When your young rider is dedicated to the dirt, you need gear that keeps pace with their skill set. The Smith Wilder Jr. mountain bike helmet combines the enhanced angle impact protection of Mips® with a lightweight, ventilated design just like Smith's adult helmets. 21 fixed vents keep the air flowing as kids bomb down their favorite trails. An adjustable dial fit system adjusts around the head with the turn of a dial to get the right fit every time. There's a built-in visor to cut glare and integrated sunglasses storage, so kids can stow their glasses just like mom or dad.
