Wondering why the homeless members of our community choose to sit on cardboard, especially during cold months? They do so in order to prevent loss of body heat. When sitting on a cold surface you need to be able to put something between your body and that surface. The closed cell foam pad included in the VLES GO-bag is a great barrier. The pad can also be used for changing a baby, kneeling on, a board game playing surface, etc. The bright green color makes it easy to see dirt so it can be properly cleaned before being put away.
