Hey y'all, I'm planning on starting a thru-hike in mid-late february and need an effective, affordable sleeping set up that'll keep me warm at night. I currently have a 20 deg REI TrailBreak Bag and a Nemo Switchback, which I know won't handle those single digit wet nights. I don't have much intel yet on sleeping bags but I figure a 5 degree is gonna be what I need. I've been seeing a lot about Thermarest Xtherms and Xlites; those are pretty expensive but I'm not at all opposed to spending the cash for them. Any places where cheap used gear can be found would be greatly appreciated as well; I'm looking through the used gear forums on here and craigslist as well. I greatly appreciate everyone on this forum.
