The FUJITRAIL™ TOP is designed for trail runners who want to stay cool and dry while running off the beaten track. It features a half-zip design for added breathability when needed. Sweat-resistant mesh fabric on the back and sleeves helps keep the garment dry and lightweight, both during and after your run. We also incorporate anti-odor technology in key areas to keep the top fresh for longer. Designed by the ASICS Institute of Sports Science in Japan, the FUJITRAIL™ TOP also features a convenient back pocket for storing your jacket and essentials. Finally, reflective elements on the front and back are strategically placed to increase your visibility in low-light conditions.
