Micro-Lock Air Unisex Back Protector MK2

Planet Knox

£99.99

Knox Micro-Lock is the softest protection available. This makes it perfectly comfortable to wear all day. Micro-Lock Air back protectors also contour to the body and they use SMART technology and properties. These keep the armour super soft to touch, but it locks when impacted. This locking action increases the amount of impact absorbed by the protector, and therefore reduces the amount of unwanted energy passing through to your precious back.
