***Reason I bought It
I have never been a fan of stuffing a bunch of pillows in a stuff sack and using it as a pillow. I know that it is the backcountry and a night of sleep out there is not going to be perfect, but a good pillow will go a long way for me.
The weight is good. For me I can justify it because I use it with the therm-a-rest z-lite so I can spare a few more ounces in my sleep system.
I think it is worth it, but if you can find it for about $15 it would be a great value.
This thing really feels solid. The one way valve is amazing. You just breath almost once into it and it is inflated and the valve locks it off so that air does not escape it. Then, you just push the button and in a split second its deflated. This is an awesome design. It feels solid like it is going to last a long time.
My intent was not to sit upright and sleep - I wanted to lay down and sleep. When I bought this I had no idea if it was going to work for that. Basically what I do is have it about halfway inflated and put it slightly around my neck at an angle more like a traditional pillow. It works great.
