Acerbis Spine Protector Blazar

Soft Level 2 back protector

The Acerbis Blazar is a lightweight and flexible back protector designed for motorsports, cycling, horse riding, winter sports and other activities where protection of the spinal area is required. Its soft viscoelastic insert adapts to the shape of the rider’s back, maintains freedom of movement and helps reduce impact energy transmitted to the protected area.

Large ventilation openings pass through the protective insert, supporting airflow, reducing unnecessary weight and allowing the construction to follow body movement. Highly breathable 3D mesh on the inner surface separates the protective material from the rider’s back and helps manage heat and moisture.

The protector complies with EN 1621-2:2014, Level 2. Adjustable shoulder straps and a perforated waist belt allow its position and circumference to be adapted to different body proportions.

Certified Level 2 back protection

The main protective component uses soft viscoelastic foam covering the spinal area and the adjacent parts of the back. During normal use, the material follows the body’s curvature and creates less resistance during forward lean and torso rotation than a large rigid plastic shell.

During an impact, the multi-layer foam structure helps absorb and distribute part of the applied energy. Its purpose is to reduce the force transmitted to the back, although no protector can prevent every type of injury or replace appropriate riding technique and other safety equipment.

The Acerbis Blazar is certified to EN 1621-2:2014, Level 2. This is the higher of the two protection levels defined by the standard for motorcycle back protectors.

Certification confirms that the protector has passed the prescribed laboratory impact-transmission tests. Correct performance still depends on selecting the right size, covering the intended area and keeping the protector securely positioned during movement.

Body-adaptive viscoelastic foam

The soft protective insert responds to the shape of the rider’s back and gradually adapts to individual body proportions. A closer fit helps distribute pressure more evenly and reduces concentrated hard contact points.

The viscoelastic material remains flexible during ordinary movement. The wearer can therefore lean forward, rotate the torso and change position without the significant resistance of rigid articulated components.

During an impact, the material helps reduce the energy transferred to the protected area. It can return to its original shape after temporary loading, provided that it has not suffered mechanical or structural damage.

The use of memory-type foam does not mean that the protector can automatically continue to be used after every fall. Following a major impact, the complete protective component should be inspected and must not be used if it is cracked, torn or permanently deformed.

Large ventilation openings

Large openings are distributed throughout the protector. They allow air to move towards the rider’s back and help release heat from the space between the body and protective insert.

The open structure also reduces the amount of material used and therefore the overall weight. Dividing the surface with ventilation openings supports flexibility during forward lean and other torso movements.

Ventilation cannot prevent perspiration, particularly during intensive physical activity or high temperatures. It does, however, help limit heat accumulation and encourages continuous air exchange around the back.

Breathable 3D mesh

The surface in contact with the rider’s back is covered with three-dimensional mesh. Its structure creates air channels between the skin or base layer and the protective foam.

The mesh helps move moisture away and prevents the complete back surface from resting directly against smooth protective material. This supports comfort during longer rides, physically demanding activities and warmer conditions.

The material also improves contact comfort and helps distribute pressure from the protector more evenly across the back.

Perforated external fabric

Flexible perforated fabric covers the outside of the protective insert. It helps protect the soft viscoelastic material from regular mechanical wear while maintaining its flexibility.

The perforations complement the openings in the protector and avoid sealing the foam inside a completely closed cover. Stretch material moves together with the insert during forward lean and torso rotation.

The textile cover also reduces direct contact between the foam and other equipment and protects its surface during regular use, transport and storage.

Adjustable shoulder straps

Elastic shoulder straps allow the protector’s vertical position to be adjusted. Correct adjustment places the upper section below the neck while keeping the lower part correctly positioned above the waist.

The straps should be adjusted evenly so that the protector does not lean towards one side. They must not cut into the shoulders or restrict natural arm movement.

The shoulder straps are not intended to support the protector alone. Stability is supplemented by the waist belt, which holds the lower section close to the body.

Perforated waist belt

A wide perforated belt wraps around the waist and helps keep the protector close to the back. Elastic side sections adapt to torso movement and changes in circumference during breathing.

Perforations encourage airflow around the waist, where heat can accumulate underneath protective equipment. The wide construction also distributes pressure over a larger area than narrow fastening straps.

Hook-and-loop fastening provides continuous adjustment according to the rider’s body and clothing layers. The belt should be secure enough to prevent movement without restricting breathing or creating uncomfortable pressure.

Before every use, check the condition of the fastening and remove dirt that could reduce its grip.

Unisex anatomical construction

The design is intended to adapt to both female and male anatomy. The important selection criteria are not gender labels but protector length, position over the back and stability during movement.

A soft insert, adjustable shoulder straps and a stretch waist belt allow the fit to accommodate different body proportions.

A correctly selected protector should cover the spinal area, remain below the neck during forward lean and avoid significant sideways movement.

Freedom of movement

The Blazar does not contain rigid joints or a large plastic shell. Its soft protective material can therefore bend together with the back and adapt to different sporting positions.

This flexibility is useful when riding a motorcycle seated or standing, pedalling a bicycle, leaning forward on horseback or moving during winter sports.

The low-profile design can be worn underneath an appropriate jacket, jersey or other outer layer. The outer garment must not be so tight that it deforms the protector or pushes it away from the correct position.

Motorsport use

During motocross, enduro, road motorcycle use or ATV riding, the protector covers the spinal area without the extensive construction of complete body armour.

The Blazar protects only the back. It does not include chest, shoulder, elbow or hip protection. Separate equipment must be added where broader coverage is required.

It is also not a substitute for a motorcycle jacket or other abrasion-resistant clothing. For road use, suitable outer equipment providing protection during a slide on asphalt remains necessary.

Cycling use

Its soft construction and large ventilation openings make the Blazar suitable for mountain biking, enduro cycling, downhill riding and bike-park use. It can follow the forward-leaning cycling position while leaving the arms and chest unrestricted.

For cycling, the protector should be tried on together with the jersey, backpack or waist pack. Straps from other equipment must not create pressure that moves or deforms the protector.

Horse riding and winter sports

The unisex design is also suitable for horse riding and selected winter sports where flexible back protection is required.

Compatibility with other equipment and the regulations of the particular activity must always be checked. EN 1621-2 is a motorcycle standard and may not replace a specific certification required by a sporting federation, competition or facility operator.

Selecting the correct size

The Acerbis Blazar is available in:

• S/M,

• L/XL,

• XXL.

Body height, torso length and waist circumference should all be considered. The clothing-size designation is only an initial guide.

The upper section should not extend excessively towards the neck, while the lower section should cover the appropriate back area without restricting movement at the waist. The belt must close securely with sufficient adjustment remaining.

Before use, perform forward lean, torso rotation and movements typical of the intended activity. The protector should remain stable without restricting breathing, creating pressure or interfering with the helmet or other equipment.

Inspection after a fall

Following a strong impact or fall, the complete protector should be inspected. Particular attention should be paid to the foam insert, outer fabric, shoulder straps and waist-belt connections.

A protector with cracks, torn foam, damaged seams, faulty fastening or permanent deformation must not continue to be used.

Even where no damage is visible, a severe or repeated impact may affect the material’s protective properties. Where there is doubt, replacing the protector is the safer option.

Care

Cleaning must follow the instructions on the product label. Aggressive detergents, solvents and high temperatures can damage the foam, elastic components or textile cover.

After use, the protector should be allowed to dry naturally in a well-ventilated place. It should not be dried on a radiator, near an open flame or under prolonged direct sunlight.

The protector must be completely dry before storage. It should not remain folded, compressed beneath heavy objects or sealed inside a damp equipment bag.
