I'm looking for suggestions, advice, and general discussion about 72hr+ survival bags. I've started assembling mine, and would like tips from anyone who's got experience with it.

Ideally I would be assembling a bag that allows for an extended stay, assuming I can get fishing, snaring, or small game shooting to provide some meals.

Additionally, what do you think about packing a tent + sleeping bag onto an emergency survival bag? In theory I would keep them separate, but strap them onto my bag if I felt the circumstances called for them.

I've watched a lot of videos on the subject, but many of them seem to be missing the point of a lightweight bag for hoofing it into the mountains.

I intend to assemble it, and take it out for a 4 day stay in the mountains, and see how well it serves me. I live in the Pacific Northwest, so I'd be in the Cascade range. Probably on the cooler/wetter side towards Western Washington.

Thanks.
