- Familiarity: I've used it several times
bought these purely for training in, specifically run and swim just to be used to the feel. I have the single piece Castelli suit so this helps with the fee to it. Typically Castelli fit, more euro sizing so a little small. I'm 5'7" 130 lbs and took a small. They leg length is on the short side, compared to how bike shorts are running anymore.
