The Fox Mainframe Helmet w/ MIPS is a mountain bike helmet for the budget-conscious rider. Don't break the bank, and don't break your head. Crashes can happen when riding hard and having fun, but with MIPS technology, rotational motion is reduced for increased head protection. The multiple vents offer airflow, plus the moisture-wicking liner is removable for washing to keep it fresh for the next ride.
