Castelli Sorpasso Bib Knickers

Castelli Sorpasso Bib Knickers. Castelli has taken all their best technologies and packed it into their Sorpasso Bib knickers. Now lighter, warmer and drier than ever, these knickers use Thermoflex Core Due fabric on the inside to trap heat and manage moisture, and Thermoflex fabric on the outside for an incredibly soft feel and even more warmth. Progetto X2 Air chamois gets a boost with improved airflow, faster drying and variable density padding. YKK cam lock ankle zippers are covered in reflective tape for excellent night visibility. Perfect for long training rides in cool to cold weather.
