ALPINESTARS Bionic Action Protector Shorts

Key Features and Protection

• Certification: The shorts and their hip protectors are CE and UKCA certified Level 1.
• Protection: They feature built-in, strategically positioned padding and impact-absorbing foam in key areas that are prone to injury, which often include the hips, lower back, seat, and outer thigh areas.
• Hip Protection Design: The hip protection often uses a two-part, split-joint overlapping construction where the protector meets the stretch mesh chassis. This design allows for complete protection without restricting the rider’s freedom of movement.

Comfort and Construction

• Chassis/Material: The shorts are constructed with a soft-touch, stretchy fabric chassis and a breathable mesh sleeve.
• Flexibility: They are designed to be lightweight and highly flexible to ensure maximum comfort and excellent freedom of movement.
• Airflow: The breathable mesh material provides excellent airflow and ventilation, enhancing comfort during use.
• Chamois Padding: They typically include a comfortable, MX or enduro-orientated chamois padding (a cushioned pad similar to what is found in cycling shorts).
• Additional Features:
  • Elasticated straps/waist strap.
  • Stretchable lower thigh hem for compatibility with knee braces/protectors.
  • Some versions incorporate Polygiene Biostatic™ freshness retention technology to help maintain hygiene and freshness.

Intended Use

The design, including the focus on impact points determined by crash studies, makes them ideal for various motorsports, particularly:

• Motocross (MX) and Enduro/Dirt Riding
• Track Competition (motorcycling)
• Karting (where they help reduce injuries from the kart seat).

The shorts are intended to be worn as a base layer underneath an outer suit or pants.
