Alpinestars Bionic Action Chest Protector M/L — Lightweight CE‑Certified Off‑Road Ventilated Black/Red

The Alpinestars Bionic Action Chest Protector is a featherweight, CE‑certified off‑road upper‑body protector that balances impact coverage with ventilation and mobility.

Designed for trail, enduro and motocross riders who want dependable impact resistance without bulk, this protector pairs a ventilated front shell and a softer, adaptive rear plate with bio‑foam backing for a comfortable close fit. The system uses Alpinestars' new Cell Technology in the chest plate to maximize airflow and reduce weight, while removable shoulder pads and flexible sides let the unit conform to different body shapes and riding positions.

How does the Bionic Action keep you cool during long rides?

The chest and back shells are highly perforated to promote continuous air exchange, and the thermoformed padded chassis sits snugly without trapping heat. Together these elements reduce sweat buildup and help riders stay comfortable during extended sessions.

• Cell Technology front shell with extensive perforations for airflow
• Perforated back protector and shoulder pads to aid ventilation
• Thermoformed padding designed to fit close to the body without restricting breathability

Will it restrict arm movement or riding posture?

No — the protector was designed to maintain a full range of motion. The flexible side panels and lower-profile shell allow arms to move freely for braking, shifting and steering while still protecting the chest and ribs.

• Flexible side section adapts to rider motion and anatomy
• Low-profile shell contours to the torso so shoulders and arms remain unrestricted
• Removable shoulder pads allow customization to suit different riding styles

What kind of impact protection does it provide?

Front and rear hard plates are supported by a layer of bio‑foam that cushions impacts and keeps the shells positioned correctly on the body. The unit is CE‑certified, indicating it meets accepted standards for protective performance on the trails.

• Hard shell plates on chest and back for direct impact resistance
• Bio‑foam backing provides energy absorption and a secure fit
• CE certification ensures the protector conforms to recognized safety benchmarks

How easy is it to get on, adjust, and personalize?

The protector slips on quickly and is engineered for straightforward adjustments so riders can tune fit and coverage in minutes. Shoulder pads are removable for riders who prefer less bulk or who need to pair the unit with different outer layers.

• Quick to put on and remove for rapid transitions between rides
• Adjustable fit components let you dial in comfort and stability
• Removable shoulder pads and adaptable sides for personalized setup

Who is this for: The Alpinestars Bionic Action Chest Protector is ideal for off‑road riders — from weekend trail riders to competitive enduro and motocross racers — who want certified impact protection without sacrificing ventilation and freedom of movement. It suits riders who prefer a close, adaptive fit and who may want to tailor shoulder coverage based on terrain or layered gear.
