This pillow works great. Weighs ounces and fits/stores right in the pillow pocket of my Big Agnes (crystal) bag(even when in the stuff sac.). Very comfortable and wide enough so your not searching for it all night. If I could ask for one improvement it would be to add another inch of height to it. However, I just stuff a shirt/towel under it and the height is good for me.
I've used this product at work mostly but did use it on a recent backpacking trip. I work in an ambulance and sometimes sitting in front is not comfy. I just inflate this thing and now i got something to lean my head on. It just takes two breaths and it fits in my work bag. Backpacking with it was great along with Big Agnes's sleep pad.
