Comfortable, compact travel neck pillow with an inflatable air core, synthetic filling, and soft microfiber cover. Ideal for air travel, buses, and trains. Features an ergonomic shape and a hidden, adjustable front closure with snap buttons to prevent the head from leaning forward. With the help of a one-way valve with a flat closure cap, the support effect of the pillow can be quickly adjusted to individual needs. Instructions for inflating the pillow with the new valve (yellow button): 1. To inflate the pillow, blow into the opening a few times. To ensure the valve holds the air, press the pillow once afterward. 2. Close the valve with the closure cap to completely prevent air from escaping. The valve is closed when two clicking sounds are heard. 3. To release air or adjust the support effect of the pillow, simply press the yellow button.
