I loved these for the first 20 miles of a 40 mile ride, but about half way through the seam edge of the chamois started to rub and caused huge problems by the time I got home. They need to consider different fabrics or edge construction, because otherwise these would be fantastic. They stayed put with the leg grippers and fit very well. The chamois is the perfect thickness and they were comfortable. Too bad I'll only be able to wear them on short rides.
