Nalgene has made some changes to a fan favourite, retaining its iconic features and quality with a more sustainable approach.


When something is as much of an institution as Nalgene, change isn’t always welcome. Why fix something if it isn’t broken? The planet, that’s why!

Nalgene have taken a good look at their offering and made the decision to overhaul their entire range to be made with their new sustain material by the end of 2023.

Nalgene had been on my radar for a long time, I knew they were the bottle of choice for hikers, but I wasn’t really sure why? I was lucky enough to get a first look at one of the Nalgene Sustain bottles to report what the hype is about.

So What’s New?

Nalgene bottles have always been BPA free and nothing has changed on that front. We all know that BPA is bad, but what even is it? BPA is a nasty chemical used in some plastic and resin products that leaches out into the water. This is especially bad when exposed to heat, ever had a sip of your old water bottle after leaving it in the car? Bleh.

The new Sustain bottles are made with Tritan Renew, which derives 50% of its materials from plastic waste, the equivalent of eight single use bottles.

The bottles are as sturdy as ever, and can withstand boiling temperatures without taking a hit.

Same Great Product, Different Materials

Nalgene bottles are built to last, so if you’ve got a bottle from the 90s don’t be so quick to chuck it to upgrade to the Sustain range. After all, product longevity is a huge factor when it comes to sustainability. Whether looking at an oldie or the new Sustain Range there are a few key features to highlight.


How tough can a plastic water bottle be? These bottles are virtually indestructible. I had a guy tell me he used his one as a wheel chock to stop his caravan rolling once. Your Nalgene is guaranteed for life which gives you a pretty good indication of the brand’s confidence in its durability (maybe avoid telling them you ran over it with a caravan though, if that’s how it meets its bitter end).

Free from Harmful Chemicals 

BPA and BPS free. There’s a lot of other stuff that goes into plastic, the Nalgene Tritan formula is tested by independent third-party laboratories to ensure its safety.

Hot Water 

Don’t be afraid to pour some hot water in there! Many hikers use this hack to keep warm at night and use it as a makeshift hot water bottle. It’s also dishwasher safe.


The simple wide mouth design makes it easy to clean the bottle, to fill up when out in the wild, and to use with water filters. It also makes it easy to spill on yourself when you’ve trying to take a sip while driving. Just make sure you buy the Easy Sipper attachment for use in urban areas. It’s available in a load of fun transparent colours so you can see what’s going on inside, and keep track of your fluids with measurement markings on the outside.


Your Nalgene is guaranteed not to leak. This is important.
