Buyer Questions
What is MIPS and do I need it?
MIPS (Multi-directional Impact Protection System) is a slip-plane liner that reduces rotational forces in angled impacts — safety experts recommend it; the cost premium is typically $20–$30.
How often should I replace a bike helmet?
Replace immediately after any impact, and replace every 3–5 years regardless — UV exposure and use degrade the foam even without visible damage.
Do bike helmet sizes vary by brand?
Yes — always measure your head circumference in centimeters and check each brand's size chart; a helmet that doesn't fit offers much less protection.
Are expensive bike helmets safer?
All CPSC-certified helmets meet the same minimum safety standard; expensive helmets add MIPS, better ventilation, and lighter weight — not necessarily more crash protection at the baseline.
