The ASICS Jaide(R) hoodie offers just the right amount of coverage and UV protection for tough workouts outside. Brushed and heathered polyester offers breathability, air circulation and moisture management, all with an incredible, soft-as-butter feel. Fabric provides UPF 50+ sun protection, shielding skin from harmful ultraviolet rays. You'll run farther without chafing thanks to the flat seams. Thumbholes help keep sleeves in place as you exercise and warm hands. Zippered security pockets works with your media player; locking zipper won't bounce around on run. Reflective highlights increase visibility. Semifitted ASICS Jaide hoodie is not too tight and not too loose.
