>>1738263My sleep system is some combination of the military one, an Outdoor Research bug bivy for most places in summer so I don't get bitten up or catch Lyme, and a Kelty Cosmic Down 20 for better packability cold dry conditions. So like, in hot high summer I'll just be in the bug bivy under a tarp, inside the military bivy unzipped just to have something over me. In the lower end of the conditions I'm talking about now, I'll be inside the green bag inside the bug bivy. If it's wet or like edging below 5C I'll add the military bivy, usually cutting the bug bivy at that point. Cold and dry I'll be in the Kelty and cold and wet, or super cold, I'll be in the black bag. I've layered all the military stuff before at about -13C and that was a little too hot actually but workable. All of that with foam sleeping pads, I've got the standard Therm-A-Rest and a random generic $20 one I got at a surplus store that's actually thicker and warmer, but doesn't even fold – I have to roll it up and cinch it down.
I was looking at splurging on a Sea to Summit Spark 40 or 50/liner down bag because it's just SO PACKABLE (pic related) to replace the green bag most of the time, and seperately thinking about getting a liner, because it's not great to be sweating into all this gear, then having to specially clean it and beat it up some doing so, or more often not cleaning it. And then I put the two together and wondered if I could make something work that's more practical and cheaper, if less packable.
Maybe I can't! But that's what I'm wondering here.
