Best water bottles for hiking 2024: durable bottles for the outdoors

If you enjoy taking a walk outside, then the best water bottles for hiking make a great companion. Whether you're taking a short local stroll or setting off on an extended hike in a forest or park, carrying one of these durable, lightweight bottles means you'll keep hydrated.

Most water bottles aren't explicitly designed for hiking, though, which can make deciding on a container quite a challenge. To save you endless hours exploring stores for a convenient, easy to carry option, we've tested the best hiking water bottles around right now.

We felt that the Sigg Water Bottle Sports was the best option overall, combing a durable design with an easy-drink cap and costing around $25/£21. For the largest bottles, like the 85 fl oz/2,500 ml CamelBak Rogue backpack, you can expect to pay close to $75/£65.

Fortunately, there's a lot of choice out there to suit a range of lifestyles and budgets. To help you out, we've roundup up our pick of the best water bottles for hiking, including BPA-free plastic options and large, easy to carry kegs to keep you hydrated while out walking.

The best water bottles for hiking

The Sigg Water Bottle Sports is a lightweight, metal bottle designed for hikes, walks, and workouts. It can hold a sizeable 23.4 fl oz/750ml of water, but only weighs 5.7 ounces when empty, so it shouldn't add too much to your hiking setup. The bottle isn't particularly complicated; there's just the aluminum body and a screw-fitted sports cap.

But that simplicity is what we liked when we tested the Sigg bottle; all you needed to do was unscrew the cap, turn on the tap, and quickly refill your bottle. The sports cap is easy to drink out of, but it also keeps the water flowing at a consistent pace, so you never get overwhelmed with water when trying to take a sip as you walk.

Reusable bottles help reduce single-use plastic waste, but the Sigg bottle is also recyclable. However, the aluminum body does mean that the bottle gets extremely cold if you put it in a fridge or fill it with cold water. Depending on the conditions, this may cause condensation, too. But these issues aside, we found that the Sigg Water Bottle Sports is easily one of the best hiking water bottles available today.

If you don’t like the taste of tap water, then you’ll love the Brita Fill & Go Active. The 22 fl oz / 600ml bottle contains a filter that slots into the lid section below the sports mouthpiece. As you drink, water is drawn through the filter and it traps substances like chlorine that can affect its taste. 

The filters are replaceable, and you can also use the bottle without them if you need to. However, they aren’t fine enough to filter out things like bacteria and protozoa, so we don’t recommend this system as a way of getting fresh water from outdoor water sources. We really like the sports cap on this bottle, which makes swigging as you walk a less risky affair, and there are several colours to choose from.

It's a great value-for-money option for those who like fresh-tasting water while they hike, although we think it could do with being slightly higher in capacity. If you’re going on a longer hike, or you’re someone who drinks a lot of water like us, we’d recommend bringing another bottle with you.

The CamelBak Rogue Hydration Pack isn't a regular water bottle you can store in your bag—it's a 85 fl oz / 2,500 ml water bottle backpack instead. This makes it ideal for hiking, long runs, or even days out when you want easy access to water. The Rogue Hydration Pack comes in two parts; a lightweight backpack with small, secure pockets and a refillable, removeable hydration reservoir inside.

There are hard plastic hooks inside the bag to keep the reservoir's opening in place for easy refilling, although we found that it was often quite challenging to close the lid without water spilling out if you've filled it to the top. Once you've got the backpack on, a tube extends across your shoulder with a lockable valve at the end for you to drink out of.

You sometimes need to suck quite hard to make the water flow, especially when you're getting close to the bottom (we found that using one hand to compress the backpack and increase the pressure helped too). But we were impressed by the convenience of carrying so much water around. We even used it to stay hydrated at a week-long music festival in place of queuing for drinks.

Designed to last, the Klean Kanteen Classic is a popular water bottle choice for those with an active lifestyle. The single wall design makes the bottle particularly lightweight, small and easy to bring anywhere. A powder coat finish also means the bottle is durable and chip-resistant, making it safer for you and the planet.

While the classic design isn't insulated, ice can be added to the 1.75-inch opening by unscrewing the lid. A narrow profile means it fits in most cup holders in cars and on exercise machines and strollers too. There are 10 colors and designs and four sizes in total to choose from. The bottle comes with a sports cap with flow mouthpiece that can be removed for easy cleaning.

Other compatible caps available to buy include a carry loop cap and a bamboo cap. The sports cap can be slightly squeaky when you drink from it, but we tended not to notice this too much. We also never found any issue with the Klean Kanteen spilling in our bag. Plus, it’s dishwasher friendly, which makes cleaning it a breeze! 

The Gym Keg is an ideal water bottle if you like taking on long hikes and want to ensure you'll have enough water to last your journey. This bottle has a volume of just over 74 fluid ounces/ 2.2 liters which does make it relatively heavy to carry when it’s full.

To help with this, the bottle has a built-in handle that is easy to grip even if your hands do get a little sweaty during a strenuous hike or workout. There’s also a carry loop that easily fits around your hand or wrist, or alternatively, we found it worked well attached to a backpack.

During testing, we found this bottle to be fully leak-proof and despite being thrown around in our backpack, the cap stayed firmly on. When we stopped for a water break, we did find you do need to fully stop and take a sip otherwise it’s quite easy to slosh water on yourself due to the large size of the bottle. Because of this, it’s not the best option if you are into trail running or fast hikes and need something to sip while you run. 

Cleaning The Gym Keg is easy and the insulating sleeve can be removed so that you can wash the bottle in warm soapy water. It isn’t suitable for placing in the dishwasher, however. We also found that this bottle makes a whistling sound as you sip from it, which could be frustrating for some. 

How to choose the best water bottles for hiking

Before you invest in one of the best hiking water bottles, it's important to think about how you want to use the bottle and how you'll carry it. But there are several other factors to consider before making your decision, too.

Weight

Whether you're out on a short walk or a long multi-day hike, you don't want to add too much extra weight to your setup. Our guide includes several lightweight options, but your choice may depend on whether you'll carry it by hand or in a bag.

The empty weight is also crucial for larger containers—as they store more water, they'll feel heavier than smaller bottles when filled, so it's handy to reduce the weight of the bottle itself as much as possible.

Materials

If you've been looking for the best water bottle for gym workouts, you'll notice that many of these are made of thin plastics, designed to be thrown around during a workout or place in a cup holder on a machine.

Water bottles for hiking can be more varied as they're likely to end up in a bag, but also because you may want to keep drinks as cool as possible throughout the day. That's why you can find aluminum bottles designed to keep things at your desired temperature for longer.

Features and extras

Although you can find basic water bottles with a screw top and little else, the best water bottles for hiking have useful extras, like insulation sleeves, carry loops, and alternative mouthpieces.

If you're after a single water bottle that can see you through long hikes, local strolls, and a typical workday, these extras can turn your hiking water bottle into something a bit more adaptable and convenient.

We've also included a CamelBak hydration backpack in our guide, which is housed in a lightweight bag with pockets, straps, and netting. If you don't need to take much out with you, then these kind of features and accessories can help keep your pockets clear.

How we test the best water bottles for hiking

Before we recommend any hiking water bottles, we put them to the test to make sure they can withstand regular use. To easily compare between bottles, we use the same testing process for each container.

The first thing we consider is the weight of the empty bottle and materials used. We place water into the bottle and experiment with drinking temperatures after leaving at room temperature and in a fridge, plus the effect it has on the outside of the bottle.

We pay close attention to the mouthpiece, as this determines how easy it is to drink while on the move. But between sips, your bottle needs to be held or stored away, so we consider how easy it is to place in a bag, attach with a clip, or carry on your back.

Because you regularly fill it with water for a variety of sources and your mouth frequently touches the bottle, it's also important to look at how easy it is to clean. Even if it's tricky by hand, we also look at whether the parts are dishwasher-safe.
