Key features of RST Race Dept D3O Strapped Back Protector
Sportsbikeshop lists the following details for the checked version:
- 3D mesh main construction
- Memory foam coccyx protection
- Double waist closure for a more secure and personalised fit
- CE certified level 2
Protection and construction
The protector is listed as CE Level 2. This is a rating for the protector, not a new certification for the rest of the riding kit.
Compatibility and positioning
Compare the protector’s size and outline with the intended garment or fitting system. A matching brand name alone does not establish compatibility. Check the position when wearing the complete riding kit and moving into your riding posture. The protector’s own rating should not be confused with certification of an entire garment.
