Nalgene Silo Wide-Mouth 48oz

The Nalgene Silo Wide-Mouth 48oz is a 1.5-liter reusable water bottle built for outdoor use and everyday hydration. Its generous capacity and wide opening make it easy to refill at a spring or sink, while keeping your drink close at hand on camping trips, hikes or daily routines.

Constructed from BPA-free Tritan, this bottle resists stains and odors, so your water tastes fresh even after days in the field. The wide mouth simplifies adding ice cubes and makes cleaning a breeze, and its 28.5 x ø 8.9 cm profile fits most pack pockets and cup holders without taking up extra room in your gear setup.

Tritan is a durable copolyester known for its clarity and toughness, meaning the bottle won’t crack or cloud with regular use. Being BPA-free means it’s made without bisphenol A, a chemical some plastics can leach into liquids, so you can stay hydrated without worrying about unwanted contaminants.
