It's easy to use as a mattress pump as all you need to do is open the base flap and connect the sleeping mat valve to the connection point. Blow into the bag, roll down the top seal and push the air into the mat. Do this 2 or 3 times then hey presto your mat is inflated. You can then use the bag as a dry sack or bag liner by closing the flap on the base.
