Hammer Nutrition Purist Water Bottle (22-ounce)

Hammer Nutrition's Purist Water Bottle is a BPA-free bottle that offers a taste as pure as drinking from a glass, with all the advantages of a flexible bottle. It features a protective barrier inside that prevents odors, stains, and mold from permanently attaching; the Fixy cap with a fixed, self-sealing Heart Valve to prevent leaks; and a see-through strip so you can see how much liquid is left.
