Meet the iconic Nalgene bottle, now even better for the planet! This 16oz narrow-mouth bottle is part of their 'Sustain' line, made with Tritan material that's BPA-free AND contains 50% plastic waste (pretty cool, right?). It's the same super-tough, leak-proof, and dishwasher-safe bottle Nalgene is famous for – it can survive just about anything you throw at it (or drop it on). The narrow mouth is great for sip-by-sip drinking without big splashes. It has a loop-top lid that's easy to clip to a backpack or gym bag. The side is clearly marked with ounces and milliliters so you can track your water intake. Made in the USA. It's perfect for hiking, the gym, school, work, or just daily hydration. Durable, practical, and eco-conscious – a bottle you can feel good about using for years.
