As part of a larger emerg kit, I just made an SOS kit for a boat, designed to be small, inconspicuous, float and ALWAYS be on board, even if the larger kit is removed. I put key basic emerg gear (fire, water purification, signalling, sheter, navigation, first aid, light and food) in a Nalgalene. I put that in an aluminium can and duct taped them together. A metal vessel for boiling water was one of the key items I wanted to include. The can was cheap and easy.

Thanks for mentioning this ... I recently bought a Jeep and have been tossing my emergency gear in the back of the vehicle. My titanium cup is still in the garage - so I'll transfer it this morning.

You knew somebody VERY special there.
Nobody went through a rougher experience than those guys !!!

I have been carrying a gi canteen cup for .....wow..60 years. I was given one by my next door neighbor. He was a paratrooper during ww2.

He highly recommended it as the most useful item he carried. I agree.

Although the canteen I carry now is plastic, the cup is still a heavy duty
GI stainless steel one. Wish I still had the original but there have been several improvements.

Will that stainless steel cup fit in the 10cm (not 12cm) Zebra Billy Pot?
