I have been using one of these pillows for about 5 years now. It has been one of my staple pieces of gear, I have replaced many other things in my backpacking kit but this item really stands the test of time. Light weight and comfortable, even as I am transitioning to lighter and lighter gear, I can't ever see replacing or leaving it at home. The shape of this pillow is perfect for supporting my head and neck, whether I sleep on my side or on my back. The only thing you have to sort out is how much air to put in it. Too much can be uncomfortable. I also added a bungie cord to the corner holes so I can loop it around my sleeping pad so I don't lose it in the middle of the night.
I have been using these for 2 years now and they are simply the best backcountry pillows you can get. Lightweight, compact and comfortable. I have tried many other options, such as down pillows, compressible, and other inflatables. This is the best yet, the contoured design cradles your neck and head like an orthopedic pillow and you can adjust the size and firmness with air pressure. I wound up buying a second one at a MontBell store in Tokyo because hotel pillows where so hard. Now I keep one in my suitcase when traveling just in case.
This rolls up so tiny that I had to tie it to my pad to make sure I didn't lose it. It was great to be able to tie it down to my pad so it would not roll away as happens with rolled-up clothes or other pillows. Haven't used enough to test durability, but seems OK.
On a week long campout in the Boundary Waters when a fellow camper loaned me this pillow... Comfortable, easy to pack, lightweight, excellent product.... I am ordering one for me and my son this week... Not sure as of yet the durability, but for the one week I was absolutely impressed.
This pillow is awesome - super comfy, takes up virtually no room in your pack, it's big enough even for larger heads - you'll never sleep on your jacket again!
