The Fox D3O Viper Back Insert is the back protector that slots into compatible Fox garments, giving full back coverage on trails, enduro runs and bike park days. Light and low-profile, it uses D3O material to stay flexible while you ride and absorb energy on impact.
The Airwave design creates channels that let air move between your back and the insert, so heat builds up less even on long climbs. Its ergonomic shape follows the curve of your back and leaves you free to move on the bike. CE certification to EN 1621-2:2014 Level 1 confirms its protection level.
D3O back protection and comfort
- Patented D3O material: flexible in motion, absorbs impact energy
- Airwave structure for better airflow

Why choose the Fox D3O Viper insert
