ALPINESTARS A-4 PLASMA CHEST PROTECTOR

Anatomically profiled for all forms of off-road riding and downhill MTB, the A-4 PLASMA Chest Protector combines a semi-rigid thermoplastic polyhedron chest panel with a Nucleon PLASMA back protector. Lightweight, breathable, and adaptive, it delivers outstanding comfort and protection without compromising mobility.

Features:

– Highly 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 armor: 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.

– This results in a protector where the whole is greater than the sum of all its parts, making the new A-4 PLASMA Chest Protector supremely light-weight and ventilated. 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.

– USDA certified bio-based eco-friendly and sustainable impact absorbing material.
