The corax jacket pro have been studied to defend from collisions to the spinal  column, the top-limbs and to give a good kidney support to the adult/ junior. These items are provided with back and top-limbs guards that offer a great advantage: the user can perfectly regulate them according to its own sizes, thanks to a Velcro-elastics regulation system. The chest guards have been realized with an innovative material, the Elastollan 660 DU, very resistant from bumps, twisting and abrasion. The back guard is composed by highly technological materials: Polyurethane Plates highly qualified and tested, which offer the advantage, when compared to normal materials used up to now (Polypropylenes or thermoformed materials, etc.), of not producing splinters in cases of blows or accidents (the same material is used, for example, in ski boots); The structure underneath the plates has a Memory System of Cells which guarantees top shock-absorption level. The plates are joined to a drop wire system which guarantees the impact distribution throughout the whole surface of the guard.
