Nalgene has taken on Everest. Now they're ready for toddlers! Nalgene containers have stood up to some of the world's most extreme conditions. Small potatoes compared to small children. The Nalgene Sustain Grip 'n Gulp is tough enough to survive being thrown from a moving minivan, spill proof enough to compel parents to blame the rug stains on the dog, and odor proof enough to allow leftover milk to go undetected under the couch for months. Most importantly, it's a great way for little kids to reach new heights.
