Large and it's just a smidge loose but it's nothing that is really noticeable or uncomfy. I'm about 180lbs at 5'9 with somewhat of a beer belly but not a huge one lol. If you're body is about the same as mine and if you want a more fitted feel them go with a medium. So overall it's very comfortable it's my 3rd Amazon brand type of garment or clothing that ive purchased so far. Still too early to tell just how durable it is but I'll be sure to update that eventually. I use it for work (nothing heavy white collar work) and during the warm seasons I absolutely loath regular cotton style shirts. I'm not a fan of the summer weather so I tend to buy clothing that is more suitable for warm temps. This is 100% polyester and it's breathable as heck. That's what I like most about it. The overall texture and feel is somewhat "rough" but soft at the same time (if that makes any sense) but it's nothing that you'll be self conscious about. So don't let that scare you away. It's comfy and inexpensive and I recommend.

Great quality, seems to run just a little big
This is an excellent quality shirt. While I haven't put the "quick-dry" feature to the test, it definitely feels like it would dry quickly if wet. It has a little bit of weight to it but not so much that it feels heavy, just that you're well aware you're wearing it. I picked up a large and I'm about 5'9 and 175lbs (and 14 neck) - and I feel like I'm swimming in this thing (it's a bit on the bigger side). I'm definitely going to order more, probably several, but will likely drop down to a Medium and see how big a difference it makes. Hopefully it fits better without being too small. Overall, great quality and value - highly recommended (whether for golf, work, or just casual outings).
