About the original
The Castelli Cycling Bib Shorts are road-race bibs constructed in Italy from a multi-panel Lycra chassis with a body-mapped compression fit, flat-lock stitching, elastic mesh suspenders, and Castelli's Progetto X2 Air Seamless chamois engineered with variable-density foam to support long time in the saddle. Castelli is the cycling-apparel label inside Cannondale-Castelli group Manifattura Valcismon, tracing its origins to a Milan tailor named Vittore Gianni in 1876. The brand supplies the full kit for multiple WorldTour teams and has produced bibs for professional riders from Gianni Motta through the current Soudal Quick-Step roster. The SS25 Supreme collab carries SpongeBob SquarePants graphics as a three-way drop with Nickelodeon.
About Castelli
Castelli is an Italian cycling apparel manufacturer tracing its origins to an 1876 Milan tailoring shop run by Vittore Gianni, which clothed football clubs including Milan and Juventus and cyclists including Alfredo Binda. Armando Castelli joined in 1935 and bought the business, supplying Gino Bartali, Fausto Coppi, and Jacques Anquetil. In 1974 his son Maurizio Castelli founded the current company under the scorpion logo, and in 1977 introduced Lycra to cycling shorts, a first in the sport. Castelli now outfits UCI WorldTour teams including Soudal Quick-Step and produces the Gabba jersey line. Supreme has released co-branded Castelli cycling apparel.
