Castelli Sorpasso 2 Bibtight

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. For 2017 we’ve updated the design of the tight and
given it a lumbar support panel that further improves the fit. #4517516-010
