Manufacturer: Polar Bottle [all listings]

Polar Bottles' sports-style plastic squeeze bottles are formed in two layers with a sealed core of insulation that helps keep liquids cool. At just over 4.5 ounces, their 24-oz. bottle is extremely lightweight bottle and clearly it and the company's 20-oz. model are the least bulky of the "refrigerating" bottles on the market.

The bottle's flexible polypropylene construction is highly durable. Where some water bottles pride themselves on their ability to withstand blows, the Polar Bottle gives in gently, then reclaims its turf. The bottles were not damaged, or even scuffed, by any of our drop tests.

The insulating layer allows this bottle to outperform traditional sports bottles. For best results, chill water in the bottle overnight and then take it on the go.
