Well, aren't you rude. The point of listia is not to spend money. It is to trade and or barter. The only money that needs to go anywhere is shipping. If we all wanted to spend money,we would go to other sites. If you are gonna trash and bash people, could you at least use real words and proper grammar or at least english words. Now I must block you for being an idiot and trying to ruin a fun time for the rest of us.
how does it inflat its self -- its it a one time thing to inflate itself like a emergence life raft or what-- the air pressure has to come from somewhere -- explain more how it works --
the mat is for hiking has a valve that you open and it inflates by it self when inflated you close the valve when finished you open the valve again and roll it up from the other end and as you roll it up it forces the air out when rolled up close the valve and tie with the straps and store and it is ready for the next trip hope this answered your questions
