The Sorpasso Bibtight is our best winter tight because of its exceptionally wide comfort range and the amazing fit. And both of these features come from the combination of our Thermoflex Core2 fabric and our standard fleecy Themoflex.
The Core2 fabric is made with a hollow-core polyester yarn on the inside and a nylon outer face, which together provide excellent insulation for cold temperatures along with better wicking to keep you comfortable when it's not so cold. This fabric offers some wind protection but is somewhat limited in stretch, and that's where the extremely stretchy Thermoflex fabric comes in.
The overall effect is a tight that offers optimal compression and seems to just move with you.
Castelli have a typically snug "Euro"-style race-ready fit.
If you're between two sizes, or you prefer a more relaxed fit, we recommend you go up a size.
Please use the table below as an indication of actual fit and don't be concerned if it suggests a larger size than you usually take in other brands.
