A handy backpack made from heavy-duty canvas cloth and is big enough for all that stuff that is too big for your belt-pouch. The straps are lined and fitted and can be adjusted in their length. The entire backpack is lined with cotton and it has a small bag sewed in the front.
I used this rucksack to carry waters, character sheets, money, you name it. I also carried everyone else's. It's cute, bit small for bigger things, but overall It's both high quality and durable and gets the job done.
