Alpinestars A-4 Plasma Chest Protector Black Red White

The Alpinestars A-4 Plasma Chest Protector is anatomically designed for off-road riding. It features a semi-rigid thermoplastic polyhedron design chest protector and a Nucleon Plasma back protector, both engineered to be lightweight, breathable, comfortable, adaptive, and protective. Crafted from a USDA Certified Biobased viscoelastic material, it is lightweight and ultra-durable. The protector moulds to the body for a close fit, effectively dissipating impact energy to deliver reliable protection. It is highly ventilated for superior airflow and comfort. The over-injected flexible side wings of the chest protector perfectly follow the body's contours for exceptional comfort and freedom of movement. It is compatible with the Nucleon Plasma Extended Roost Coverage kit, which includes Upper and Lower Chest Extensions and an additional Y-Strap System, allowing riders to use the A-4 Chest Protector without the back protector. The A-4 Plasma Chest Protector features highly perforated, adjustable, and detachable rib and shoulder padding for additional coverage against roost and impact. It is BNS compatible via the elasticated BNS pull tabs situated on the removable soft tactile thermoformed shoulder pads. It is constructed from Certified Biobased, eco-friendly, and sustainable impact-absorbing material and comes equipped with adjustable shoulder and side straps for an optimised performance fit. Removable soft tactile thermoformed shoulder padding gives enhanced rider comfort. The lining on the back protector provides a smooth tactile feeling against the skin while maintaining the protector's integral structure and reducing the risk of 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. The back protector is CE EN 1621-2:2014 LEVEL 1, and the chest protector is CE EN 1621-3:2018 LEVEL 1.
