I think the Sigg bottles are lighter than PC Nalgene bottles. The aluminum fuel bottles are not coated on the inside but the water bottles are. I think they use a flexible glass coating on the water bottles which may or may not take the heat. Sigg recommended against cooking in their anodized food boxes but I can see no reason not to....except for cosmetic reasons and possible warpage. The water bottles on the other hand do present a reasonable issue with the coating...who knows what happens to it if heated.

You could elect to use the bare aluminum fuel bottles for water however...no acidic liquids though

I looked last night and I can’t find the glass coated ones anymore. They seem to have changed to a baked-on enamel coating while I wasn’t watching. I am intrigued by this idea and would try it if it were that our nothing.

To make an effective bail on a SIGG bottle remove your paracord shoelaces. A timber hitch with each lace pushed together will provide sufficient friction to lift the bottle. Now you stand up with potable water, turn and twist your ankle. <img src="/images/graemlins/shocked.gif" alt="" />

I was looking at some cheap ones at Sports Authority the other day. They appear uncoated on the inside. May have to do a little field testing!

Yes, you can, but the taste of the plastic liner is nasty! If you must I recommend burning the snot out of the liner and just leaving the aluminum behind.

After that nasty incident I've switched to titanium fuel/water bottles. I swear by them now!

I normally carry two water bottles. One is a always a 40 oz stainless steel Kleen Kanteen. You can thaw frozen water easliy next to a fire or boil water in it. It slips into a stainless steal or titanium cup for transport in my Maxpidetion DevilDog's canteen pouches.

Just curious... what's wrong with a surplus G.I. canteen??? Cheap, tough, and you can wrap a stove and cup around it in a belt/pack pouch.

I that's all you want, just get one of the stailess mugs with folding handles that is designed to fit over the bottom of a 1 l. nalgene.

Besides, you can get nesty sruprises boiling anythin in any narrow mouth vessel.

Not a thing wrong with a GI canteen. I was AD Army for 9 1/2 years, and still have 3 or 4 1 qt and one 2 qt.

Just looking for other ways to do things.

Options and back-up plans are good things.
