There are certain styles of travel pillows that can be deflated when not in use. These types of pillows are easier to carry and are lightweight. Plus, deflating is an easy process. At first, you need to take out the stopper from the plastic nozzle on the values. Now what you need to do is to press the base of the value on the pillow. You can press the pillow by putting in slight pressure using your fingers. However, it is important to pressure the pillow slightly; otherwise, the pillow may burst and be useless.
