My sister asked for a small go bag that would fit a single book with room for the typical things (cards, phone, mints). I’ve browsed some options(including bags that incorporate a book strap) but wanted to check what other people who carry books around typically prefer before committing to something.
Maybe something like a Tenba DNA Messenger 13 or 16 would work. Its padded and will easily fit lotr with room for snacks. I bought mine for a camera but use it for everything.
