When to Replace Your Helmet

Your helmet has a finite lifespan. Knowing when to retire it can literally save your life. Here are the definitive replacement triggers.

After Any Crash

Replace your helmet immediately after any crash, even a low-speed tip-over. The EPS (expanded polystyrene) liner is engineered to crush on impact — a one-time energy absorption event. Once compressed, it cannot perform again. External shell damage may be invisible while internal liner compression is severe. Do not trust a crashed helmet regardless of its appearance.

After a Significant Drop

Dropping a helmet from counter height (roughly three feet) with a head-weight object inside can compress the EPS liner. An empty helmet dropped on carpet is less concerning than a loaded helmet dropped on concrete. When in doubt, contact the manufacturer — many offer inspection programs.

Five-Year Age Limit

Most manufacturers recommend replacing your helmet every five years from the date of purchase, regardless of visible condition. The EPS liner degrades from cumulative exposure to heat, sweat, hair oils, UV radiation, and atmospheric conditions. This degradation is invisible but reduces the liner's ability to absorb energy in a crash.

The manufacture date is typically printed on a label under the comfort liner or on the chin strap. If you cannot find the date, the helmet is old enough to replace.

Degraded Fit

If your helmet feels noticeably looser than when you bought it — even after accounting for normal break-in — the interior foam has compressed beyond its useful range. A loose helmet can shift during impact, reducing its protective coverage. Time for a new one.

Visible Damage

Cracks in the outer shell, frayed or stretched chin straps, a visor that no longer seals properly, or EPS liner visible through a worn comfort liner are all signs the helmet needs replacement.
