Anatomically profiled for all forms of off-road riding including Motocross and Supercross, the A-5 Plasma Chest Protector features composite Nucleon Plasma and semirigid thermoplastic chest and back protector shells that are engineered to be lightweight, breathable, comfortable, adaptive and protective. The Level 2 CE certified chest and back protectors are mounted on a highly perforated 3-D mesh for superior airflow and breathability. The side wings are independent from the main semi-rigid chest protector outer shell to ensure a fully adaptive fit. The Level 2 CE certified back protector is a composite construction and has a central semi-rigid thermoplastic zone on a Nucleon Plasma back protector for greater impact force dispersion in a critical area. Protectors have an adaptive for that perfectly follow the body’s contours for superior comfort and freedom of movement. Nucleon Plasma is a 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 knee protector offers strong impact force dispersion and absorption while ensuring maximum coverage area in all riding positions.
Features:
USDA certified bio-based eco-friendly and sustainable impact-absorbing material.
Equipped with adjustable shoulder and side straps for an optimized performance fit.
Removable soft tactile thermoformed shoulder padding for enhanced rider comfort.
Liners on the chest and back protectors maintain the integral structure of the protectors and reduce the risk of any material tearing.
The liners are 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.
Great service and easy to order from!
Guard is Super comfortable to wear

great saving
I was hesitant about purchasing but took the chance. I'm so glad I did. The helmet came as described and fast too. I used the savings for another visor (blue). Not only was shipping free, but I also saved on taxes.

Excellent boots
Love my new boots. I actually forgot I was wearing new boots when I rode with them the first time because they just felt good and familiar. I’ve always used Alpinestars, but this change is definitely worth it. Also $100 less than alpinstar 7’s. My only complaint would be these definitely need insoles to make the soles more plush. Kind of hard with factory insoles.

Great helmet and great experience.
I decided to try Moto Psycho Sport and picked up an open box Shoei RF 1400 helmet for quit a bit less than full retail. Couldn’t be happier with the helmet and the quick shipping. The helmet was perfect, no damage and all the original parts in the box. I won’t hesitate to buy from them again.
