Nalgene Sustain Tritan BPA-Free On The Fly Water Bottle Made with Material Derived from 50% Plastic Waste, 24 OZ, Clear with Sprout

Excellent water bottle. Easy to fill and clean, dishwasher-proof, and not a single leak after 6 months of daily use. Still looks as new as the day it was bought.

This is my second Nalgene water bottle as the first is so good at being completely leak free. The only reason I'm buying another is that a small discolouration (mould?) has formed in the clear rubber seal inside the lid. It's difficult to clean that piece and also difficult to remove it to dry properly. Having said that, the old bottle is 10 years old, and has survived everything I've thrown at it including being dropped several times on hard surfaces without splitting or leaking. Hopefully the new one is just as good. I suppose my only complaint would be that it was near impossible to find replacement parts. I couldn't find a replacement seal and though there were replacement lids, I couldn't find it in green and it was nearly the same price as a whole new bottle anyway.

I absolutely love these bottles - they do not leak and are durable. I only have to buy a new one every two or three years and I use these everyday in the classroom as a teacher!

I have now bought three of these. I always used aluminium SIGG bottles but they have disappeared from the market, and these bottles are the next best thing. The wide neck and simple yet effective design makes these easy to keep clean. Their only fault is that they don't survive being dropped onto rock from more than a metre when full.

Great water bottle, fits in cup holder of pushchair and can still get a decent fill.

Love this bottle
