Zandona Shield back protector (CE approved) have been studied to protect the spinal column from collisions and to give a good kidney support. These protections are 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 protection surface. The coupled material of P.E. + tissue, which is support of the protective system, is Soft, Transpiring and Anti-bacterial. The plates number have to be chosen according to the lumbar zone to protect or to the user height; the excellent and comfortable waist closing have gotten by the double elastic regulation system of the lumbar belt.
