Frequently Asked Questions
Do any of these helmets include MIPS?
None of the three products in this comparison advertise MIPS. If MIPS rotational protection is a priority, look for helmets that explicitly list MIPS or similar rotational systems in their product features.
How should I size these helmets?
Measure your head circumference around about 1 cm above the ears and compare to the size ranges listed in the product features. For kids, allow room for growth but ensure a snug, wobble-free fit — adjustable pads or a dial help fine-tune it.
Can I clean the liners and straps?
Yes — CELOID highlights washable breathable liners, and most helmets allow spot cleaning of straps and removable pads. Avoid machine washing the shell and follow the manufacturer's care notes to preserve fit and foam integrity.
