Castelli Premio Black BibshortPremium PremioThe Premio are Castelli's new top of the line bibshorts engineered to be the ultimate long-distance bibshort solution that doesn't sacrifice speed or durability in the process. Featuring an all new woven fabric that weighs a whopping 30% less than comparable knit fabrics, you can be sure that you're getting nothing less than the best. Castelli's new fabric doesn't require a multiple seam and panel design which allows for increased comfort and fit. An all new perforated back panel design allows for increased airflow and ventilation while the bib straps have a flat design that doesn't bunch up around the shoulders. Castelli even engineered and optimized the Premio bibshorts to function in 57Adeg-100AdegF temperatures which gives you the option to use these for the majority of the year. Minimal gripper elastic pads built into the legs keep the bibshorts locked in place without the need for additional gripper pads. The Progetto X2 Air Seamless pad allows you to ride all day long with its two component design. The layer that contacts your skin, the Skin Care Layer, prevents any rubbing or bunching while the Cushioning Layer underneath is made of two foam densities that breath extremely well while also being optimized to provide an incredible level of comfort directly below your ischia and perineum bones. The Premio bibshorts truly are the ultimate option for long distance riding that don't cut any corners or sacrifice any features in the pursuit of comfort and support.
