This women's specific summer weight cycling baselayer is designed to keep you cool and comfortable even on hot days. Transfer fabric facilitates the evaporative process by rapidly moving moisture away from your skin to outer layers. In back, mesh panels maximize ventilation. Patented anatomic speed sleeve anatomic construction hugs the contours of your shoulders, providing a second-skin fit when in the bent-over riding positing. Wear this short sleeve baselayer under a short sleeve jersey during the heat of summer, and then add it to your cool weather layering system during chillier months.
