Foldable water bottles – we’re sure you’ve seen them. From the collapsible water bottle Tesco have on sale, to the fancy designer ones you scroll past on Instagram. They may be the best travel water bottles, but they’re just plastic nightmares, right?

We sure won’t deny that plastic and silicone are (often) bad materials… but are they worse than the millions of single-use plastic bottles we waste? No, they aren’t even close.

If you want to make small steps towards an eco lifestyle, these best collapsible water bottle reviews are a great place to start.

Remember, going for a reusable bottle means you can save an average of 156 plastic bottles annually. Even if some reusable bottles are made of plastic they are still great eco friendly bottles!

Also, all the foldable water bottles from this article are BPA-free and made of food-grade materials. No health issues here!

Squeezable Nomader Collapsible Water Bottle

The Nomader is the most flexible water bottle on the list! It holds 650ml of hot or cold water and rolls up when you’re finished. It’s free of BPA, BPS, PVC, phthalates, lead (obviously), latex, and other harmful chemicals.

More info on this bottle and Nomader here.

We love it because: This folding bottle goes in the freezer, fridge, airplanes (no metal parts) and dishwashers without a single complaint! No surprise this bottle also has its spot into our selection of the best eco-friendly water bottles.

ONEISALL Collapsible Sports Bottle​

One is all you need here! Although it looks like it won’t hold the most amount of water, it’s actually quite clever. The easy-to-grip hourglass shape allows for the 500ml silicone bottle to compress super small.

We love it because: It’s a mere 4cm deep once it’s compressed and slides right into your jeans pocket.

Que Will Love This Collapsible Bottle

Collapsible, lightweight and made of 100% food safe (BPA-free silicone), the Que is a modern, twisty take on the silicone water bottle. It’s as sleek as the Sho bottle, but smaller! It holds 568ml of hot or cold water.

We love it because: the neck is wide enough to fit in ice cubes and is topped with an 18/8 stainless steel lid – because why top an eco silicone water bottle with more plastic?

HYDAWAY Collapsible Water Bottle UK

The beauty of Amazon is finding American innovative products with UK shipping. The HYDAWAY holds 511ml and presses into a 1.5 inch disc. It’s planet friendly and available in numerous colours (we love Timber Green).

We love it because: the lid is entirely BPA-free, food-safe silicone and ensures there are no leaks in your bag throughout the day.

Sto-Cup Collapsible Water Bottle with Filters Too!

A premium, rollable water bottle that holds 750ml. The Sto-Cup is a simple design with an annoyingly plastic lid, but happily the silicone body will last years longer than plastic thanks to its durability.

We love it because: the water filters enable you to use tap water without any safety concerns, instead of filling up from purified bottled water.

Nalgene Collapsible Water Bottle for Camping

Okay, so it’s near the bottom of the list. Here’s why: it’s plastic! PE plastic. Making it is, by definition, terrible for the environment… but it is recyclable and reusable, not to mention entirely food-grade safe. This foldable, scrunchable container type bottle holds 1 litre, 1.5 litres or 3 litres.

We love it because: it’s a great one for hiking and camping when lightweight belongings and  backpack space is a priority.

Vapur Collapsible Water Bottle

Yep, another PE-lined collapsible plastic bottle. This one holds 1 litre and is dishwasher safe – did you know dishwashers waste less water than hand washing? It’s a great roll up water bottle to have in your bag for emergencies.

We love it because: the inside is odour, taste and stain resistant so you can fill it with fruit juice and not worry about funky notes lingering!

Psst! Most of these have free delivery with Amazon. Pick one now and you’ll be set for a lifetime.
