Chin pads & Anti-Pinch Pads:We have designed two different pads specifically for children. The anti-clip pad is on top of the buckle, which can isolate the clip from contact with the face, so you never have to worry about your child getting clipped again. The chin pad is a soft fabric material that wraps around the chin strap and prevents the nylon strap from rubbing against your child's chin.
