Best reusable water bottles: our tried and tested picks

The best reusable water bottles on the market can not only save you money but could also save the world from a lot of single-use plastic. Talk about a win-win!

Like the best workout clothes, reusable bottles can also be functional and fashionable, and we've found some of the best-looking ones you can buy right here.

They're pretty, but these bottles are also practical. Often made of stainless steel and with double (or triple) layered insulation, you can use them to transport far more than water. Whatever you put in them will stay hot or cold, whether that’s water, tea, or wine. (Hey, we're not judging!)

Some of these bottles can be used for hiking or long journeys, with screw-top lids designed to protect you from spills. There are also some great options to use at the gym, with easy-flip lids and mouthpieces designed to sip. One of our top picks comes with an in-built filter, which will make sure your water is fresh and clean. 

The best reusable water bottle for you really does depend on your lifestyle. If you need something easy and compact to throw in your bag alongside your gym gear and one of your best yoga mats as you head out to a fitness class, you can choose one of the smaller bottles in our guide. Adventuring types will love the larger options—the biggest one on offer here is 64 ounces. For the very best reusable water bottle for you, keep on reading!

Best reusable water bottles: tried & tested

it's no secret that we've been fans of the Chilly water bottle for years—the brand’s plastic-free bottles keep your water cold and tasting fresh for up to 24 hours. If you decide to put hot water in your bottle, it will stay warm for 12 hours thanks to the double-layered stainless steel design.

Chilly's offers four sizes—9oz (260ml), 17oz (500ml), 26.4oz (750ml), and 60oz (1.8l)—but not all of its extensive color and pattern options are available in all sizes. There’s a design for everyone, and you can even buy a charity bottle and a portion of your payment will go to eco-friendly charities. These bottles can’t be washed in a dishwasher and thanks to the narrow neck design they’re a little fiddly to clean, but other than that, they're unbeatable. 

The Brita Premium Filtering Bottle comes in a range of six attractive colors and two sizes (26oz or 36oz). It's made of BPA-free plastic that, while durable, will never last quite as long as a stainless-steel alternative. 

That said, for avid travelers or those without the best tap water at home, this filtering water bottle is a game-changer. It comes with a filter in the straw which needs to be replaced every two months for the freshest taste, and it’s designed to remove chemicals like chlorine from your drink. 

With a carry handle and a flip-up lid, we think this water bottle is one of the most versatile you can buy. Because of its straw design, it’s perfect for use at the gym and on the go. The lid is leak-proof and it will fit in most car cup holders, making it great for road trips. 

Available in 11 great powder-coated finishes, this reusable water bottle from Hydro Flask is ideal for those with active lifestyles. Because it has such a large capacity, it will see you through hikes, bike rides, and other outdoor activities with no spills or fuss. This bottle has a wide mouth that makes drinking a little more tricky, but it comes in a huge range of sizes for any occasion. The smallest Hydro Flask is 18oz, but it’s also available in 32oz, 40oz, and 64oz. 

The Hydro Flask is made of pro-grade stainless steel that won't give your water a funky taste, and because it’s insulated, it will keep cold drinks fresh and hot drinks steamy. 

The Adidas 18/8 Water Bottle not only looks sporty but it’s also got a great design for use at the gym. With an insulated stainless steel design, you'll get the same hot and cold insulation as some of the other bottles in our guide, but this one also offers a lid that’s great for sipping. Simply flip up the lid of this bottle to take a drink as you’re running or working out, and clip it to your gym bag on the way home.

This bottle comes in either 20oz or 32oz sizes—both are pretty large and offer plenty of capacity to see you through most gym sessions. It's also got a range of color options on offer.

The Corkcicle comes in countless color options, with funky two-tone and classic stainless-steel finishes on offer. The canteen is triple insulated and its screw-on leakproof cap and flat, ergonomic sides are distinctive and carefully constructed. Because of the tapered design, it won't slot easily into your bag like some of the other options here, but if you don’t mind its somewhat awkward shape it’s got a lot of great features.

You can't talk about reusable bottles without mentioning S'well. The omnipresent brand had gone from strength to strength and is ACTUALLY rather really good. 

When it comes to design, the S'well offerings come in so many different colorways, patterns, and finishes—not forgetting styles too—that would mean there really is something for everyone. 

Whether its for a solo gym trip, your everyday bottle or a big park get-together, there is a wide selection of sizes available, from the original (pictured), travelers  (the ones with the wide-mouth), roamers (the big ones for sharing) and kids (the ones just for them), you're sure to find a S'well bottle for whatever occasion you need.
