The Pillow X has an interesting x-shaped design helps centre your head and neck keeping you comfortable. It is light, packable and super easy to use so it is ideal for any trip.
Klymit says:
Supportive and comfortable at a weight you won’t even notice. The Pillow X is a backcountry sleep necessity and may be the most technically advanced pillow ever developed. The advanced, self-centering X design positions and cradles your head for supportive, stable comfort. Durable 75D at the bottom resists abrasion and punctures, and the lighter 30D top sheds grams and ups softness.
Klymit's Pillow X takes just a couple of breaths to inflate, it is lightweight and has a nice small pack size. It is ideal for any camping trip. As with any air pillow, it is best to play around with how much air you want in it to make it as comfortable as it can be for a good nights sleep.
It works particularly well if you sleep on your back a lot as the 'self-centring head and neck support' or the x-shaped folds in the pillow really do work well to get you comfortable. I move a lot and generally sleep on my side for most of the time but I still found it comfortable enough.
