Pearl Izumi's Attack Bib Shorts use moisture managing Select fabric mated to Direct Vent mesh uppers to keep you spinning comfortably all day. When the final attack does come, you'll be still be fresh and ready to go, whether you're responding to or initiating the move. The eight panel, ergonomic design means you fit into the shorts rather than the shorts deforming to fit you, and the folded, Select Transfer leg bands are printed with silicone grip to keep the legs in place without the restrictive pinch of elastics. The Attacks include a Race 3D Chamois, which is a comfort oriented pad for riders who get in anywhere from two to seven days of riding in a week. Like the shorts themselves, the Race 3D is pre shaped to fit the contours of your body with slightly denser padding than the P. R. O. Seamless Chamois to offer more support. The advanced Pearl Izumi four way stretch technology will keep the insert moving with you and wicking sweat so you won't have to worry about irritating, saddle sore inducing friction or moisture.
