how to wear a helmet correctly

1. Choose the right helmet - Use a helmet certified for your activity (e.g., CPSC for cycling, ASTM/CE for sports, DOT/Snell for motorcycle). - Pick one that fits your head shape (round vs. oval). 2. Size and positioning - Measure head circumference above the eyebrows; choose the matching size. - Place helmet level on your head — it should sit low on the forehead (about 1–2 finger-widths above the eyebrows) and not tip back or forward. 3. Adjust the fit - Tighten the internal fit system (dial or pads) so the helmet is snug but comfortable; it should not move independently when you shake your head. - Side straps form a “V” under each ear; the sliders should rest just below the earlobes. - Buckle the chin strap and tighten so only one or two fingers can fit between strap and chin. 4. Check retention and coverage - With straps fastened, open your mouth wide — the helmet should pull down slightly on your head. - Try to move the helmet front-to-back and side-to-side; only minimal movement is acceptable. 5. Maintenance and replacement - Replace helmet after any significant impact, even if damage isn’t obvious. - Follow manufacturer instructions for cleaning and storage; replace after recommended service life (usually 3–10 years).
