Bests & Worsts Reviews from Amazon

Admittedly I was frustrated looking for a helmet that would fit my 2 year old. I did not like the helmets found at local stores due to the 'elastic back' feature. Even with the 1+ sizing the helmet could easily shift. I was dissapointed that there is no actual size in the description so here you go. -SIZING ESTIMATE- My Daughter is almost 2, her head (circumference) measures almost 19 inches (80th percentile if that helps you with reference). I gambled on this helmet as I had no reference to size and when I was able to put it on her head I can tell you that 19" is the small size of what this helmet can accommodate. I didn't have it quite dialed down to the smallest size but when I took it off I was very close to the smallest it could go. I LOVE that it fits securely without being crooked on her head. As for the largest it can go, the dial feature offers more growth than the actual helmet itself. The inside of the helmet measures almost 21" which will be just above the largest part of the head. My best GUESS would be no larger than 22" and that will be tight (Most helmets only allow for 1 and a half inch variance, but I have seen up to 2") The dial feature was a little lower than I would like, but it does not dig into her neck and I am sure as she grows it will be in the right spot for her at 3 years old since it recommends that age anyways. My suggestion to Schwinn - include actual head measurements with the description. Equestrian riding helmets ALL do and it makes purchasing a helmet less stressful. On a superficial note - My helmet did not have the yellow tape sealant (it was pink) and I liked it even more. It also does not look giant even though she still can grow into it. I am more than happy with my purchase! Hope this helps!
