Buying Guide
Fit and Sizing
Proper fit is essential for optimal protection and comfort. Look for helmets with adjustable fit systems (dial or cradle) and refer to each brand’s sizing chart. Measure head circumference at the widest point above the eyebrows and around the back of the head. If you’re between sizes, choose the larger size and use the fit system to secure a snug, even feel that doesn’t compress your temples.
Safety Technologies
Gravel helmets commonly feature rotational protection systems (like WG11 or MIPS), impact-absorbing materials (EPS), and multi-density shells. Evaluate which technologies matter most for you: rotational impact protection, extended shell coverage, or Koroyd-style energy absorption. In mixed terrain, dependable protection against angular impacts can be crucial on rough descents.
Ventilation and Comfort
Ventilation quality affects comfort on long climbs and warm days. Consider the number and placement of vents, internal channels, and whether the helmet’s lining helps wick moisture. Some models emphasize front-to-back airflow or have removable pads for washing, which can extend helmet life and maintain comfort.
Weight, Aerodynamics, and Build
Weight and aerodynamics influence agility and fatigue over long races or rides. Ultralight designs favor speed and endurance, but sometimes extra shell coverage adds weight. Decide whether you prefer a lighter helmet with simpler ventilation or a more protective shell with extended coverage for gravel routes.
Visors, Goggles, and Accessories
Visors and compatibility with goggles are important for gravel, where sun glare and dust are common. Ensure the helmet supports the visor style you want and check for goggle clips or storage options. RECCO reflectors and other locating aids are useful for safety in remote areas.
Maintenance and Longevity
Regular cleaning of pads and shells extends helmet life. Follow the manufacturer’s care instructions, avoid exposing the helmet to high heat, and replace after impact or if the shell shows cracks or deformation. Proper storage away from direct sunlight helps preserve materials and color.
