It's smart to wear a hat in sunny weather! This light children's sun hat is made from stretchy Reima SunProof jersey. It boasts a high UV protection factor 50+, allowing for longer playtime in the sun. A soft visor shields eyes from glare, while the back brim keeps necks out of the sun. The hat has no lining, so it's always comfortable to wear, and because it dries quickly, it's the ideal companion for beach play. Please note: When the fabric is wet or stretched, the protection might decrease. For safe play in the sun, kids should always use sunglasses and have their bare skin areas protected with sunscreen lotion.
