Nalgene Sustain Tritan BPA-Free Water Bottle Made with Material Derived From 50% Plastic Waste, 32 OZ, Wide Mouth, Amethyst

Over the years, I've had about four of these in different colours. The only reason I've ever replaced them is because I appear to lose a water bottle every 2.5 years!Really nice vibrant colours that don't fade or chip like an anodised bottle would + it's dishwasher safe with no noticeable degradation to quality. The quality on Nalgene has always been exceptional and lasted many many hiking trips + every survives every day life. 1L is the perfect size for me.While some may say ~£20 is steep, I have had no problem ordering another without a second thought on price the instant I realise I've lost one.

Really love using this! It's big enough to fill and use in an exercise class. I have been using it mainly in hot classes (like yoga) and it might be to do with the rate I am drinking in the class, but I find water stays cold for the 50 minute class. I've also tried it with hot coffee to save carrying another travel mug. It does keep the drink hot for about 15-20 minutes but the nature of the material means it does not stay hot for long, so it won't keep your hot drink if you wanted it in an hour but using it to drink immediately and on the go is perfect.

Lovely colours, super durable, washes well in dishwasher, worth the money.

Love the size, which is great for getting me through a workout. The loop attachment on the lid makes it easy to carry as it’s sturdy, and the quality of the bottle feels great. I’ve found it to be leakproof so far, the only thing I’d possibly do different is buy the narrow neck as swigging from a bottle with size a wide neck, especially during a workout, can sometimes be a little messy…

Great product!!!

Writing this review a year later and I still love this bottle. It’s now covered in stickers from my travels. has been beaten but still holds strong. No leaks and super cute.

I wanted a bottle that was easy to clean. This is perfect it has a wide neck so can easily wash the neck with a sponge and avoid bacteria. I have ordered a second one. I am not keen on ones that go in dishwasher.

Great bottle, good quality

The best of the best. Durable and easy to clean.

Asla koku yapmadı bu benim için en önemli kriterdi

I’ve been using my Nalgene Wide Mouth Sustain bottle in the amethyst color almost daily, and I’m genuinely impressed. The bottle’s wide mouth makes filling, cleaning, and adding ice so much easier, which has been a big plus in my routine. The amethyst color is subtle yet distinctive—makes the bottle feel a little more “me” than a plain clear one.If you’re looking for a high‑quality, durable, everyday water bottle that combines functionality with a nod to sustainability, this Nalgene is a fantastic choice. Stylish in amethyst, built to last, and something I reach for every day. Strongly recommended!

Great quality and met all the criteria in the description.

La qualité Nalgene n'est plus à démontrer.Très belle gourde de 1 litre.Capacité, étanchéité et ergonomie du bouchon, matériaux...Tout est au top !Je conseille sans le moindre doute.
