These 32oz 1 litre Tatonka 18/8 Stainless Steel Bottles look quite good and appear to be very lightweight for Stainless Steel so must be very thin walled at 210 grams (7.4oz). This compares to the Sigg Aluminium at 145 grams (5.1oz) and the Guyot Designs Wide-mouth 32oz Stainless Steel at 348 grams (12.1oz)

Insulating covers are available and will help prevent the the bottle getting the inevitable dents. Although looking at the bottle shape and size the SIGG Neoprene 1 litre covers would probably fit as well

While tooling around the web I came across a double walled stainless steel GI Canteen. I had to get past the foofoo advertising for it but it fits a need many people on here have looked for

I looked at both products and was impressed. It looks like the Tatonka 18/8 Stainless Steel Bottles are sold in the UK. If so, a high cost in shipping to the U.S. There are several U.S. manufactures of stainless steel water bottles (the US Canteen as one of them) on the market like Thermos, Thinksport and Camelbak, and all are insulated, a plus for camping, hiking, etc.

Be aware of Sigg, they have lost their credibility with the deception of their BPA lining in the aluminum bottles, linking to health issues and ban consideration in a few states.

Interesting idea. Though I'm going to pass on the man-purse carrying case.

Oh yeah, way to bring up a blast-from-the-past post

This is my next choice in water bottles:

Not meaning to sound personal, but I've always liked that idea for carrying a canteen, like you see in the old explorer/tarzan type movie.

I replaced my very old battered Siggs with these http://www.innate-gear.com/product-info/fresco/fresco-v2

Mainly because MEC were selling the plain ones for $4 CDN (about 75c US)
They are stainless with no liner, the thread at the top is plastic so your lips don't stick to it when cold like a Sigg.
And the lip wide enough to get ice-cubes in - it's supposed to fit Nalgene bottle filters.

Downside is the wide lip spills water down your chin - like Nalgene bottles do. And the wide thread means you have to be careful not to cross thread.

I agree, it was terrible how people who drank 6000 gallons of water each day from their bottles suffered medical issues. Luckily drinking less than that is no cause for alarm.

Be careful or the BPA police will come looking for you!

(the BPA levels in water bottles don't appear to be harmful. The level of BPA hysteria surrounding BPA in water bottles does far more damage. link H2O is far more toxic at these levels than BPA)

Not in extreme cold you know.

I have them on each family member's BOB, plus in each vehicle. Having used them, my only concern (recently mind you) is sub-freezing temps and the filter itself freezing up.
