Kids are always on the go, and our Coco Plum Everyday Long Sleeve T-Shirt will keep up with them every step of the way. Wear it solo or layered, this wardrobe essential is as flexible as you need it to be. Our exclusive cotton blend with zinc oxide provides UPF 50+ sun protection that won't wash out. The classic design is lightweight and cool for year-round comfort indoors and outdoors. Imbedded into the fibers are over 800 billion ZnO particles, each 1/10,000 the size of a human hair. These tiny ZnO particles cannot be absorbed by the skin, cannot wear or wash off, and safely deflect all UV rays.
