DescriptionThe whole story▼
The Dainese Pro-Armor Back Short 2.0 is a Level 2-certified back protector engineered specifically for riders of height below 174 cm/68.5 in who refuse to compromise between protection and freedom of movement. Built around Dainese's Xelion 2.0 compound — an expanded nitrile rubber construction with thermoplastic bearings — it achieves a rare combination of featherlight flexibility and certified impact absorption that holds up mile after mile.
Key Features
- CE Category II certified to EN 1621.2/2014 Level 2 — the highest back-protection rating available for motorcycle armour
- Xelion 2.0 construction: expanded nitrile rubber with thermoplastic bearings delivers maximum flexibility alongside superior shock absorption
- Fractal design architecture with 4 bearings and 5 degrees of movement, accommodating lateral flexion, longitudinal extension and rotational motion simultaneously
- Perforated structure throughout promotes continuous airflow, keeping the back cool and dry on long touring days and hot-weather track sessions alike
- Dynamic variable thickness adapts the profile to individual body contours for a precise, personalised fit
- Removable and adjustable lumbar strap plus detachable straps allow the protector to be configured for different riding positions and body types
Construction and Materials
Where many back protectors rely on dense foam that stiffens over time, the Pro-Armor Back Short 2.0 uses Dainese's proprietary Xelion 2.0 material — an expanded nitrile rubber compound paired with thermoplastic bearing nodes. The result is a protector that remains genuinely soft and pliable against the spine throughout a full riding day, never creating the pressure points that plague stiffer alternatives. The thermoplastic bearings pivot at four articulation points, granting five independent degrees of freedom so the panel follows spinal movement rather than resisting it.
The perforated surface is not a cosmetic detail — it is structural. Open channels run across the entire contact face, encouraging convective airflow between the protector and the jacket lining. On a long touring run or a sustained track day, this ventilation makes a measurable difference to comfort and concentration.
Ergonomics and Fit
The short format is sized for riders standing below 174 cm/68.5 in, meaning the protector sits correctly across the lumbar and thoracic zones without overrunning the waist or creating bunching at the seat. The removable lumbar strap locks the panel into position under braking and cornering loads, while the detachable adjustment straps let each rider dial in lateral tension to suit their jacket cut. Two waist sizes are available: M fits waists up to 89 cm/35 in and L fits waists above 90 cm/35.4 in.
Intended Use
Designed to serve equally well on long touring routes, spirited road riding and trackday sessions, the Pro-Armor Back Short 2.0 is the back protector for riders who spend serious hours in the saddle and need armour that genuinely disappears into the background. The Level 2 certification confirms it meets rigorous impact-attenuation standards, so the comfort credentials are never bought at the expense of safety performance.
Fitment and Compatibility
The Pro-Armor Back Short 2.0 is a standalone back protector designed to insert into compatible Dainese jackets that feature a back-protector pocket, or to be worn directly against the body. Verify your jacket's back-protector pocket dimensions against the product sizing before purchase. Height requirement: below 174 cm/68.5 in.
Warranty
Covered by a 2-year manufacturer warranty against conformity defects, entitling the owner to free repair or replacement of parts under Dainese's standard conditions. Registering the product within 30 days of purchase extends coverage to 3 years.
