Hello,
Here are the contents of one of my survival kits that is an amalgam of the BCB Military and Ritter PSP kits and other odd bitts. Unpacked
http://tinypic.com/es6iyb.jpg , Packed
http://tinypic.com/es6kxe.jpg. Its contents are based on the 10 ESSENTIALS and my experience from many years of backpacking. While many folks pack their kits with purpose made survival items I try to select everyday, but compact, backpacking items that I would normally use while backpacking or day hiking. It contains; BCB tin, flint sparker, tinder, whistle, (4) safety pins, fishing kit, needle, heliograph, thread/fishing line, brass wire, Leatherman Micra, Suunto compass, LED flashlight, (2) small plasters (bandaids), (2) aspirin, antibiotic ointment, (2) large plasters, scalpel, (2) breast milk/water bags, (6) Katadyn water purification tablets, gum and coffee from an MRE. While I do not have the funds at this time to buy a kitchen vacuum packer, I plan on getting one to reseal the tin with a vacuum seal. However, I'll experiment first to see if any of the above contents have a negative reation to being vacuum packed.
