Nalgene Wide Mouth Sustain 32 oz (with On-The-Fly Cap)

Nalgene's 32oz On-The-Fly bottle has a leakproof loop-top that swings open wide to reveal a contoured, high-flow drinking spout that's easy to fill at the fountain or sink. One-handed push button for easy open/close; locking bail for ultimate insurance against leaks. Thoughtfully made from Tritan Renew.
