The original Nalgene water bottle, the trailblazer.

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 32-ounce ( 1 litre) wide-mouth is your water bottle. Made from BPA free plastic. 

There’s a reason why Nalgene hasn’t changed its design in decades – because it works (extremely well). Leakproof and wide enough to accept ice cubes.
