Reima has been offering a complete SunProof collection for summer since 2011. Since then, the Rantsu hat from the Reima Originals collection has been protecting little heads from sunstroke with a UV protection factor of 50+. This perfectly designed sun hat protects your child's sensitive skin on both the face and neck. With the quick fastening and ties, the hat stays securely in place even during a diving course and won't get lost in the wind.
