Astronaut Helmet

4.9
Rated 4.9 out of 5 stars
242 Reviews

Strap in and buckle up as you get ready to go and explore! Featuring a space badge, microphone, visor and breathing apparatus design, whether you’re heading to the park, a new trail or a new planet (!), you will look the part with the brand new Astronaut helmet.

Important

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.

Seriously fun lids for kids!

A helmet is only as good as its fit. Maximum protection demands a snug, well-aligned fit that is comfortable, yet secure. This is why Hornit helmets feature a fully adjustable ring adjuster - rotate right to tighten and left to loosen. Our three-way adjustable chin strap and the strong and secure buckle ensures the helmet always stays in place. Removable soft foam allows further flexibility for size and fit during growing years. Made from durable, weather-proof plastic, Hornit helmets protect your kids as they brave the rain, snow, and wind. Eleven air vents on each helmet ensure even air flow to keep them cool and comfortable. The rear safety light alerts distracted drivers or pedestrians to your child's presence. Combining style and safety, Hornit helmets come in a range of fun designs.

Frequently Asked Questions

Our small helmet fits head circumferences between 48-53cm. Our medium helmets fit head circumferences between 54-58cm. The measurement (in cm) refers to the circumference around the largest part of the rider's head (approximately 1cm above the rider's eyebrows). Our helmets generally fit children aged 3+. This isn't a rule though – actual sizing is critical - so please measure up!

Yes! We have a ring adjuster at the back of the helmet (with an integrated LED light) which tightens and loosens to ensure the helmet fits snuggly to you're the rider's head. The straps that clip under the chin are also adjustable. The ring adjuster should be tightened until the fit is firm, but comfortable and the chin strap should fit snugly under the chin.

No. If the helmet has suffered an impact (even if there is no visible damage), or when it shows obvious signs of wear and tear, you should discard and replace it. It is recommended that helmets are replaced after 4-5 years after initial use or within 8 years of production.

If your LED light at the back of the helmet has stopped working, then it almost certainly needs new batteries. Unscrew the two small screws and put in 2 new AG3 batteries or 1 new CR2032 battery depending on which LED you have. If this doesn't fix the problem, then contact us and we will help!

    Colourful helmet that , most importantly, meets safety standards. Flashing light improves visibility and is a big hit with my granddaughter. Adjustable to ensure fit.
