Ideal sun protection for kids all summer long, whether at the pool, lake, river beach or backyard. Easier to put on than sunscreen, the NRS Hydrosilk long sleeve shirt guards a child's upper body from the sun's harmful rays with UPF 50 protection. Great for the pool, the beach, the river or the back yard. Quick drying 8 oz nylonspandex blend blocks harmful rays while wicking moisture away from the body, keeping kids cool, happy and sunburn free. Much easier than having to keep applying sunscreen! A silky finish inside and out feels great against the skin, making it easy to keep kids in this shirt for a full day's activities. The Youth HydroSilk shirt also makes an excellent moisture wicking base layer in cooler weather. Snug fitting and lightweight, it fits easily under other layers of outdoor clothing.
