Designed specifically for racing, these Castelli women's bib shorts are a game - changer. Usually, our women's apparel is crafted from scratch for female riders, but the Free Aero 4 W Bibshort is engineered from the ground up for the race track. The minimalist design is a win - win, offering both excellent aerodynamics and comfort. Whether you're training for hours or competing on race day, you'll find these to be some of the most comfortable shorts ever. An upgrade from last year's best - seller, these bib shorts come with a new leg gripper. It has a lie - flat raw - cut edge and vertical silicone stripes to hold it in place without limiting stretch. The new fabric not only allows for high - quality custom team prints, just like what Team INEOS will use in 2019, but also gives a great look. We've refined the seams for a better fit and a more flattering appearance on the body. The bib straps are re - engineered with new fabrics and construction, staying cooler, lying flatter, and being more durable. And let's not forget the updated Progetto X2 Air Seamless seat pad with the softest surface fabric you've ever felt in a seat pad.


Using these Castelli bib shorts is easy. Simply put them on like you would any regular shorts, making sure the leg grippers fit snugly around your thighs and the bib straps sit comfortably over your shoulders. For the best results, adjust the straps to your preferred tightness. When it comes to care, it's best to wash them in cold water with a mild detergent. Avoid using fabric softeners as they can damage the silicone stripes on the leg grippers. Hang them to dry instead of putting them in the dryer, as high heat can shrink the fabric and affect the shape of the shorts. Also, be careful when handling the seat pad, as it's made of a soft fabric that can snag easily. If you're planning to get a custom print on your shorts, make sure to follow the specific instructions provided by the printing service.
