I ordered these for my husband as nice looking shorts that would be casual and comfy. The Large fit his 35" waist ok, a slightly baggy around the crotch. The material is lightweight and they are decent quality for the price. We were both not a fan of the slightly shiny sheen of the material and the khaki color is not a neutral khaki, it is more peach or coral undertoned. He was wearing a garment washed coral pink tone T-shirt when he tried these on and it clashed horribly. Might have looked better with a black or dark shirt but just not an easy khaki that goes with everything unfortunately. Because of the sheen and color he probably won't wear them and we will just donate.

Order larger than they suggest.

Size: XX-Large, Color: Black

Do not listen to size suggestions. These are sized in China. Everything runs much smaller than what they are claiming. Amazons suggestions do not take this into account. They also don't feel like twill, maybe some kind of nylon woven like twill? Not sure.

Nice looking pair of shorts

Size: X-Large, Color: Dark Grey, Size: X-Large, Color: Dark Grey

I ordered these to have as a casual option for the warm weather. These are made of 95% polyester, but feel soft and comfortable. They are of good quality and seem very durable. The material is fairly thick, but still lightweight. I love that the pockets have zippers to keep my items secured. I did not find any loose threads or visible defects. Good value for the money.
