Sustainability in your hands. Nalgene is proud to be the first to market with a new resin powered by next generation recycling technology that transforms plastic destined for landfills into high performance BPA/BPS free bottles. Our new Nalgene Sustain product line is made from 50% certified recycled content further offsetting the use of fossil fuels and lowering greenhouse gas emissions. The original. The trailblazer. The Sir Edmund of water bottles. 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 this is your water bottle. There's a reason why we haven't changed its design in decades—because it works (extremely well).
