I finally decided that I was too old to sleep on a rolled up jacket on backpacking trips. This pillow provided an excellent and affordable way for me to keep a light pack and to sleep better. It folds up smaller than a pair of socks. It inflates to a size large enough to keep the cricks out of my neck. I love it.
The pillow does not slip and slide through the night. It can fit inside the hood of my sleeping bag or sit nicely underneath. It is comfortable. It is affordable.
