Who came up with this, and when? I got the impression that this is a relatively new invention, even though it seems so simple that it makes you wonder how this could even be something new. You still meet people who have not heard about it, even though they have a modern sleeping pad that could be shnozzled.
Love the shnozzle.
They’re also great because they don’t introduce moisture to the pad like you breath does, which minimized the possibility of mould or mildew, which is especially important if you have a down filled pad.
