Nice and comfy, light duty and feel great.
Size: X-Large, Color: Light Green
What they may lack in "durability" i.e. very light and thin = not going to last all that long, they make up for in fit [yes even for wide shoulders], comfort and style. If you want them to last, suggest a gentle cycle and just take ot easy on them. They are light, thin, and airy. Nice summer shirt.

A true vacation find!
Size: Medium, Color: Light Green
Really nice choice. Got it for my husband and he really liked the style. I loved how it fit on him and the lightness of the fabric. Great for hot, sunny weathered days, or warm nights. A true vacation find. Both comfy and stylish. He would have preferred it be 100% cotton, but I think he didn't really mind after steaming it. He commented on the color too. A beautiful sage green!

Well made, comfortable and flattering
Size: 3X-Large, Color: Light Green
Nice material. I ordered the 3XL because my hubby has a big belly. It fit him well and was slimming. He wore it as a guest to an outdoor wedding. He looked nice and was comfortable all night.

Nice but short
Size: X-Large, Color: Lavender
Yes, I purchased this shirt for my husband to wear on Mother’s Day. He looked so handsome and the color complimented his skin tone beautifully. The only con that my husband expressed was that the shirt was short but was comfortable and the fabric felt good on his skin. He is 6’3” and usually wears an XLT. Coofandy, Please make these shirts for taller, longer torso men!

Expensive Look Without The Expense!
Size: Medium, Color: Black, Size: Medium, Color: Black
Sizing:
If you’re a true large like me and close to but less than fifteen pounds overweight, normal length and with a 44” chest, buy a medium and use the shirt to inspire you to lose the beer belly. If you have similar dimensions but are overweight by up to thirty pounds, get the large.
Materials: The mediums are manufactured to 70% synthetic, 30% linen—which is a great mix, as is doesn’t have to be ironed after it’s washed and hung to dry, nor does it have to be ironed every time you get up from a chair. I’ve had many 100% linen shirts and sure, they look great after you spend thirty minutes ironing them, just to look like a crumpled up newspaper after you get out of your car. My experience with linen shirts is what brought me here.
Unboxing the shirt:
I threw it on an ironing board the moment I unbagged it. I tried the Synthetic setting on the iron—it wasn’t enough. I then tried the Wool setting and set the steam setting to constant medium to high. It worked great. I didn’t have to press down at all, just lightly glided the iron across wrinkled areas of the shirt. Within five minutes, the shirt looked like a hundred-dollar shirt. The material is light, yet feels heavy to the touch and breathes very well in the heat. The hidden buttons give a clean, modern look that allows the shirt to be worn with anything from shorts and sandals to dress slacks and shoes in a club. I like to wear these shirts, untucked with a pair of jeans and western boots. This shirt is very comfortable, fits nice and is extremely versatile.
