A helmet is the one piece of gear that can save your life. Modern helmets are lightweight, well-ventilated, and comfortable enough to forget you are wearing one. But only if they fit correctly.
Fit is everything
A helmet should sit level on your head, covering your forehead. The straps form a V shape under each ear and the buckle sits snug under your chin with room for one finger. It should not rock forward or backward when you push it. Try multiple brands as head shapes vary.
Safety technologies
- MIPS (Multi-directional Impact Protection System): a slip plane inside the helmet that reduces rotational forces during angled impacts.
- WaveCel: a collapsible cellular structure that absorbs both linear and rotational energy.
- SPIN (Shearing Pads INside): silicone pads that allow the helmet to rotate slightly on impact.
- All certified helmets meet minimum safety standards. MIPS and similar technologies add protection against rotational injuries.
When to replace
Replace your helmet after any significant impact, even if there is no visible damage. The foam may be compressed internally. Also replace after 3 to 5 years of regular use as UV exposure and sweat degrade materials over time.
