Alpinestars Nucleon Flex Pro Knee Guards

Experience the pinnacle of rider protection and comfort with the Alpinestars Nucleon Flex Pro Knee Guards. Designed for the discerning motorcyclist who refuses to compromise on safety or mobility, these guards set a new standard in body protection. Incorporating innovative Nucleon Flex Pro technology that is lightweight and ventilated, the Nucleon Flex family of protectors is ergonomically engineered for comfort, convenience, performance and protection. The result is a high-performance knee guard that feels like a natural extension of your body, providing CE-certified Level 2 impact absorption without the bulk and restriction of traditional armor.

The unique design of the Nucleon Flex Pro is centered around a highly ventilated, open-structure grid that not only dissipates impact forces effectively but also allows for exceptional airflow, keeping you cool and comfortable on long rides or in warm conditions. Its ergonomic, pre-curved shape is specifically contoured to the riding position, ensuring a perfect, non-intrusive fit that moves with you, preventing uncomfortable bunching and allowing for complete freedom of movement whether you´re carving through canyons or navigating city streets.

Key Benefits:

* Superior Impact Safety: Achieves the highest CE Level 2 certification (EN 1621-1:2012), offering exceptional protection against impacts by effectively absorbing and dispersing energy. Ride with the confidence that your knees are shielded by cutting-edge safety technology.
* Unparalleled Comfort & Flexibility: The bio-mechanical Flex Pro technology allows the protector to conform precisely to your knee´s shape and movement. The lightweight construction and soft-touch comfort liner mean you´ll barely notice you´re wearing them.
* Advanced Climate Control: Say goodbye to sweaty, uncomfortable armor. The extensive perforation and open-back design provide maximum ventilation, promoting airflow to reduce heat and moisture build-up, ensuring comfort on even the most demanding rides.
* Secure & Stable Fit: Featuring a convenient slip-on design with elasticated upper and lower straps, these guards are incredibly easy to put on and take off. Silicone printing on the inner cuffs prevents the guards from slipping or migrating, ensuring they stay exactly where you need them, lap after lap.

Main Features:

* Exclusive Nucleon Flex Pro protective technology for an optimal balance of flexibility and impact absorption.
* Ergonomically engineered and pre-curved for performance and comfort in the active riding position.
* Convenient slip-on design for quick and easy use.
* Open-back construction for enhanced ventilation and reduced material behind the knee.
* Dual elasticated strap closure system for a secure and personalized fit.
* Silicone printing on the interior cuffs to prevent slippage and ensure the protector remains in place.
