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.

Anatomy of a Nalgene Bottle

• Threads: Nalgene bottles and caps feature continuous, straight shouldered semi-buttress threads for increased contact area on the surface. This allows for greater tightening force without stripping threads.
• Cap: Durable caps are designed and built to perfectly mate with their respective containers. There's no separate liner to wear, crease, fall out, or leak, and the seal ring is molded directly into each cap.
• FDA Compliant, BPA-free Materials: Nalgene bottles are molded from 100% virgin resin with nothing but FDA compliant colors added. Finished products are tested according to the requirements of the USFDA for food and beverage contact.
• Heavy-duty Walls: Uniformly durable walls are thicker and more resistant to failure than many similar looking, but lower quality bottles.
• Bottom: Inner corners of each bottle's bottom are curved for easy cleaning, and a plastic resin code is molded into the bottle for eventual recycling after years of sturdy service.
