The cobalt blue tennis long-sleeved shirt for women and girls with sporty flat seams is made from a soft, breathable microfibre. The stand-up collar design and long sleeves with thumb hole ensure protection and comfort in cool weather. The long sleeve's slim fit, slightly longer back hem and stretchy stretch material provide light compression and muscle support. In summer, the lightweight, high-neck tennis shirt protects its wearer from harmful sun rays with integrated UPF50 UV protection. This functional shirt is one of our new favourites every season!
