The Castelli Prima Woman’s Bib-short may be an entry-level short, but Castelli didn’t compromise anything for comfort and performance. The woman’s specific KISS Air² seat pad has been made more breathable, hence the name “air.” The air creates a space for more air to circulate. By allowing more air to circulate the seat pad stays dry and the rider’s seat won’t overheat. The seat pad is now even softer which means even more comfortable on those longer rides. The fabric used in the bib-short has been upgraded to the new Pro Dry Soft which has a smooth matte finish that cools the skin and dries instantly. The Giro³ elastic has the grip woven into the fabric which makes it softer against skin while never losing the grip. Mesh bib straps keep the shorts in place with a soft, lightweight material. Rear reflective panels improve visibility on early morning or overcast training rides and races.
