Is this bag mateable with another exact bag? That is, can you zip two of these bags together to create a double sleeping bag?
I have not tried this, so I don't know for sure (only have one).
I do not know. I have never tried to do it
It is and is one of the reasons we bought theses bags.
I'm not sure. I honestly haven't used it because its too heavy. I bought it because it would keep me warm. I wasn't considering the size or weight when traveling with it. It may work but I'm not sure.
