Types of Bike Helmets 

• Recreational: An economical choice with impact protection for casual riding 

• Mountain bike: Extra rear head coverage for off-road and rugged trails with ventilation options 

• Road bike: Lightweight, aerodynamic and highly ventilated 

Fit Tips 

• Measure your head’s circumference by wrapping a flexible measuring tape around the largest portion of your head (or use a piece of string, then measure its length). 

• Check brand sizing charts for your head circumference. 

• Aim for a snug fit but not too tight. If between sizes, go with the smaller size. 

Added Protection 

Look for technologies that reduce rotational forces during a crash, like Mips, WaveCel or KinetiCore. 

Features 

• Vents: More vents improve airflow and reduce weight.

• Visor/brim: Keeps the sun out of your eyes; common on mountain bike helmets. 

• Chin bars: Extra protection for downhill mountain biking or racing. 

How to size a ski or snowboard helmet

• Helmets should fit comfortably and sit correctly on your head for the best protection.

• If possible, try helmets on in-person at your local REI store to find one that feels most comfortable.
• To find your size, measure your head circumference. Wrap a tape measure around your head, just above the ears and about 1" above your eyebrows. Consult the sizing chart for different brands to find the right size.

Key features to consider:

• Vents let cool air in and warm sweaty air out. Adjustable levers let you fine-tune airflow on the go.
• Liners: Customize warmth by adjusting liners or ear pads. Some removable liners can be washed.
• Audio: Helmets with built-in speakers let you listen to music.
• Googles compatibility: Make sure the helmet fits snugly to the top of the goggles, but not so low that it hinders vision or pushes down the goggles. There should be no gap between the top of your goggles and the helmet.

Happy riding!
