A-Impact Plasma Pro Knee Shin Protectors

Integrated Nucleon PLASMA Knee Shin Protector
The integrated Nucleon PLASMA Knee Shin Protector uses Alpinestars' Nucleon PLASMA Technology for effective impact protection. Its Nucleon PLASMA element is constructed from a bio-based viscoelastic impact-absorbing compound with no less than 25% bio-based content, which dissipates impact energy and significantly reduces transmitted forces through controlled material response.

Low-profile PLASMA geometry
The PLASMA element is molded into a precision-engineered, low-profile geometry developed to compress and extend with movement, while its channeled and highly-perforated design supports airflow.

Abrasion-resistant textile front panel
The front panel is constructed from highly abrasion-resistant textile for durability.

Laminated ripstop PE foam and poly-mesh
The protectors are constructed from laminated ripstop PE foam and poly-mesh for superior breathability and airflow.

Breathable rear mesh panels
The rear knee and shin panels are constructed from breathable mesh, with a wide opening behind the knees and shins for airflow.

Pre-curved ergonomic design
The highly flexible, lightweight knee and shin protectors feature a pre-curved, ergonomic design for optimized performance in various riding positions.

Strategic lateral padding
Extra lateral padding is positioned in strategic areas of the inner and outer knees and shins to provide additional coverage.

Strap retention closure system
The secure closure system incorporates loops that hold the straps in place behind the knees and shins to ensure the protectors remain fully secured.

Silicone-printed inner liner
Silicone printing on the inner liner prevents the protectors from being displaced while riding.

Stretch mesh compression panel
A stretch mesh panel improves stability and provides a firm compression fit and soft tissue support for all styles of riding.
