Equipped with the industry-leading MIPS liner and an EPS foam shell, the Mainframe offers maximum impact protection, ensuring you can ride knowing you're protected for any eventuality!

The Mainframe has been equipped with a removable moisture-wicking inner lining and Fox's unique 360° fit system to ensure you have a secure and comfortable ride every time!
