MIPS stands for Multi-directional Impact Protection System. It is a low-friction layer inside the helmet that allows the helmet to rotate slightly on impact, reducing rotational forces on the brain during angled impacts.
A helmet should sit level on your head, about two finger-widths above your eyebrows. The straps should form a V around your ears, and the chin strap should be snug enough to allow only one finger to fit between the strap and your chin. It should not move when you shake your head.
Replace your helmet after any crash, even if no damage is visible. Also replace it every 3-5 years due to material degradation from UV light, sweat, and temperature changes. Check for cracks, frayed straps, or loose fit.
All helmets sold in the US must meet CPSC safety standards. More expensive helmets often have additional features like MIPS, better ventilation, lighter weight, and more comfortable fit systems, but they are not necessarily safer in a crash. The best helmet is one that fits well and you will wear consistently.
Look for helmets with MIPS or similar rotational impact protection. Ensure the helmet meets CPSC or ASTM standards. Additional features like extended rear coverage or a reinforced shell can offer extra protection.
A helmet must fit snugly without pressure points. Adjustable fit systems like Roc Loc or Float Fit allow customization. Check the weight and ventilation, especially if you ride in hot conditions or for long durations.
Choose a helmet designed for your type of riding: road helmets are lightweight and aerodynamic, mountain helmets have visors and more coverage, and commuter helmets often include features like integrated lights or a more casual look.
| Feature | Why it matters |
|---|---|
| MIPS Protection | MIPS reduces rotational forces in angled impacts, significantly lowering the risk of brain injury. It is a key safety feature in modern helmets. |
| Ventilation | Good ventilation keeps you cool and comfortable, especially on long rides or in hot weather. Look for helmets with multiple vents and internal channeling. |
| Fit System | An adjustable fit system ensures a secure and comfortable fit. Systems like Roc Loc or Float Fit allow micro-adjustments for a personalized feel. |
| Weight | A lighter helmet reduces neck fatigue and feels more comfortable on long rides. Premium helmets often weigh under 250 grams, while budget models may exceed 350 grams. |
