Thread: Mid-winter sleeping systems

I use one of those dirt cheap survival sheets under my mat then I have my thermal blanket - dont camp in winter without it - its a type that used in old folks homes - under patients don't let moisture thru - light as - on top of sleeping mat then fold over the top of sleeping bag- comfy as - but that thin survival sheet under the mat does give a good degree of insulation from cold coming up thru from the ground - both the blanket and survival sheet take up no room and are light as - only down side is those survival sheets dont last but they are cheap
