When going to camping, you cannot take many objects with you. If an emergency happens and must stay over, you must bring with you a big sleeping bag, which covers a lot of space and weight.
FillSleep is a simplified sleeping bag that can help you save space when camping. You just need to fill the bag with mountain resources such as dried leaves and grass, keeping you warm when sleep.
