Expert Reviews

  • Despite having additional vents, the ventilation isn’t the best compared to other options.
  • Not the best combination of lightweight and airiness when compared to other options on the market.
  • The glasses storage is not fully compatible with every single option.
  • The exterior makes this helmet heavier than other similar options on the market due to the beefy material.


The Bell Sixer MIPS Helmet is a protective, adjustable, and comfortable option that can work well for many different levels of mountain bikers. Even though this helmet is a bit heavier and not as ventilated as some other options on the market, if you are looking for a helmet that will protect you with a MIPS liner in any crash, can be easily adjusted on the fly, and features a camera mount for tech compatibility, this could be a good choice for you.
