The Nalgene Sustain Tritan Wide Mouth Drinking Water Bottle is just what you need to prevent dehydration and quench your thirst on any outdoor adventure. Nalgene makes a wide range of BPA-free reusable water bottles and containers to suit your personal preferences, needs, and lifestyle. So, whether you’re looking for a virtually indestructible water bottle for a backcountry adventure, or you want a clean, green way of storing your dry pasta, you’ll find a Nalgene product that gets the job done.

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 wide mouth is your water bottle. Completely leak-proof, continuous, straight-shouldered semi-buttress threads keep the bottle sealed tight. There’s a reason why Nalgene has not changed its design in decades because it works (extremely well). Thanks to a wide 2.48″ (63mm) mouth opening (32 fl. oz. model), you can easily fill the bottle with ice to enjoy a cold beverage.

A wide-mouth also fits most filtration devices. It’s marked with milliliters and ounces to allow you to make an estimation of your fluid intake. The convenient loop-top design keeps the lid securely in place and ensures that you do not misplace it. The Nalgene Wide Mouth Water Bottle is ideal for all your outdoor excursions. Made from BPA-free Eastman Tritan co-polyester material that leaves no after-taste or intake
