Narrow mouth design is great for drip free drinking. Highly resistant to staining and odors.

Incredibly durable and versatile the Nalgene Great Outdoors Explore 32 oz. Narrow Mouth Water Bottle is a favorite of everyone from commuters to expedition climbers. Commuters like it because the narrow mouth allows for drip free gulps while negotiating hot afternoon commutes; and mountaineers like the virtually indestructible polycarbonate material because it holds boiling water and withstands repeated knocks and drops.
