Unlined stainless steel makes more sense. I wouldn't try it with a lined or insulated bottle.

One thing I will not skimp on when it comes to weight management is A proper cooking vessel. I have mentioned on another thread If weight is a major concern then using a Pot from a Mess kit works good. You dont have to dump out your water to cook your food or worry about if its actually safe to do so in the first place. Even Kleen Kanteens company suggests not using their water bottles for this purpose which if you think about it would reduce sales so Im sure they mean what they say.

That's why I like my good 'ol army chow cup. It's perfect for boiling water in!

I've never tried it, but everything I've read on the matter says it isn't safe. Apparently the pressure created can potentially blow out a weakened area (like the welded seam) of the bottle like a bomb.



Hmm,

This sounds like an experiment tailor made for Sheriff Blast!

Im Pretty Sure not safe in the KABOOM kinda way.


Well, 'kaboom' is relative. Considering we're talking about a few cubic inches of dry air, this would be the equivalent of (consults conversion table) about 10,000 ant farts.

As others have stated, as long as the bottle is not lined, insulated or double walled you should be OK. How much grass sways in the breeze of 10,000 ant farts...?

I wanted to embrace the stainless steel bottle concept but I just can't find one designed as I'd like, and the weight penalty drives me bonkers. Why the heck can't Klean Kanteen make a bottle with the standard 1 liter/32oz capacity? Jeez.

I now use an old school Nalgene bottle nested in a Trek 700 titanium pot. The total weight (7.5oz without the Trek lid) is much less than that of the Guyot 1 liter SS bottle (13oz) and it is more versatile IMO. The Klean Kanteen 27oz bottle with lid weighs about 7oz.

Since the Nalgene & Trek nest together closely there is almost no space penalty for bringing the pot. I don't carry the Trek's lid except on (intentional!) overnights. A little aluminum foil is enough to get by in a pinch.

I agree with you completely. If you want to save even more weight (and money) a one quart Gatorade bottle, and perhaps other brands, slips into the same space in a 700cc cup. Versatile and lightweight. You don't have to boil all your water if you don't need to.

Glock, thats what i do too. Came in handy today when my son brought a iced water bottle into the car, it was cracked and leaking. I whipped out the cup and voila, fixed.

I like metal because I could boil if I had to - Its another form of backup.

You can also keep liquids cooler on hot sunny days in a metal water bottle compared to a plastic one. The weight difference is marginal between a 40oz wide mouth Klean Kanteen and a Nalgene bottle i.e only a few oz difference. Wrapping the bottle in a wet hand towel such as Lifeventure soft fibre hand towel

then placing in a mesh bag will form an evaporative cooling system to keep the metal bottle contents cold on a warm sunny day along the same principle as this;
