The jungle bag is square shaped so it can be opened up quilt style and has just enough Travelsoft insulation to keep you comfy. There is a roll away mosquito net which can be zipped over the face to avoid biting insects in the night. Treated with an antimicrobial agent, this bag will reduce the growth of bacteria and unpleasant whiffs when the bag is not able to be laundered due to being on an extended trip. At just 900g, it packs up smaller than a coconut!!!
