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 wide mouth is your water bottle. There's a reason why Nalgene hasn't changed its design in decades. Because it works (extremely well).
The large opening on their wide-mouth bottles easily accommodates ice cubes, fits most water purifiers and filters, and makes hand-washing a breeze. The attached loop-top never gets lost and screws on and off easily.
