The Touchdog Immortal-Trek Travel Dog Bed is composed of a silky-smooth sponge-like material that is entirely waterproof coated that wicks-away liquid. This dog bed is inner-lined with high-density polyfill that provides complete comfort when lounging. Perfect for travel, this Immortal-Trek bed features an embroidered side handle bar for convenient mobility. Waterproof micro-gripped backing on the reverse makes it durable for outdoor surfaces. The side of this travel dog bed is also geared with a zipper that when opened enables the inner cushion to be removed and is further machine washable.
