Mine weighs 18.4 oz, and it measures 60x24x2.5, mummy style. It's double the weight of my neoair short, but I had already decided I wanted something longer, somewhere in the 13 oz range, and wishing I could find something a bit wider. This KookaBay one is all that, plus the down, so I figure I've really only increased the weight about 4-5 oz.,including the pump at a little over an ounce. Didn't somebody once say another pound or so wouldn't even be noticed? Dr. J, I think?!!!!
If you contact Bender and tell him the specs you want and ask for the price and weight, he'll tell you.
