Abstract: A bodyboard/snowboard includes a bag, an inner chamber and a protection layer. The bag has an opening thereon and the inner chamber has an air valve thereon. The inner chamber can be inserted in the bag from the opening. By inflating air from the air valve, the inner chamber will be puff up till it integrally fills up the bag for using. By deflating the inner chamber from the air valve to be empty, the inner chamber's bulk will be lessened in order for rolling. Therefore, the bodyboard/snowboard is easily to carry and store. Furthermore, the protection layer can extend the available life and strengthen the surface contacting with outer force. Consequently, the bodyboard/snowboard can be used when surfing or skiing.
