What can you fit into a 1L bottle that will make your kit the best there is?
I will allow for a metal cup to fit over the bottle if that is that way you choose.

[/quote]What I put in a 1L bottle for survival purposes is water; the only thing better than a 1L bottle is a 2L bottle, and so on.

Perhaps by now you have realized that an old desert rat is speaking; your situation in Canada's far off frozen wastes may be very different. In the American Southwest in the season that is coming up, water is the key component of survival; everything else is secondary. Frequently a one liter bottle is insufficient.

I use the lightest bottle possible for my bottle (either a foldup Platypus or a recycled gatorade bottle) and then encase it in a SnowPeak 700 cup. This gives me versatility - I don"t have to heat all my water at once - and a basic cook kit that works quite well on multi day trips. I will usually do my heating on a cartridge or alcohol stove.

A much cheaper alternative, albeit heavier, alternative to the titanium is a stainless steel cup, readily available from many suppliers
