The Klean Kanteen Wide 40 oz water bottle had been a favorite of ours in the backcountry for years.   The 2 most important features are that it fits a standard round nesting cup or stove, and the fact that it is not insulated means we can use it on a fire. This bottle is perfect for our 1 is none and 2 is 1 logic when it comes to gear.  Cook soup or tea, purify water and use it all day as a very durable water bottle.  The wide mouth will fit most backcountry water filters and makes it easy to clean.  The Loop Cap also has a stainless-steel inside, so your favorite beverage also never touches plastic.  Want to change the cap, no problem there are many options you can add on.
