Our opinion:

This suit features technologies tested by Moto GP riders such as Marc Marquez.
It is made of kangaroo and bovine leather to combine flexibility and durability.
In terms of safety, it incorporates multiple next-generation protections at the elbows, knees, shoulders... all CE certified and is pre-equipped to receive a back and chest protector to enhance the level of protection.
The external anatomical GP DFS sliders are a blend of triple-density polymer ensuring enhanced performance in case of a slide and are equipped with removable and replaceable screw inserts.
This suit has been redesigned to offer even more comfort in the riding position with its Matryx® fabric inserts as well as thermal comfort with the Ircooltech treatment, which is an integrated treatment in the leather.
This innovative technology reflects infrared rays from the sun, preventing heat accumulation and thus regulating the temperature inside the suit.
