I'd bring my Gerber LMF II as well...it was designed for helicopter egress after all.

If I knew I would only be out for 3 days I'd be really selective about the gear I took. It's most likely I'd take my personal PSK kit because it's smaller than a bar of soap and it's what I'm familiar with. It's got all the basics tinder, sparker, bandages, meds, firesteel, tape, etc. I'd likely supplement it with as much paracord or wire as would fit into said container so that I could give myself the best chance of being able to build a good primitive shelter that will keep me fairly warm without fire and shield me from prying eyes.
