It would be easier, cheaper and lighter to use something you already have in the pack. When I put my mind to this the conclusion felt pretty obvious.
By Jörgen JohanssonWell, what can be seen in the photo is not really something I already had in my pack. It is a short length (10 cm/4 in) of ordinary garden hose. To one end I have added enough layers of duct tape to make it fit snugly into the recessed nozzle where you inflate the Synmat.
|I found it fairly easy to add the right number of layers for a snug fit with enough friction to stay in place under pressure.|
|First thing; tie a knot on one of the legs of the pants.|
|I grabbed a piece of elastic that happended to be handy.|
|You just insert the hose at the bottom of one pants leg and twist the elastic a number of times around to assure a snug fit. Make sure that this does not mean that fabric inside will block the hose.|
|Rolling the pants leg, pressing the air into the sleeping mat. It took about 2,5 pant fills for my sleeping pad.|
