I bought these because I already have a pair of the RPM knickers that I like. The shorts are made from the same fabric & have the same chamois as the knickers, which is great. However, the knickers have a drawstring waist that sits at the normal waistline, while the shorts have an elastic waist with a dip in the front. I don't really like that dip, which drops the shorts waist below my belly button, and makes it feel like the shorts are creeping down. They are otherwise quite comfortable for riding.
