Pure performance. Zero compromise.
An ultra-light, maximally perforated racing suit built for riders who demand the highest level of safety and performance. Worn by professional racers and now available to you. On the bike, everything is about freedom, movement, and feel. The Racing Ultra Light Matrix AR® delivers all three, without compromise—and it’s fully Airbag Ready®.
Designed for the world of motorsport where milliseconds matter and style is part of a rider’s identity, the Matrix AR® is crafted from premium 0.9 mm kangaroo leather and engineered to push your limits. Extensive seamless aramid stretch panels provide exceptional freedom of movement, allowing the suit to move with you in every riding position.
The Airbag Ready® system gives you flexibility: ride with a full set of 18 ergonomic protectors, including chest and back protection, or remove the chest and back protector and wear an approved airbag system underneath. Fast, simple, and race-ready.
