Nalgene® N-Gen bottles are extremely popular with outdoor enthusiasts, and have recently enjoyed a surge in general popularity. The N-Gen makes it easy to fill and clean the bottle, but it also makes drinking while moving very difficult. The water easily splashes out over the user's mouth and down his front.
SplashGuard to the Rescue!
The SplashGuard is a plastic insert which provides a smaller drinking hole, blocks the splash, is easily removed for cleaning, and is dishwasher safe.
