The Details

Offering the same level of quality, protection and style as the adult version of the Mainframe. This fashionable and well-priced trail helmet has many excellent safety features including the MIPS impact protection technology and extended head coverage for maximum safety when hitting the trails. Excellent protection at an excellent price.

The MIPS impact protection system helps to redistribute the damaging rotational energy created during a crash. This, in turn, helps to lessen the effects of the impact on your head and neck. 

The Mainframe also has a lightweight fit system and is well ventilated to prevent overheating when pushing the limit on the trail. Its design consists of a lightweight fit system and an optimised vent system to aid airflow. The Mainframe also includes a moisture-wicking liner that can easily be removed and washed if sweat does build up. 

  • MIPS protection system
  • Extended head coverage
  • Washable inner liner

Our Verdict

The Youth Mainframe helmet is just as good as the adult Mainframe so you know this helmet is both extremely safe as well as stylish.
