"The Bib Liner 4.0 is built for big days and aggressive enduro riding. Worn under any Leatt short or pants, it delivers pro-level comfort, moisture management, and on-body storage—right where you need it. The ultra-breathable, bluesign® approved fabric wicks sweat and dries fast to keep you cool. A premium Italian Elastic Interface chamois supports up to 7 hours of ride time, while four cargo pockets and a dedicated hydration bladder sleeve give you space for tools, snacks, and more. A unique fly opening makes for quick and easy nature breaks. With a skin-tight fit and above-the-knee cut for knee guard compatibility, the Bib Liner 4.0 is your foundation for high-performance days on the bike. "
