Once a material most commonly used on billion dollar super-secret spy planes, titanium has found its way into consumer products these days like collar stays, iPhone cases and now even water bottles. At a mere 4 ounces when empty the Exotac titanium water bottle, or TiBottle, is not only the lightest metal water bottle you’re going to find, but probably also the toughest.
The bottle is actually made of 3 separate pieces of titanium which have been welded together, and it holds about 650ml of liquid. And as if being made from titanium wasn’t cool enough on its own, it also allows the TiBottle to be heated directly on a stove for boiling water or preparing a meal while camping. But on the flipside, because it’s made of titanium the bottle also starts at $75, with finish and matching cap options adding to the price.
