If you’re looking for a water bottle that will keep you well hydrated, hold up against bangs, bumps, and drops, and not leak a single drop ever, then the iconic 32-ounce wide mouth is your water bottle. There’s a reason why they haven’t changed its design in decades—because it works (extremely well).

This bottle features a wide mouth that’s great for adding ice cubes, swabbing out the insides, and easy opening in colder conditions.

Features

• Made of BPA-free Eastman Tritan co-polyester
• Dishwasher safe on the top rack
• Superior impact resistance
• Suitable for both warm and cold beverages (-40 to 212 degrees Fahrenheit)
• Convenient loop-top design means you'll never lose the lid
• Wide mouth makes cleaning and adding ice cubes easy
• Opening accommodates most water filters
• Marked with milliliters and ounces for easy measurement

• hreads: 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.
