Castelli Swimming

The Castelli Core Spr-oly suit is a short-distance race suit for speed and comfort. It is made of Endurance Evolution fabric which is lightweight but supportive and has a close-cut top with longer legs. The suit has reduced seaming for faster swims, a rear envelope pocket which stays closed in the water but makes it easy to carry a gel and a fleece seat liner that smooths out the bike ride but disappears on the run. Tip: keep in mind that the Castelli clothing fits smaller than normal.
