Waterproof cases are primarily designed to be ideal for any tablet owner who finds him- or herself using the device in humid or moist climates with above-quality protection.
Waterproof tablet cases are distinguished by an added layer of defense in the form of vacuum sealing. The good waterproof case should create a vacuum-packed environment to effective sealing in the tablet against the elements. Quality waterproofing technology even allows the user to submerge the tablet under water, and some specifically-designed cases include a small hand pump which removes unnecessary air and thus unwanted humidity.
Waterproof tablet cases are typically made of some sort of silicone, plastic or other flexible polymer materials. If the material is transparent, the waterproof covering may remain in place during active use. One minus here is a loss of some functionality, as holes for ports and jacks are typically not provided to maintain the waterproof seals and protect the tablet.
