Try checking this mat out, its the dogs do,dah's :-Thermarest Neoair. it is the buisness. or the Torsolite mat, these 2 are the best and lightest ive ever seen, but saying that Gelert have a newish one out that only weighs 520g and these are all self inflate. if you like to travel very lite then these are the ones, BUT the 1st one i mentioned is the latest and lightest and smallest packed in the world apparently, and costs quite abit too.
