Premium back protector that easily moulds to the shape of your back, but hardens on impact. Can fit in most Kevlar hoodies and leather jackets as an insert, or use in our Ashvault Backpack back protector compartment.
Size: 412mm x 242mm x 20mm
Suits Dainese leather and textile motorcycle jackets, Alpinestars leather and textile motorcycle jackets, most Kevlar hoodies and jackets - please email us to confirm if unsure.
Viscoelastic armour is able to achieve a higher level of shock/impact reducing benefits with more comfort and less bulk than traditional hard armour - foam laminate solutions. Hybrid armour is layered with hard shell outer materials.
European standard EN-1621 is used to rate the effectiveness of armour. In this standard, a 5 kg flat impactor impacts the armour at a speed of 4.47 m/s (energy 5x4,47x4,47/2=50 J "Joules"). 50 J of energy is roughly equivalent to dropping a 1 kg mass from a height of 5m (E=mGH). Sensors measure how much force is transmitted through the armour, its peak force in kilo-newtons (kN), and its period (how long it took the force to be transmitted). If the force transmitted through the armour is less than 35 kN then the armour (all armour except back) can attain an EN-1621-1 rating. Standard also includes other factors such as temperature stability and coverage area. The back protection standard is EN-1621-2. That standard rating is based on that energy being less than 18 kN (EN-1621-2 Level 1) or less than 9 kN (EN-1621-2 Level 2).

When tested to the procedure defined in the standard, the two levels of performance are:
