Buying Guide
When selecting a road helmet, prioritize safety tech, fit, ventilation, and weight. MIPS can reduce rotational forces in certain impacts, but a properly sized helmet with a secure strap system is essential for real-world protection. Consider your typical riding conditions—summer climbs, windy descents, or all-season training—when evaluating vent count and shell construction.
- MIPS vs. non-MIPS: evaluate the trade-offs between protective tech and weight.
- Fit and sizing: some helmets use universal sizing, others have dial adjustments or multiple shell sizes.
- Ventilation and weight: more vents usually improve cooling but may affect weight; balance with riding needs.
- Shell construction: in-mold designs are common for light weight and strength; some microshells offer durability in rough conditions.
- Visor compatibility and accessories: consider removable visors and eyewear integration if you wear sunglasses or glasses.
- Certifications: look for CPSC (U.S.), EN 1078 (EU), or AS/NZS 2063 where applicable.
- Warranty and returns: confirm terms to ensure confidence in sizing and fit.
- Practical buying tips: for variable weather, look for removable liners or versatile ventilation features; compare vent counts, weight, and adjustability.
