Comfort and fit
When trying to find the correct helmet model and size, it’s important to consider everything from the overall helmet shape to its retention systems and straps. A poor fit isn’t just uncomfortable, it can compromise safety. The first thing you need to know is your head circumference. You can find this by wrapping a flexible tape measure around your head about 2cm above your eyebrows. Or you can wrap a string around your head and measure it with a yardstick. Once you have the right size, be sure to properly adjust the chin straps and buckle, along with the adjustment dial if it has one (usually located in the rear of the helmet).
Conditions and terrain
Are you looking for added warmth in high alpine terrain? Or do you spend more time trekking uphill for backcountry runs? Are you often exposed to winter storms? Or do you prefer warmer, sunny conditions? Different helmets have different features. Some include vents that can be open or closed, a handy option that can protect you from the cold (closed) or prevent you from overheating (open) when temperatures warm up. Some also have detachable ear pads for skiing or snowboarding in warmer spring conditions.
Safety certifications
This is what matters most when choosing a helmet. You can look for certain safety features, including our Mips® safety system and other special functions made for the type of riding you do, but the first step is to make sure the helmet is certified to helmet standards in your country. There are many different standards worldwide, but some of the most common ones include the ASTM F2040 snow helmet certification in the U.S., and the CE EN1077 certification in Europe.
Special features
Modern ski helmets are packed with purpose-built features. These can include adjustable brims, which can help with goggle compatibility. You want to make sure your goggles fit well with your helmet so there’s no gap. Air should be able to flow up through the bottom of the goggles, through the holes on top, and into the helmet brim vents. This will prevent fogging. Other features include adjustable fit systems such as a Boa dial for fine tuning. Many new helmets also have audio compatibility, with interior speakers or small pockets in the ear pads to place aftermarket speakers.
Rotational management
This is the reason Mips exists. We have done the research. We have the data. Studies show that when you crash and hit your head, it’s most often an angled impact. This creates rotational motion, and the brain is very sensitive to this. So, this part is easy: just be sure to pick a helmet that’s equipped with a Mips® safety system, which is intended to help reduce rotational forces to the head when falling at an angled impact.
