Overview

Engineered for all forms of off-road riding, this advanced chest and back protector system offers a perfect balance between high-level impact protection and superior ventilation. Anatomically profiled for an optimized performance fit, the protector features a semi-rigid thermoplastic polyhedron chest design combined with a flexible back protector for maximum safety without compromising mobility.

Advanced Impact Protection
The protector utilizes a highly flexible Nucleon Plasma back protector, constructed from viscoelastic, bio-based polymers. This structure is pliable in all directions to follow the body's natural movements while effectively dissipating impact energies. The triple-layer chest protector includes a highly perforated impact absorption insert, complemented by thermoformed perforated rib protection panels and an additional EVA tail extension for extended coverage to the lower spine.

Superior Breathability and Comfort
Designed to keep riders cool in the most demanding conditions, the protector features perforated plastic shells and a perforated 3D mesh chassis. The internal lining is ribbed for superior airflow, reducing the material contact with the skin for a soft tactile feel. A thermoformed padded chassis ensures a close-to-body fit, while the lightweight, ultra-vented design provides strong impact force dispersion and maximum coverage in all riding positions.

Customizable and Secure Fit
Achieve a personalized fit with adjustable elastic shoulder and side straps. The system features over-injected flexible side wings that follow the body's contours, along with removable and adjustable shoulder padding for high levels of customization. An elastic closure system incorporates newly designed, quick and easy-to-use buckles that accommodate a broad range of body sizes.

Technical Integration and Sustainability
This protector is fully compatible with Bionic Neck Support (BNS) systems via integrated silicon pull tabs for easy and safe engagement. It is also engineered to be compatible with extended roost coverage kits for those requiring additional protection. Notably, the impact-absorbing material is USDA-certified bio-based, offering an eco-friendly and sustainable solution for off-road safety.
