Take a step back in time to the land of the giants with this brand new Jurassic fun park helmet! Whether it’s the fish-chasing Plesiosaurus, the marshmallow roasting Triceratops or the sabre-toothed rat scaring the Dilophosaurus, these fearsome, swashbuckling creatures will make you smile and will be there to keep you safe on your adventures.
If your child's head measures 53.9cm we would strongly recommend you go for the S size. In our experience the S size will be a good fit. Don't be tempted to buy a helmet that they will grow into as it won't offer full protection. A 5 year old's head typically grows ~ 0.5cm in circumference in a year.
