Measure around the fullest part of the head, compare that measurement with the selected option, and adjust the retention system before every ride. A helmet should sit level and feel secure without pressure points.

Choose the right setup

Use the size and color selector above to choose the exact available configuration. Re-check fit after adjustments, growth spurts or a significant impact.

Before the first ride

Replace a helmet after a significant impact or visible damage. Before each ride, check the shell, straps and buckle, and make sure the rider is using a correctly fitted helmet.

Frequently Asked Questions

Which head sizes does the White Astronaut helmet cover?

Its actual options are S 46-51 cm and M 52-56 cm. Measure the child first, then check the fitted helmet; the astronaut design does not change how circumference should be chosen.

Will the astronaut helmet be uncomfortable on warm rides?

The product notes confirm 14 vents and insect screens to support airflow. They do not guarantee the child will never feel warm; check fit and comfort during use and take appropriate breaks.

Can I fine-tune the fit after choosing S or M?

Yes. An adjustable fit dial and straps are expressly recorded for this model. Use them according to the instructions to refine a correctly chosen size; they do not make an oversized shell suitable.

Does the insect mesh mean the vents are sealed?

The recorded feature is an insect screen alongside the ventilation openings, intended to allow airflow while screening insects. Inspect it and follow the care instructions rather than removing or modifying the vent system.

Is the White Astronaut helmet sold with matching guards?

Matching wrist, knee and elbow guards are not confirmed as included on this page. Check a protective-gear-set listing or ask XJD if you need a coordinated bundle.
