insulated sleeping pad

Stephenson’s Warmlite: Jack Stephenson invented the inflatable insulated mattress way back in 1958. Their Down Air mattress (DAM http://warmlite.com/down-air-mattress-alone/) is now available in a stand alone for US$140 in a variety of sizes. One of the things most to like about it is its width – it comes in from 22” (56cm) through to 28”
