Nice shorts but no fly
Size: Medium, Color: Blue Gray, Size: Medium, Color: Blue Gray
These shorts are well made with three pockets on the sides, 2 standard and one zippered, along with one pocket on the back. They are made of a polyester fabric and do feel as though they will be waterproof. They are well constructed and should hold up well. My issue with these shorts is that they have no fly, just fake stiching on the front. Yes, they say they are for the beach, but that is no reason not to have a fly. Swim trunks are one thing, no one expects a fly on them, but on shorts, yes I do. I always like to include a picture of the laundry instructions,, I hate getting something and discovering it takes special care.

These are keepers for sure
Size: Medium, Color: Dark Grey, Size: Medium, Color: Dark Grey
These are very lightweight and comfortable shorts perfect for casual wear or sportswear. The fabric thickness is perfect. It’s very stretchy but nice and soft at the same time. The material looks to be high-quality in terms of aesthetics and overall this pair of shorts could work for any style type on any body type. Fits perfectly as it should
