Comfortable & Dad-Bod Approved!
Size: X-Large, Color: White, Size: X-Large, Color: White
I purchased this shirt in advance of our 10th Anniversary Cruise, and I'll say it was a success! I had never worn a shirt like this before, but I am now a fan. Cool, breathable, comfortable, and my wife loved it! Definitely Dad-Bod Approved. Quality was nice and I think was priced fairly well (might have bought on a sale). The size was perfect. I'm 6'2", 275lbs in these photos, and the XL was a great fit.

Not bad so far
Size: Small, Color: Light Yellow
mixed feelings about the quality... only worn/washed once and there are some dangling threads which I had to cut off which might lead to further degradation of longevity etc. The fit is a bit snug between S and M, I chose small regarding the closest fit to my chest size but it's ok. The fabric is thin so if you are a guy that doesn't mind showing off your form and fitness this shirt is flattering. The fabric is texture, light and thin so there is comfort regarding the lightness of wearing it. One could go a size larger for looser fit and more comfort but I actually like the tighter fit.

Perfect summer shirt...
Size: 3X-Large, Color: White
I am one that ALWAYS look at the 1 star reviews first. When I brought this shirt I did not... I brought 4 more in different colors. I have now looked at the 1 star reviews and I have to disagree.. Most say they are too thin. When it's 90 - 100 degrees outside this shirt is PERFECT.. It is airy and relaxing. I found it to be also perfect in size. I came back to order more but they don't have a few colors I am looking for. This worked for me all the way around..

Flattering and classy
Size: Medium, Color: White
Thin but I love it that way. Is not overly wrinkled after ironing but wrinkles terribly when washed. Fits well not tight or too loose. Buy your exact size. The white is very classy.
