Wrapping your lower body in lightly graduated compression with Thunderbike Power Lycra, the Santini Men’s Ace Bib Short maintains a high degree of muscle support as you rack up mile after blissful mile in balmy weather. Elasticized cuffs remain securely in place with silicone grippers, so you won’t have to stop and constantly adjust the leg cuffs. These supportive bibs not only support hard-working muscle groups, but they absorb harsh vibration and eliminate chafing with the GT EVO chamois. This chamois is comprised of a perforated silicone gel core buried under plush foam padding. The surface of the chamois uses shaped microfiber fabric that won’t create irritation or chafing issues, even while it’s rubbing against the most sensitive areas of your body.
