Water purification

Cost about 20 bucks. Might be a good investment for when the SHTF.

This bottle is heavy, and gets heavier when filled. I carry mine empty and use the water tight properties to store fire tinder and other items. This bottle is also a little noisy when walking the water swooshes around. If you experience this mere formality just add a bandanna into the bottle and it will serve as a barrier for water movement. It took a little bit to warm up to this bulky heavy chunk of steel, but after some experience I have found it un-replacable as a kit item. It is a bullet proof item. The wide mouth accommodates cooking food. The container is probably the most difficult item to make in the wilderness. Considering that water is number one priority, this item is number one in my kit for its purification and water storage abilities.

Taking a look out there for stainless steel canteens, that can be used to boil water directly in the fire if need be, or as a billy can.

Does anyone have an opinion on these?

Klean Kanteen Stainless Steel Water Bottles (40oz, 27oz) - YouTube

Some people are fanatical about how things fit snug together. It would be common to nestle a round GI cup on the bottom of a SS bottle. If there is not a close tolerance the cup will clang around. Nalgene bottles are perfectly dimensioned to the standard size round GI cup.
It is best to have a large opening for food and cleaning the inside of the bottle. I have made char-clothe in my SS bottle and it works great. However, unless it is necessary to do so, use something else and save the hassle of cleaning the bottle. Sand from a stream is a good source for cleaning the inside of these bottles. I also carry a Billy-can to do the dirty work like char-clothe and collecting Pine sap. The primary purpose of my SS bottle is to purify water, so therefore I have learned to keep the bottle pure even though the bottle has multiple uses.
I hope these comments put some light to help you decide if this particular bottle is right for you.

The Klean Kanteen is a good stainless steel bottle, very comparable to the guyot but les sin cost. It may not be as thick as the guyot bottles but I can tell you first hand, I have had one for years now and it has never failed me. I keep this bottle as part of my scout kit in my haversack. Very easily thrown in a fire to make all your favorite hot beverages!

The Space Saver Mug fits snuggly over the bottom of a 1 quart, round Nalgene bottle (Dimensions: 8.5 in height x 3.5 in diameter on Nalgene bottle)

Think I am going to order the 40 oz Kleen Kanteen wide mouth, and both the cups - and see which one fits the best. If the Olicamp is too tight, I can always use the extra 3/8" space from the GSIR for fire starting equipment for max utilization of space.

Just bought two stainless cups, 18 oz, for $4.95 each at wallyworld. They are Ozark Trail brand, but look identical to the GSI cups. I've read on a bushcraft forum the Nalgene fits perfectly in them like the GSI.
