Chiller Spider Helmet
Looking for a rad new cycling buddy? Our Chiller Spider helmet is the coolest bike companion on any race track, skate park or adventure! Stay chilled, safe and rad on every ride.
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.
