Alpinestars A-4 Plasma Chest Protector - Black Red White

Designed for all off-road riding, the A-4 Plasma Chest Protector features a semi-rigid thermoplastic polyhedron design chest protector and a Plasma back protector that are engineered to be lightweight, breathable, comfortable, adaptive and protectiveKey FeaturesHighly flexible Nucleon Plasma Back Protector: Constructed from viscoelastic material engineered from bio-based polymers and formed into a structure that is pliable in all directions while maintaining the ability to dissipate impact energies. Lightweight and highly ventilated, this protector offers strong impact force dispersion and absorption while ensuring maximum coverage area in all riding positions. Lightweight and ultra-vented chest armour: The chest outer shell ™s design is based on geodesic polyhedrons, and like a geodesic dome, less material is needed to achieve the desired structural strength and imposed load performance when compared to flat or unfaceted surfaces.

The over-injected flexible side wings of the chest protector perfectly follow the body ™s contours for superior comfort and freedom of movement. Optional Race kit: Engineered to be compatible with the Nucleon Plasma Extended Roost Coverage kit which includes Upper and Lower Chest Extensions, and an additional Y-Strap System to use the A-4 Chest without the back protector. Rib and shoulder coverage: A-4 Plasma Chest Protector features highly perforated, adjustable and detachable rib and shoulder padding for additional coverage against roost and impact. Construction Equipped with adjustable shoulder and side straps for an optimised performance fit. Removable soft tactile thermoformed shoulder padding for enhanced rider comfort. The lining on the back protector offers a soft tactile feeling against the skin while maintaining the integral structure of the protectors and reducing the risk of any material tearing. The lining is ribbed for superior airflow while also reducing the amount of material that is in contact with the skin. The perforated 3D mesh chassis also offers additional protection against tire roost. Bionic Neck Support compatibility via the BNS shoulder pull tabs.
