I largely agree. If my tests are to pan out (sounds like from folks’ experience was on here that they will not). My idea was to use this supplementally, under the right circumstances for my “this may turn into an overnighter type kit”. As I mentioned in my post, weight savings I agree will be very minimal at best. Mainly brought it up because I had seen it done before, and wanted to get some feedback before running my own tests.
I’m gonna test them with my Borah bivy sack and I’m looking into down booties for my feet, as well.
This is the circumstance I have done this in before, multiple times in different seasons. I always keep my down pants, jacket, beanie, and UL bivy along with a small Sil nylon tarp in my pack. I have a contractors bag in my pack too. I prefer to hunt off my back, and keep camp with me, so usually have my sleeping bag.
The times when I've had to do this typically involve harvesting an animal when I'm a significant distance from a base camp, which I typically hunt from for 2-3 days before going mobile. I've slept out with the clothes on my back, my puffies, and feet inside my pack, with the contractor bag over it, inside my lightweight bivy. It's fairly miserable, even in in archery season, as I typically hunt at treeline in CO, in the later seasons its primarily a survival strategy, and usually involves being in an area that's too cliffy, steep or otherwise dangerous to get out of by headlamp, with an animal on the ground late in the day and at least.
I will typically build a fire in this circumstance to go to sleep as warm as possible. I have had to do this as late as 3rd rifle, although I have a lot more layers on, and in my pack during the later seasons. That was a cold, uncomfortable night. I did a lot of jumping jacks that night, and slept very little. But I also survived a below freezing night out in the open, no worse for wear. So as a survival strategy, absolutely. As a primary sleep system, no way. I like to let my cloths air out overnight, and sleeping in them every night they get stinky. Although I do use my puffies to make my 5 degree bag warmer when hunting late season. Cheaper than owning a dedicated sub zero bag.
