Castelli Entrata Bib Tight Thermoflex fabric makes the Castelli Entrata Bib Tight perfect for winter rides, keeping your muscles and joints warm and well protected from the elements. The tight is held in place by breathable mesh bib straps, and ankle zippers make it easy to pull on and remove. A KISS Air2 seat pad, the choice of many pro cyclists, serves to protect you hour after hour in the saddle, cushioning and absorbing shocks from the road. The Entrata is finished with reflective details for extra visibility in low light.
