Bests & Worsts Reviews from Amazon

Be careful of the weight advertised above. I suspect maybe that's the weight with a high vacuum applied. No matter how much I squish mine down, after the first use I'm consistently at 3.5oz. (I stow it much more tightly rolled than shown here - it unrolled a bit when I took the cover off to weigh it, but did not bring in any new air - I have the valve closed.) If you're a weight junkie, you can save 0.4oz easily. Just don't bring the storage bag (0.2oz) and remove the elastic strap (0.2oz). My sleeping bag has a top "rim" that holds the pillow in place just fine, and I can store the pillow in my bag when I roll it up, so I don't need either of these. That brings my final carry weight to 3.15oz. If you can look past the misleading 2.75oz detail, that's actually really good for a pillow. This is a very comfortable pillow and it has a great valve - way better than my sleeping pad! It has a small pushbutton that you can lock open or closed for inflating/deflating it completely, and if you tap it briefly makes it really easy to let out a slight about of air to adjust the firmness. I slept really well on this.
