Review on Dinosaur Toddler Helmet 3+ and Child Helmet 5+ by Raskullz by Nathan Jones

Great concept but the helmet didn't fit. The size says 3 and up, please be different. My son is 6 and I ordered him because we have a Shark helmet from the same brand and it's great! But now my son loves dinosaurs so we thought it would be a nice surprise. This clearly didn't suit him as there was a decent gap around his head. The helmet kept moving and he leaned more and more to the side. It went up and onto his forehead. No matter how much we adjust it, it won't fit snugly or stay in place, which is too risky for me. My son is very active and skates off the big ramps and pools at the skate park, so we need reliability. We have a Raskullz shark helmet and it fits him much better. (Photos are attached for reference) Looking at the size of each helmet, I noticed the dinosaur was small. His shark that fits perfectly with the same brand is the XS. So I'm confused because if this one is small and suitable for ages 3+ what are the recommendations for the XS? I would say this dinosaur helmet is the next step up from 3+ unless your kid has a bigger head. The manufacturer is excellent, the quality is excellent. The fit was bad. So now I have an upset toddler because I have to send it back.
