The Alpinestars Bionic Pro Knee/Shin Guards offer lightweight hybrid knee/shin protection with high comfort and maximum breathability. The shell is constructed from a high-performance polymeric material blend for optimized flexibility and excellent weigh-saving properties. The shell is also highly perforated for maximum breathability and air ventilation, which helps keep your knees feeling fresh all day long. The new single injected compound shells constructed with a back integrated grid structure absorb and dissipate impact forces, keeping your knees safe from hard impacts.
Soft and impact absorbing padding on the side outer part for additional comfort.
New technical elastane main construction is highly breathable and retains shape.
Soft perforated PE foam gives more comfort and breathability.
Additional lower protective zone for extended lower leg coverage.
Internal rounded thermoformed padding with an additional viscoelastic foam for a perfect fit and better protection of the rotula.
Triple strap closure system specially designed offers more comfort and adjustment with top strap mounted above the knee and middle and lower positioned for ergonomic fit.
