The Klean Kanteen Wide water bottles is one of our favorite due to it's large size, lightweight single wall construction and wide mouth.
It is the most versatile waterbottle we have used. Just put in on the fire and boil some water in it. When the water is out, lay it down on the hot coal and fry some bacon on it. Or do as the most of us, just use it to keep your beverages fresh.
Included Loop Cap has a stainless steel base so your favorite beverage never touches plastic.
