Castelli's Evoluzione Bib Shorts challenged our notions of what a sub 100 pair of bibs could be. By including its famed KISS3 chamois, and the ultra wicking ProDry2Strati fabric, Castelli pretty much had this one won before anyone else had their lead outs sorted. Not content to stop at fabrics and chamois, though, the Evoluzione is also cut from 8 different panels of fabric to ensure a precise fit. These panels are then sewn together with a dual needle stitch for durability. Castelli finishes off the job with molded in silicone leg grippers to keep the shorts in place and comfortable.
