Back protectors are the single most important spine defence a rider can add. This range carries CE Level 1 and CE Level 2 certified armour from Leatt, Merlin, Macna, Armanox and Shot, including slim D3O inserts and ventilated central panels sized to fit hydration bags, jackets and standalone harnesses.

How to Choose a Back Protector
CE certification is the only standard that matters for spine armour. Every protector here meets EN 1621-2, the European back impact standard, in either Level 1 or Level 2. Level 2 transmits a maximum average of 9 kN of force in testing, while Level 1 permits up to 18 kN, so Level 2 halves the force reaching your spine.
| Spec | CE Level 1 | CE Level 2 |
|---|---|---|
| Standard | EN 1621-2 | EN 1621-2 |
| Max force transmitted | 18 kN | 9 kN |
| Typical use | Road, commuting | Track, adventure, MX |
| Profile | Slimmer, flexible | Fuller coverage |
Fit decides effectiveness. The Macna R.I.S.C. central protector covers a 43 to 48 cm span in Large and 38 to 43 cm in Medium, so measure from the base of your neck to your waistline before buying. The Merlin D3O Viper Stealth measures 440 mm long by 270 mm wide and uses D3O, a soft material that stiffens on impact and stays flexible at rest.
Match the protector to your kit. Slim inserts like the Merlin Viper Stealth slot into jacket back pockets at a 25 mm profile. The Leatt protector is built to sit inside a hydration bag, and the Shot Air Guard SRG-1 runs a perforated shell for airflow in heat. For full torso cover, pair spine armour with a separate chest protector rather than relying on foam back inserts.
Frequently asked questions
What is the difference between CE Level 1 and Level 2 back protectors?
Both meet the EN 1621-2 standard. CE Level 1 transmits up to 18 kN of impact force, while CE Level 2 transmits a maximum of 9 kN. Level 2 offers higher protection and suits track, adventure and off-road riding, while Level 1 is slimmer for everyday road use.
How do I size a back protector correctly?
Measure from the base of your neck down to your waistline along your spine. Match that length to the protector. The Macna R.I.S.C. central protector, for example, covers 38 to 43 cm in Medium and 43 to 48 cm in Large, so the armour should span your full spine without riding up.
Can a back protector fit inside my jacket or hydration pack?
Yes. Slim D3O inserts like the Merlin Viper Stealth slot into jacket back pockets, and the Leatt back protector is designed to fit inside a hydration bag. Standalone harnesses such as the Shot Air Guard SRG-1 wear over your base layer.
