Overpriced for a cheaply made shirt. The hems are glued down, not sewn.
Color: Grey/Black Square, Size: XX-Large, Color: Grey/Black Square, Size: XX-Large
I'm not sure how well this shirt is going to hold up, but I'll give them it's lightweight and cool! LOL There's almost nothing to it, it's so light. Mrs Aloha Friday is really crafty, but doesn't do much sewing. It's like she made this shirt with those tapes that you use to hold a hem temporarily, with an iron. LOL She's now got the idea she can make me shirts herself by just gluing them together! ;o) Neither of us is sure how well this will hold up to multiple washes. I'll edit my review if it falls apart. I think the price is nuts for what you get, at $27 as of this writing. There are literally holes in the shirt! I'd feel better recommending it at around $10. If you need something lightweight, yet still an actual shirt, here ya go. The problem is, I'll need to wear an undershirt under this or I'll just sweat right through it in the heat, and it will show the texture of everything it rests against, like the hairs on my chest. Or worse, they'll poke through the holes! Gah!! LOL So sorry for that imagery. I got the Grey/Black square.

Esabel.C Mens Mesh Polo Shirt Moisture Wicking Short Sleeve
Color: Lightblue Rhombus, Size: Large
This is the Esabel.C Mens Golf Polo Shirt. It's moisture wicking works out great. I wear it quite often golfing. Very comfortable and light weight. The color I got was the Lightblue Rhombus. They have 6 different ones to choose from. And the price is not bad either. As far as the size goes, I went by their chart, which was large, and it fits very well. I've had no problems with it. Like I said, I wear it very often.

One of my favorite golf shirts
Color: Lightblue Four Dots, Size: Large
I ordered this golf shirt and it's becoming one of my favorites. I'm a medium build 6'3", 42" chest and the large fits me very well with plenty of room for movement but a nice trim look. The lightweight material is soft and breathable, with a small bit of stretch. It's easy to care for with machine wash and dry, and comes out wrinkle-free. This shirt is very well made and is a good value - I highly recommend it.
