Thermo Tank: Insulated Thermos

An insulated thermos is a wonderful thing. Especially when it's in the shape of a water bottle and keeps your drink cold for 36 hours.

The Thermo Tank is one of the highest-rated stainless steel water bottles on Amazon. The thermos is made with double-walled stainless steel, and the steel is layered with copper. Thanks to this dual wall the bottle stays sweat free, and the shape is great for camping, hiking, and fits nicely in a cup holder.

Over 1,500 Amazon reviewers have given the water bottle a high 4.8/5 stars.
