The specialty fabric will help keep your little one cool, dry, and protected from the sun's harmful rays due to UPF 50+ sun protective rating. Prodoh's original also has features similar to Dads fishing shirt such as roll up/button tab sleeves and a vented back overlay with mesh liner. Parents love the Get back here loop located on the rear of collar. It definitely comes in handy during round up time! Prodoh originals are stain resistant, quick drying, sun protective, wrinkle resistant, cute, and comfortable!
