Difficult to do more light. The DayBag is an ultra-light 80g bag. With its 18L, you will easily fit your UFO, or your well-folded SuSi (rolled without AirPack 50/50) with a string harness and even a helmet depending on the size of the SuperLight glider you put there! Foldable on itself, you can also leave it in the back of the trunk of your car and use it to store your groceries, or whatever else you can think of!
