Multifunctional Use: This blow-up pillow can be used not only for traveling, camping, road trips, but also as a lumbar support for office chairs, headrest, recliners, and neck pillows for driving. It will be a great addition to your lightweight gear on the go. Ergonomic - When you sleep on your back, the sunken baffles in the middle keep your head in place without shaking from side to side; the scalloped bottom edge contours to your neck and comfortably hugs your shoulders. When you sleep on your side, its height makes your head and shoulder width level. You can easily adjust it to the height you prefer through the air valve, giving you a good night’s sleep on the trail. Industry-standard - Environmentally Friendly – Air pillows are made from high-density polyethylene (HDPE) which is a recyclable material. Heat, cold, and altitude can constantly change the air inside the pillow. How to prevent, inflate your pillow some hours before you go to bed. Then, just before retiring, top up the pressure to your preferred hardness level. Versatile: Whether you're sleeping on a hammock, a plane, in a car, RV, or under a tent, our travel pillow will give you a great night's sleep wherever you lay your head. Simply blow up the pillow in 3 easy breaths. With the Quick Deflate feature, you are able to adjust the firmness to your personal sleep preference. SIZE MATTERS: Our compact & lightweight inflatable camp pillow weighing only 3.5oz and packs down to the size of a soda can, but delivers BIG on comfort!.
