The Inferno is the premium-level race short made specifically for hot weather. Designed to keep you as cool as possible, it has a perforated fabric on the side panels and mesh-like GRID Air leg bands, and the fabric on the front of the short actually includes titanium dioxide (the active ingredient in sunscreen) to help reflect UV rays and keep you cool. You see the professionals from Team Sky wearing these shorts in all kind of conditions because it also happens to fit extremelly well and is one of the most comfortable shorts they have ever worn.
Castelli traces its roots back to a fine tailor Vittore Gianni in the heart of Milan, founded in 1876. The first cycling clothing was made in the 1910´s for the world champion and five-time Giro champion Alfredo Binda.
