Our S4-R Performance Bib Shorts quickly became our flagship model once they hit the market....and for good reason. They employ one of the best chamois on the planet and they can go all day without you having to worry about being comfortable in the saddle. The chamois is a true endurance pad made for big miles, but it is also engineered with a flattering low profile and multi-density padding that allows you to comfortably move around on the bike no matter what type of riding you do. Our S4R body fabric is a wonder and is incredibly luxe and durable at the same time. Most people notice instantly that these feel different and better than anything they've worn before. We do not like heavy, dense, super-compressive fabrics that trap heat and create uncomfortable, unsafe conditions in sensitive areas so we use a proprietary custom knitted lightweight stretch nylon for our basecloth. For 2019 we've added more stretch and breathability to take these to the next level. The straps on our bibs are as comfy as they come and are soft, anatomically shaped to fit the body, and stretch as far needed to fit almost any size rider. For those looking for a more compressive fit we suggest sizing down. Other features include interior silicone leg grippers, breathable mesh upper, a superior fit that straddles comfort and performance perfectly, and of course our minimalist branding package. It's no wonder we have a hard time keeping these in stock. All are Made in New York City just like everything else we make.
