No matter what adventure your burrito butt is having on their Strider Bike, safety is key. The Strider Splash Helmet has easy-to-use features, including a dial system for easy, on-the-go adjustability. We even made a no-pinch buckle and padded chin guard, so those chubby cheeks have a snug, secure fit. With an internal wrap-around padded sweatband and 14 large air vents to keep them cool, your rider will stay calm, safe, and stylish. Fits heads 21-23 inches in circumference.
