The comfortable air mattress can be inflated by mouth, hand pump, regular double action hand pump together with the inflation reducer, or a waterproof bag with pump can be used (pumps not included). When inflating with a pump or bag, moist air from the lungs does not get into the mat, which insulates less and contains microorganisms and fungi. The mat excels mainly in its small volume when packed, its low weight and high comfort. Especially suitable where you need to save space and weight and at the same time do not want to compromise on comfort. Very popular for cycling and climbing.
