MDinana,

One pair leather gloves, break them in before storing in pack.

Water purification tabs (Micropur MP1, or Potable Aqua ), or one of the electronic or pump style filters/purifiers. (I figure the tablets will fit better in an already tight pack.)

It lookd like you have plenty of,
12 trioxane tabs
1 package of Esbit fuel tabs (12)
but I do not see any type of metal container in the kit.

The GI canteen cup will work great, or something like the MSR Stowaway pots, or http://store.sundogoutfitter.com/Items/z...t%2022oz%2010cm may work if you can pack some stuff inside the pot, as they do not add that much more space. (you may already have this type of thing in the camping gear you mentioned but in a rush to Bug out/ Evacuate it may be better to already have this type of gear stored in the pack.

For the most part your kit sounds like it is well oriented for the 72 hr thing. If space in the pack is an issue there are a ton of bags that you can attach to the outside of your pack.
