Pullover this lightweight, technical layer for optimal coverage during cool-weather runs. The updated design for 2013 features body-mapped construction and FlashDry fibers to accelerate drying time and regulate body temperature. The durable knit body is body mapped with knit panels down the center back and neck, under the arms, and down the sides for breathability where you need it most. A quarter-zip neck provides extra coverage when fully zipped, or ventilates the core when unzipped. Easy-access chest pocket secures energy gels or car keys. Thumb holes at the base of each sleeve provide greater coverage during forward-motion.
