We take great pride in the quality of each and every Polar Bottle water bottle we produce and distribute from our Boulder, Colorado warehouse. Every bottle goes through several levels of quality control before it is shipped out and the bottle is designed to last for years. That being said, we understand that things happen; bottles can break or customers might simply be unsatisfied with their purchase. With this in mind, we offer an unconditional lifetime guarantee on all of our products. If anything ever happens to your bottle or you are otherwise unhappy with the product, give us a call or drop us an email and we will take care of you. Guaranteed.
