It's true, though this bottle is made of vacuum insulated stainless steel, it floats even when it's full! It's perfect for boating, taking on a fishing trip, or for taking to the lake or river. It comes with a rugged plastic outer shell with a built-in handle and roll-stops for added stability, TherMax insulation, a twist-and-pour stopper that lets you pour without removing the stopper, and an extra large drinking cup. Holds about 34 Oz. (1 L). Measures about 13.5" tall, 4" diameter at the base. Shipping Weight: 4 lbs.
