The Zero RH+ PW DrySkin Partial Bonded Men's Bib Shorts are designed for unrestricted warm-weather cycling. In addition to keeping you exceedingly dry through the use of DrySkin material, the cut and construction have been designed to allow these shorts to move with you, enhancing your comfort on long rides.As the name implies, the DrySkin material is optimized for wicking, helping it pull moisture away from your body and letting it evaporate quickly. The Partial Bonded designation hints at the fact that along the seams which see the greatest degree of motion, Zero RH+ has opted to bond the fabrics together, rather than stitching them. This minimizes the pulling that can happen at sewn seams, which are less stretchy than the adjacent fabric. The remainder of the seams are flat stitched and low-profile, helping to fight chafing. The raw hem edges are low profile, and the leg hems are backed with a silicone gripper, to keep them from riding up. For the insert, these shorts get Zero RH+'s PowerLogic Man chamois. This insert uses three different densities of foam, selectively placed to best distribute pressure, thereby enhancing your comfort. It's seamless, helping to reduce chafing--a characteristic that's bolstered by its perforated, quick-drying design. This low-bulk chamois has been designed to provide maximum comfort for long rides, without the volume typically associated with long-distance inserts.The Zero RH+ PW DrySkin Partial Bonded Men's Bib Shorts are available in five sizes, from Small, to XX-Large, and in the colors Black, Black/orange, Black/green/lime, and White/black.
