With the built-in pump, inflating this travel neck pillow is a breeze - simply press by hand instead of blowing with your mouth. It only takes about 30 seconds to fully inflate. Deflating is just as easy, allowing you to roll it up and store it in the included travel pouch for added convenience and comfort during your travels. Plus, it's much more hygienic than traditional mouth-inflatable pillows. Despite its generous size of 15 x 9.9 x 4.7 inches, the pillow only weighs 3.5 ounces. Material: TPU. Weight: 3.5oz.
