Toss on the Sugoi Men's RXS Bib Liner underneath your favorite trail baggies before embarking on spirited rides across alpine ridgelines, moss covered forests, and coastal headlands. Effortlessly integrating with your favorite riding shorts, the RXS Bib Liner remains extremely lightweight and low bulk, meaning it won't get in the way of your trail shredding pursuits. Mesh fabric promotes a well ventilated, supremely cool feel, even on the warmest rides of the year. Perhaps most impressive, the Formula FX chamois softens the sting of pummeling through rocky trails with its high density, vibration dampening relief pads. Four way stretch fabric conforms to your body, eliminating chafing and excess irritation. Plus, it perforated design enables moisture to rapidly evaporate, so you won't feel like you're wearing a wet diaper after hours of rigorous riding. Other trail savvy features include Sugoi's signature leg grippers and built in pockets for storing energy gels and small accessories.
