Full-Face or Open-Face Helmet

First, choose a mtb helmet that suits your style of riding. That is, either a standard open-face mountain bike helmet or a full-face helmet for the more aggressive enduro rider. If you’re not sure whether you should buy a full-face or open-face mountain biking helmet check our post here to help you decide.

Helmet Certification

Secondly, ensure that your choice of helmet is properly safety certified for your particular style of riding. At the very minimum your MTB helmet needs CPSC 1203 certification in the U.S., or CE EN1078 in Europe.

CPSC 1203 is the standard bicycle helmet certification for bicycle helmets including open-face mountain bike helmets.

Many, but not all, full-face mountain bike helmets are certified for downhill racing and carry ASTM F1952 certification. Downhill certification is recommended for full-face helmets with a chin-bar, which is the choice of serious downhill enduro racing enthusiasts.

MIPS – Multi-directional Impact Protection System

The third thing that you can do to enhance your head’s safety is to choose a mountain bike helmet with MIPS.

MIPS (Multi-directional Impact Protection System) is an added layer of protection in many types of helmets including MIPS Mountain Bike Helmets.

The benefit of the MIPS brain protection system is that it can reduce rotational forces during an impact. These rotational forces can otherwise cause serious injury to your brain. The MIPS layer inside your helmet helps to reduce the rotational motion and in doing so reduces the sudden pressure on your brain during impact.

Helmet Condition

You, the rider, need to ensure that your helmet is in top-notch condition. You should regularly check that the outer shell of your helmet has no chips or cracks; check that the chin-strap is not twisted or fraying, and that it is securely attached to your helmet. If in doubt, toss it out!
