The Trek Performance Lab is where we crunch the numbers and use in-house pressure-mapping to ensure the chamois’ shape, density, and placement is exactly how and where we want it to be.
Lightweight bib straps offer a comfortable, stay-put fit so you can focus on the road ahead and not pressure points or overexposure while you're riding.
The bib straps are connected to ultra-breathable mesh panels that are designed to increase ventilation and help keep you dry and comfortable throughout your entire ride.
PinchLess leg construction allows the shorts to follow your every move while pedaling, and ultra-comfortable leg bands stay put without digging in.
Cycling garments are designed to provide function and performance, but they need to fit well to work well. Since not all apparel fits the same, reference our sizing guides below to see how Bontrager apparel and accessories are intended to fit, and find the perfect size and cut for your riding needs.
