Low maintenance
Size: Large, Color: White/Black Flower
Washes and dries wrinkle free which is perfect for my son away at college when he has to get dressed up and look nice.

Good buy

Good fit. Looks well built held up in the washer and dryer and still comfortable.

Great purchase!
Size: 40, Color: 01white Camo
I bought these shorts as consideration for team uniform and they exceeded my expectations! Great quality, nice style, comfortable and not too heavy. Material is cotton and the fit is perfect. Got a little bit bigger because I wanted it to be a more relaxed fit but I’d say these shorts are true to size.

fit fine
Size: 42, Color: 01black Camo
tbh, they are a little bigger then I expected. seems like a lot of people claimed they fit small, so I ordered a size up and they are a little more loose then I’d normally want. the material is slightly different, maybe a bit more stiff, but still pretty comfortable for the price. I’d order them again.

Fit well, look good
Size: 34, Color: 01black
bought 4 pair in different colors. They look great and fit well and have some room with the elastic waist. Very, very satisfied. Will buy more next summer for sure.
