This is a GREAT product line! Excellent fit!
Size: XX-Large, Color: Whiteblueleaf, Size: XX-Large, Color: Whiteblueleaf
Ordered 5 of these for a trip to Hawaii- and they did NOT disappoint! I don't do well in humidity, and these were the solution. The fabric is light but strong, and I am a bigger guy who usually where's a 2X Tall- the 2X was perfect. Just the right length, not too short like almost all of the other shirts I get off Amazon. Cool and moisture wicking without and discoloration, no embarrassing sweat marks and they do not hold any odor. Beats the regular cotton shirts for sure. After washing the colors, fit and finish have all held up wonderfully!

I love golf shirts !
Size: XX-Large, Color: Greengolf
I really love the design and feel of this shirt. The rub, is that it’s wrinkled all the time!! Even after a couple of washings. Also tried to water spray and let hang dry and also redry in the dryer. I’ve also worn it golfing. Hoping it would get better. Maybe my imagination, but does seem a little better. Golfing isn’t supposed to be a fashion show. But comfy nice shirts a must. I have this same shirt in black background. Love it, and isn’t as wrinkled. Black isn’t the best color on really warm summer days. Might keep this for a bit and see if it settles. No TV cameras on my golf game, ha! Just seem to play better when I feel good and look good. And most courses require collared shirts. Ok! Washed it again and let it hang dry! Wrinkles are gone!! Great shirt!! Now have it in several colors! The lighter colors are great!! Fend off the heat and nice enough to wear to church!!

Great golf shirt
Size: X-Large, Color: White Rhombus
Great golf shirt! Husband loves it, I will order more! They are a little longer than he would wear because he doesn’t tuck his in but over all great. Price is decent compared to what you spend in stores these days. The material is very light and great for south Arkansas heat.
