These shorts fit well, meaning snug, to keep my male parts from shifting, rubbing, or chafing. They have the X-2 pad chamois. It looks thin, but it works well.
Good quality, castelli run a little small so consider going up one size. I am a little on the thin side so castelli fits me very good and comfortable. The little decals on the legs may come off after repeated use, its the only flaw I can find, otherwise a very good short.
Very Good Shorts--pricey, but good looking and comfortable
Endurance MTB events. Only complaint, cosmetic. The scorpion insignia is starting to peel off of the shorts a bit. Little soon for the amount of wear they have had.
Already an owner of both Body Paint and Aero Free bibs I picked up a pair of Aero Race Shorts as well. As with the bibs, love these shorts. While I have read in various places Castelli fits small they fit pretty true to size for me - at 5'11' and 180lbs I wear a size medium. They are fairly compressive...if you're not a fan of that go for the Body Paint.s As someone how does a lot of training indoors I like the short option as they tend to hold in less sweat vs bibs.
