The wide mouth version by Nalgene might just be the most versatile stainless steel water bottle available. Made from Guyot Design surgical grade 316 (18/10) stainless steel it is virtually bulletproof in a 34 ounce format.
I picked up one from The Canadian Outdoor Equipment Co online store after doing some research. The versatility of the bottle is in its construction; a heavier and unlined stainless steel without any seams. The wide mouth version makes for easier cleanup but also can be used on heat sources for boiling water or preparing food. That is where it excels. Unlike the competition it has a pronounced bottom lip that facilitates the secure fastening of a wire, small chain or paracord when using the bottle suspended over an open fire.
I also like the fact it fits into my GSI cup for ease of transport and also fits most standard water filters on the market.
Awesome bottle. A must for any pack.
