I bought these to wear as liner shorts with a baggy pair of over-shorts for mountain biking, so I enjoy the thinner material. It's very comfortable and perfect for my use. I find mesh liner shorts to be itchy and generally poorly constructed and uncomfortable, so I'm happy to find these! I liked the waist band on Pearl Izumi's P.R.O. In R Cool short better than these, but I liked the thinner, lighter material better on these Ultrastar shorts, so these won.
Peal Izumi got it right with the design of this short, especially the seams and panels up to the waist band. The best fitting and most comfortable shorts as far as the waist is concerned that I have tried on, especially for a curvier, pear-shaped person. (For reference, I have probably tried on a good 15 or so different pairs of shorts in the last couple months). The chamois is pretty thick though, and I've been looking for thinner chamois, so I ended up returning them. Otherwise I think they are great shorts and I wish ALL Pearl Izumi women's shorts were constructed in the same or similar way.
