A rigid external plastic shell absorbs and distributes impact energy over the protectors entire surface thanks to a patented reticulate structure that also offers lower thickness and weight. The inside of the protector in high-density polyethylene foam has elevated deformability and high shape memory retention that ensures greater comfort through adaptation to the wearers body, which is also served by perforation on the outside that increases breathability. capable of combining a high level of protection for compliance to the Standard with extreme flexibility and incomparable comfort. A sandwich composed of an outer layer in polymer derived from F1 racing with the highest shock absorption capacity and remarkable elasticity is bonded to an inner layer of polyethylene foam of the highest thickness to create an extremely flexible and deformable structure that also vaunts high shape retention for adaptation to the shapes of the body in order to ensure excellent ergonomics able to follow the body in even its smallest movements The perforated structure also ensures the correct ventilation of the area for greater riding comfort. 2.0 : soft protectors certified to EN 1621.1 Standard on hips EN 17092 AA certified motorbike garment Interchangeable Ergonomics and Other Features: Elasticated inserts Hips adjustment Jacket-pants fastening system 2 Zips calf construction with Boots-in system Knee Slider RSS 4.0 Reflective inserts
