Designed for high-output riders who live in their baggies but won't compromise on comfort, the Men's PRO Transfer Liner Bib Shorts are built to deliver pro-level performance beneath your outer layers. Whether you're hitting all-day gravel routes or charging backcountry singletrack, this premium liner gives you chamois-equipped support with minimal bulk and maximum breathability. Crafted from ultralight Transfer fabric , this bib liner is designed to wick moisture, promote airflow, and maintain a cool, dry feel against your skin—even under heavy effort and hot temps. The form-fitting design disappears under shorts and keeps everything in place without restriction or bunching. At its core is the PRO Levitate chamois , our most advanced multi-density pad, engineered for friction-free comfort, pressure relief, and vibration absorption over long distances. Whether you're seated for hours on a gravel grind or flowing through techy descents, this chamois delivers consistent, ride-long support. Additional features include drop-in cargo pockets for easy access to snacks or tools, a secure rear lumbar pocket ideal for a base layer stash or hydration, and low-profile silicone leg grippers to prevent riding up under your shell. Pair it with our Summit Shell Shorts for trail-focused comfort, or explore our full line of men's mountain bike shorts for every kind of riding setup.
