In 2003, 25% of skiers and snowboarders hit the slopes wearing helmets. Nine years later, that number was up to 70% with resorts in Switzerland reporting that 95% of its children wear helmets while skiing or snowboarding. One of the key factors that changed over the years is that ski helmets are increasingly more comfortable, warmer and designed to have an incredible fit and feel…if they fit properly, that is.

A helmet that doesn’t fit properly won’t have many benefits. Also, if a helmet isn’t comfortable, you’re probably not going to want to wear it anyway, which then gives you zero benefits.

Here’s a three-step guide to ensuring that you’re heading out to the mountain with the best fitting, most comfortable helmet out there.

Step 1: What You Need to Measure Your Head

The ideal tool is going to be a fabric tape measure but if that’s not available, look online for a printable tape measure.

The other option is using string and a ruler, or measuring tape.

Step 2: The Measuring of the Circumference of Your Head

Place the tape measure just above the eyebrows making sure that any hair on the forehead is out of the way.

Take a lap around your head to the point of overlap.

Now you have the circumference of your head.

Step 3: Finding the Right Helmet Size

As easy as this sounds, it might actually take a little work to find the right size. Each company tends to skew their helmet size a little. One company’s medium may bleed into another company’s large.

Don’t let this worry you too much though. Simply, check out the sizing charts for the helmet that you want to get. This will allow you to determine the right size for that brand. Many manufacturers make helmets that are adjustable so you can customize your helmet even more once you get it home!

With your correct-fitting helmet, you’ll be able to conquer the mountain comfortably and with the protection to help prevent any serious injury for when you take a spill.
