With the Castelli Entrata Bibtight, riding outdoors throughout the cold days of fall and winter is a task we are more than ready to conquer. The Thermoflex fabric offers exceptional warmth and comfort, while the KISS Air2 Donna seat pad provides the necessary cushioning to keep us riding for hours without complaints. Castelli added easy-to-use ankle zippers for easy on and off, and a reflective panel below the knee helps keep us seen in low-light conditions.
