This is the bottle that established Nalgene as a household name, and remains the company's bestseller. Hikers and other outdoor types have used Nalgene bottles for over 20 years, which is why most backpacks have a side pocket designed to accommodate a Nalgene. Its design, though simple, boasts more than 50 years of manufacturing fine-tuning that's resulted in a remarkably durable, leakproof bottle that's guaranteed for life. Measurement markers printed on the side of the bottle help you track your fluid intake, and are also handy when mixing beverages in the bottle. Available in a variety of colors, the bottle has a large opening which easily accommodates ice cubes, fits most water purifiers and filters, and makes hand washing easy. An attached loop-top never gets lost and screws on and off easily, while offering a handy finger hold when on the move.
