The Infinity Split shorts from Pearl Izumi feature a split hem to enhance mobility. Moisture-wicking, quick-drying outer shorts provide lightweight comfort, and they protect skin from harmful UV rays with a UPF rating of 50+. Liner shorts blend standard polyester with Minerale(TM) polyester to increase dry time and reduce odors. Minerale fabric embeds crushed volcanic minerals in the polyester fibers for excellent wicking, evaporative cooling and odor resistance. Simply wash the shorts to renew their performance qualities; Minerale technology will not wash off or wear out. Elastic waistband with drawcord secures fit. Rear zippered pocket stores extras. The semifitted Pearl Izumi Infinity shorts are not too tight and not too loose.
