Nalgene | 48 oz Wide Mouth Silo Sustain Water Bottle

Large and in Charge for Your Biggest Adventures

Whether you're packing in for a multi-day backcountry canoe trip at Kejimkujik National Park, stowing it securely in the cockpit of your boat for a weekend on the water, or tackling the long, sun-drenched trek out to Cape Split, staying hydrated is non-negotiable. The Nalgene 48 oz (1.5L) Wide Mouth Silo Bottle is built for pioneers who need more volume to go further. Proven in the elements and engineered to take an absolute beating, this impact-resistant giant easily survives rough swells, accidental drops on the deck, and rugged Maritime granite alike.

Beyond its massive capacity, this bottle is a favorite for life on and off the water. The wide mouth easily accommodates ice cubes for blazing summer days and fits most standard backcountry water filtration units. Need a hot meal at camp or on deck? The bomb-proof Tritan Renew material can safely handle boiling water up to 100°C, making it perfect for stirring up quick ramen or oatmeal right in the bottle. Best of all, the leak-proof guarantee means it stays bone-dry even if it's rolling around in your pack or boat locker. Thoughtfully crafted from 50% certified recycled waste plastic, it delivers clean, odor-free hydration while helping to reduce your environmental footprint.
