CAT Back Cover for Apple iPhone 5s Active Urban  (Black, Pack of: 1)

An evolution from the active urban range and incorporating some metal elements making the product more desirable without compromising its protection attributes. The designs from active urban are understated and will appeal to a modern urban crowd. The range of cases for phones and tablets are made of saif which is an active material with unique shock and impact absorption properties. The saif is able to change its nature depending on the speed at which it is asked to react to impact. The material can have a soft touch and then stiffen up when impacted. These non-newtonian properties of the material means the harder you hit it the better it works, providing increased impact protection proportional to the force applied to it. Saif gives a step change in performance over typical foam energy absorbing materials and is much tougher than a normal foamed system, able to take multiple impacts without getting damaged.
