Casual but not sloppy. Great summer apparel.
Crazy good value. I’m 6’, 185 and I should’ve bought mediums. Large is a little too big. These shorts breathe wow, look great in the summer, and are casual, but not sloppy.

Lite and breathable
Size: Medium, Color: Black
I like these a lot. They are lite and will be perfect for our vacation in the tropics. They hit perfectly long enough/short enough on the legs and the color is as described. The material is a little thin but we it feels more like linen. The elastic waist helps to make it comfortable and flattering. Overall, it was a great value for the money.

Dark Grey color is more like brownish purple
Size: XX-Large, Color: Dark Grey
The fit, comfort and value is good. The color is not as described; they are not "Dark Grey" as described. Imagine UPS delivery driver brown, but faded. They are what I can best describe as purplish brown. Definitely not the color I was looking for.
