For a long time, manufacturers produced standard mountain bike helmets without considering head shapes. People with oval-shaped heads found it almost impossible to find a helmet that fit right. Most helmets would fit in the front and stay loose at the back or vice versa, hence causing a lot of discomfort. Luckily, manufacturers have identified this gap and are now making mountain bike helmets targeted at those with oval heads. In this post, we have rounded up some of the best mountain bike helmets in this category so that you can decide on the right helmet for yourself or your loved ones!

We were particularly pleased with this helmet’s ability to enhance airflow. It uses an advanced technology, known as the Ventuli Effect to channel cool air in from the top and push the hot air out through the rear exhaust system.
