The best running water bottles 2024: convenient hydration for mid-length runs

Taking a minimalist approach to a moderately long run? Then you'll need one (or two) of the best running water bottles. Staying hydrated is obviously crucial on a run but there's definitely a balance to be struck. Carrying a hydration pack can be overkill for many adventures, but carrying nothing is a recipe for poor performance and dehydration.

That's why the best running water bottles are designed to be ergonomic, lightweight and easy to sup from while on the move. On race day, they're easily refillable and are certainly preferable to single-use plastic, which is thankfully being phased out across the running world.

Better still, these excellent bottles can be used for other outdoor pursuits too. We love the packability of soft flasks, which pack down to nothing and can often be paired with a hydration pack for more adventurous runs and speed hikes. 

We've tested all the bottles in our selection on the roads and in the backcountry to bring you this guide. Our pick of the best running water bottles is the fully-featured CamelBak Quick Grip Chill Insulated Handheld, though all the products in this guide will make for a great addition to your running adventures.

This is the quick list, a snapshot of the best running water bottles available in 2024. To delve deeper into the features and qualities of each featured bottle, see our more detailed reviews further down the page in this guide.

The best running water bottles 2024

The best running water bottle overall

CamelBak have `'packed a lot of incredible features into their Quick Grip Chill Insulated Handheld with 620ml Podium Chill Bottle` according to our trail expert. 

The first is the high-quality, BPA-free insulated bottle which keeps water cold for twice as long, tasting less plasticky and with a wide opening that made it easy for us to add electrolyte powder or refill from streams. There’s an easy-to-use on / off valve so you don’t lose any liquid, and if you squeeze the bottle it propels a jet of cool water down your throat so you don’t have to make any sucking effort when you’re already tired – a nice touch. 

There are two pockets: the zipped one is large enough for a standard (not plus-sized) smartphone, cards and a key, while the elasticated one will take a snack. It would be good to see a key clip for extra security and perhaps less chance of the key bouncing up and down next to your phone. We found that carrying the bottle was effortless thanks to the easily adjusted hand grip with reflective details for safety. However, if it’s full you will still feel a bit heavy on one side, such is the nature of handheld bottles.

The best running water bottle for value

The Kalenji Running Hand Flask is a light and easy way to carry 350ml water on short runs. The bottle has grooves to enhance the grip, and we found the opening was wide enough to easily pour in any electrolyte or energy drink powders, and fill up quickly from streams. The one-way valve allows you to squeeze water out of the bottle into your mouth for easy drinking on the move, but there isn’t a complete closure so make sure you don’t place anything heavy on it while travelling as the pressure may cause the valve to open. 

The holster adjustment is very easy to tighten around any sized hand and can be used easily in the left or the right thanks to its asymmetrical design with a large hole for the thumb. There’s no pocket but the Kalenji tag is reflective, which is a nice touch for night running. There is some sloshing from the hard plastic bottle but, according to our tester: "for this price, you can probably put up with that."

The best value water bottle with storage

Carrying the Ultimate Performance Kielder Handheld Bottle is made easier with the adjustable, padded, reflective strap over the back of the hand so you we didn't actively have to grip the 600ml bottle. 

There’s also a small zipped pocket with a key clip, big enough for car keys, a cash card and a small snack but not a smartphone (although it would fit a small Nokia-style emergency phone). The bottle is BPA-free and has a wide opening so we found it very easy to refill in streams or pour in electrolyte powder. We foudn that the rubberized drink valve was also very easy to use and doesn’t leak. 

"If you fill the bottle and stuff the pocket to full capacity it can feel a little heavy in the one hand" according to our running expert. Alos, once you’ve drunk some of the water, it sloshes around with each step. However, if you don’t want to use a running backpack or waistbelt this is a really good, great-value option, available in five bright colors, for carrying quite a few essential items on your run.

The best running soft flask

The Salomon Active Handheld Running Bottle is a super-light and simple way to carry 500ml water on short runs. The soft bottle compresses down as you drink so you don’t have the slosh of water to disturb your run, and the very simple adjustable strap threads through a loop at the base of the bottle then Velcros tight to lock your hand around it so you don’t have to grip tightly. On test, we found that it works well, but this system means we were only able use these specific Salomon bottles with the loop at the base with this holster. 

We found the opening to the soft bottle was wide enough to easily pour in any electrolyte or energy drink powders, and fill up quickly from streams. A lock to the valve minimizes spillage. There is no pocket as this is a truly lightweight, minimal piece of kit for runs where you just want to take water, or longer runs where you need a lightweight solution to carry extra water in your hand as well as your running pack. 

There’s a little reflective strip on the tag at the base which is a nice touch for night running. Retailing at a reasonable price, "this a great lightweight option for carrying water on your next training run," according to our trail running expert.

The best soft flask for pack compatibility

The Osprey Duro Dyna Handheld Bottle is a light and easy way to carry 360ml of water and a key or small snack on short runs. On test, we found the bottle is soft, so as we drank it collapses down, which prevents the sloshing that you get with the harder plastic bottles. The opening is wide so it’s easy to pour in energy or electrolyte drinks in and fill up from streams. 

The fit around the hand is great with a very lightweight holster that you can adjust around the wrist so you don’t have to grip the bottle at all. It suits a right-handed fit better, but you can still wear on the left if needed. It's also comptatible with Osprey's Duro and Dyna hydration packs, slotting into the shoulder straps for easy drinking on the move. The small, stretchy zip pocket is great for a small snack, keys and cards (not a smartphone), and the safety whistle zip pull is a really nice touch. The pocket area is stiffened so you can operate the zip one-handed with ease. 

The second elasticated gel pocket confuses us, however, as it appears to be upside down with the opening at the base of the bottle… We can’t work out if we’re missing something here – when we run with the opening facing downwards we’re worried about the gel slipping out. 

It’s a high price but our tester says that "apart from the confusing elasticated pocket, it’s one of the best."

The best running water bottle for small hands

The Ultimate Direction Fastdraw 500 Running Bottle is "one of the comfiest plastic bottle designs to carry" according to our expert tester. This is because it’s slim and wide rather than a regular round water bottle. 

We found that this is especially good for people with smaller hands, and the adjustable strap fits around tightly so you don’t have to actively grip the bottle to carry it. The bottle opening is neither narrow nor particularly wide so it shouldn’t be too hard to pour any energy / electrolyte powders down its neck.

Ultimate Direction have had a great idea in making the single-zipped pocket transparent so you can see and use your phone without taking it out. However, it would be better if they sold standard and plus-size versions of the Fastdraw 500 because a standard-sized smartphone shifts around in the plus-sized smartphone (iPhone X) pocket with each step. It would also be good if there was a separate compartment with a clip for keys, as they're free to clang and bang around on your phone in there – screen protector needed.

The best basic bottle for short runs

If you want simplicity, the Ultimate Performance Runners Bottle is a great value, BPA-free handheld water bottle for every runner. 

The simple, donut (mmm donuts…) design is very easy to carry with one hand through the middle, gripping onto the curved finger-grooves. The bright colors (blue and pink) will appeal to a lot of runners, as will the transparent mouthpiece protector for extra hygiene should you drop it. 

On test, we found it was easy to swap hands too, or pass to another runner or support crewmember. It’s fairly slim and the neck of the bottle is narrow, which makes it easy to pack into a suitcase or backpack for travel. "However, this can mean that it’s a little harder to pour electrolyte / energy powder into" according to our trail expert. This also means it's slower to fill up at streams. 

If you don’t mind the soft sloshing with every footstep the only downside to such a simple bottle is that you do have to grip it at all times – some of the others in this test have fabric loops around the hand that allow you to run without such a tight grip, or any grip at all.

The best running water bottle for no sloshing

We thought that the Ultimate Direction Clutch 5.0 running bottle was so promising with its lightweight pouch and soft bottle inside. However, we just weren't able to get it tight enough to release our active grip on the whole caboodle like we could with the others here, especially if the bottle isn’t full. 

This is quite disappointing as the multi-way strap looks so promising; it allows you to use it either with a thumb through the middle of the strap or the thumb round the bottle, but it just won’t go tight enough on either large male or smaller female hands (we tried a selection!). 

However, if you don’t mind gripping onto the Clutch for the entire run, it works well. "The soft bottle itself is great" according to our expert tester, with a wide, chunky opening that’s easy to undo, plus an in-out / on-off bite valve. 

As it’s soft, the bottle also compresses as you drink the water so there is no room for sloshing – awesome! The stretchy, zip pocket with key clip is also fantastic for small snacks, keys and a card.

How we test the best running water bottles

Each of these running bottles was extensively tested on trails, paths and pavements, across a range of different distances and in various climatic conditions, so we could see how sweaty our hands felt after a few miles, and assess their overall ergonomic performance.

How to choose the best running water bottle

For a seemingly simple piece of kit, there are quite few factors and features to consider and look out for when you’re trying to find the best water bottle for running to suit your needs. Before you make a choice, think about where and when you’re most likely to use your running water bottle, and contemplate the following points… 

Grip

The main thing is that you don’t have to actively grip the bottle, otherwise you’d just carry a bottle! So check that you can get the adjustment tight enough, release your grip on the bottle and swing your arm to check how well it is attached to your hand.

Bottle design

There are two types: hard and soft. We prefer soft as they compress down as you drink, avoiding annoying sloshing as you run. Just check the holster still adjusts around your hand enough when the bottle has reduced in size or is empty. 

Valve

An on / off valve to the bottle is a great feature to avoid leakage.

Capacity

We don’t recommend carrying much more than 350ml to 500ml in one hand as it can make you feel a little lopsided, especially if you have a pocket in the holster with snacks, keys and even your phone in as well.

For really long runs and events like mountain marathons, you may want to consider the large capacity of a hydration bladder.

Holster

Depending on how much you wish to carry with you, you can get a very simple, light holster that just attaches the bottle to your hand, or one with one or two pockets. Look for a zip on these so nothing falls out. A key clip is handy too.

Reflective detail

If you’re running in the dark a reflective strip or logo is a great feature.
