There is a general preference for synthetic material for strenuous activity, but it is not my preference. These sport shorts are one of the few left in the market that are made of cotton, so I was glad I found them. The fabric is on the thinner and lighter end, so not like fleece lined tracksuit material, but this is appropriate for what I use them for. I'm not a fan of the single-loop drawstring, but I guess I could cut it to create two loose ends if I needed to. Also, they wear quite big. As someone who has a 92cm/36" waist I would normally buy a large size, but in this case I needed to buy medium.
Overall, in my opinion they are good quality for the price.
