So, I bought two of these in the Pink shade. Very light weight helmets! I thought they sent me the wrong item before I opened the box due to it being so light. I absolutely LOVE them! My daughter is almost 2. I got her the small, and the large for myself. (22f) They come with an extra strap to hold up extra strap after adjustment for under the chin. It’s a comfortable material. A dust/storage bag is also included. The back of the helmet has a knob which you turn to adjust how snug the helmet is. (It comes into the helmet to fit snug around the back of the skull) which is great! I have a smaller head, and I was SO nervous this helmet wouldn’t fit my child. They both fit perfectly and are comfortable!
