The Polar Bottle dual-wall insulation design features a reflective foil layer between an inner and outer bottle to keep liquids cool twice as long as standard water bottles. The foil layer reflects the sunlight, while the inner and outer bottle create an insulating air barrier. Polar Bottle is the originator of this design, and remains one of the top performing insulated squeeze bottles on the market.


With a 42oz fluid capacity, Big 42 is among the highest volume squeeze bottles on the market. Based on our research, it is also the only dual-wall insulated bottle of this kind on the market.
