This universal tablet cover is designed to keep tablets warm and dry in freezing conditions. A built in heater automatically activates when your tablet's temperature is less than 40° F (4.5 ° C). The cover is made of polyester with a urethane backer and features easy to adjust Velcro closures. The design fits Zebra, Panasonic, Getac, and other tablets. It also works great for tablets using a keyboard bracket. If the screen gets dirty, simply wipe it down with a soft cloth and gentle cleaner or replace it with a new screen.
