So, you are starting to get your running mileage up a bit. That’s great. But now you have figured out that longer distances require more hydration. Handheld water bottles do a decent job, but sometimes the longest runs require you carry more water than what’s comfortable to hold in your hands.
One solution is the hydration belt. These ingenious inventions can hold water bottles along with other important items like your cell phone or house key. This leaves your arms free while you run.
To figure out which hydration belt best suits your needs, determine how much water and storage space you’ll need to carry while you run. Once you figure that out, then you can pick from our list of 10 best running hydration belts. If you are not sure, the most popular water belts hold 20 oz of water (either one big bottle or two smaller ones) and have enough storage to carry a phone.
But each water belt has unique features from insulated bottles to soft flasks to extra storage for jackets and gels.
Read on to see our top picks and the reasons why we think you’ll love them…
Top 3 Best and Favorites
1. Ultimate Direction Ultra Belt 5.0
This race belt includes two bottles so it would be suitable for longer distance training runs or races. Two 17-ounces soft bottles allow one to carry up to 34 ounces of fluid when running, without feeling weighed down.
If you wish to go for a shorter run, you can leave one bottle at home. Or you may choose to take one bottle of water and one containing a sports drink. The bottles have a PEEVA lining so that there won’t be a chemical taste in the bottles.
The Flex Mono Mesh material is breathable and stable when wearing it. It weighs just 3.4 ounces and the hook-and-loop closure can fit around waists of 26 to 40 inches. The fabric is ripstop for extra durability.
There are four pockets in total on this belt—the two bottle pockets, a large zippered pocket for valuables and a key pocket. The key pocket is a small pocket on the front of the belt, but it may not fit keys with a built-in fob. The three large pockets sit behind you when you have this belt on.
The large zippered pocket in between the two bottle holders is weather-proof and can fit phones up to the size of an iPhone 10. There are also adjustable bungee cords around the pocket that offer extra space for clipping on a key or other items.

2. Nathan Pinnacle Hydration Waist Belt
If minimalism is your style, you may like the Nathan Pinnacle Hydration Waist Belt. It’s a low-profile, effective design that doesn’t take up a lot of space when wearing it. But it offers a lot for its small size.
It has a step-through design rather than a waist clip and is made from stretchy fabric—polyester and spandex. There are a variety of sizes available. If you get the right fit, there should be little to no bounce.
There are four pockets in total on this hydration belt. The water bottle storage pocket is at the back, and features a Velcro flap to keep the bottle in place while you run. This allows for easy access when you’re moving, but the Velcro may wear out quickly.
A 20-ounce soft bottle with a locking cap is included. There are light compression tabs around the hydration pockat, which help to keep the bottle secure as it gets smaller the more water you drink.
A large front zippered pocket can carry most phones. Two side slip-in pockets are ideal for small items like electrolyte tablets or energy sweets.

The 18oz Ergological™ SpeedDraw Flask has a Blast Valve cap which gives you small bursts of liquid at a time. It’s BPA-free so it’s safe to drink from and shouldn’t have any chemical smell or taste.
There is a large, expandable triangular-shaped pocket which can hold a phone or nutrition items. This is the only pocket, but there’s also a compression cord system which can be used to hold a light jacket.
Some may find that the bottle bounces too much when it’s at the back. Some have found that wearing the bottle holder section on the hip reduces bounce but the bottle gets in the way of their arm swing.
- Expandable zippered pocket
- BPA-free 18 oz flask
- Insulated and angled bottle pouch
- Bounce-free design
- The bottle may bounce too much at the back, but wearing it on the hip means you may hit it with your arm when running

Hydration Running Belt Buyer’s Guide
If you are shopping for a hydration running belt, you’ll quickly realize that the size and scope of the options are quite vast. Hydration belts – also called waist packs – carry various amounts of water from a lot to a little. They come with at least one but sometimes two or more bottles in different shapes and styles. And they have extra storage for bringing along extra gear on your run.
We’ll review what factors to consider when shopping for a running hydration belt. Depending on where you run, what you are training for, and how far you go, the type of waist pack you should buy will vary.
Hard Bottle vs Soft Flask
In the past, running hydration belts only came with hard water bottles. These were similar in size and shape to what you might buy for a bike or a stand-alone handheld bottle. And even today these types of bottles are still available and popular.
Some are still tall and round in shape, holding 16-24 oz of fluid. But more often they are flat and rectangular with a 10-20 oz capacity. This shape allows them to sit better around the waist while still carrying roughly the same amount of liquid.
A few years ago, new waist packs came out with soft flask water bottles. These look and feel like a bladder or reservoir that you find in a hydration pack, but smaller with a valve to drink from.
Soft flasks sit nicely around your waist. They are generally more comfortable to wear. There is less sloshing when you run, especially as you drink more from the bottles. They also collapse down when they are empty, unlike hard bottles. To drink, you bite down on the valve and squeeze fluids into your mouth.
But there are two distinct disadvantages to soft flasks.
The first is cost. Packs with soft flasks are more expensive. Sometimes as much as 25-40% more than a similar pack with hard bottles. If you are training for a one-time half or full marathon and don’t anticipate using your pack often, it may be more economical to buy a pack with hard bottles.
The second is that soft flasks tend to hold less fluid than hard bottles. If you want to take along the most water, you’ll be able to hold a few more ounces in a pack than with hard bottles.
Insulated vs Non-insulated Bottles
Another factor to consider with bottles is whether they are insulated or not. This mainly applies to hard bottles as the soft flasks only come in one (non-insulated) option.
Insulated bottles cost a little more; however, they’ll keep water and other fluids colder in the summer and help to prevent them from freezing in the winter. Otherwise, they basically look and hold the same amount of fluids as non-insulated bottles.
The hydration belts themselves are also different. They come with insulated pouches to hold the bottles, adding another layer of insulation to the bottle and pack.
In the summer, we like to throw the bottles in the freezer a few hours before a run. Take them out, add some ice, and your water stays nice and cool even on the hottest days.
Bottle Valves: Pull vs Bite vs Jet
Bottles come with three types of valves to drink from. They all do their job, that is to get fluids from the bottle to your mouth. But how they do it varies and you may have a preference for one over another.
A pull valve is your classic water bottle. Pull the top and the water flow opens so you can drink. Push it down and it stops.
The pros are that these are simple and easy to use. The con is that if you forget to push the valve closed, water leaks out the top onto your waist pack and/or clothing.
Bite valves always remain closed. Until you bite down on the soft, rubber valve while simultaneously squeezing the bottle. Unlike the pull valve, these won’t leak. But they can take getting used to if you’ve never tried them before. Some people don’t like having to bite down while you drink.
Amphipod offers another style of valve called a jet valve. Like the bite valve, this won’t leak while you run. There is nothing to push or pull. But to drink water, you have to squeeze the bottle fairly hard until a strong blast of water squirts out. Some people have complained the water comes out too fast and shoots down their throat!
Size and Number of Bottles: Capacity vs Weight
Waist packs usually come with one or two bottles. FuelBelt does make some versions that come with 4-6 small bottles.
The number of bottles you need will come down to how much fluid you want to carry as well as whether you want to bring two different types of hydration (like water and energy drink).
If you only need to carry water and don’t plan on doing runs in hot weather or going out for long runs, a small, single bottle should be sufficient.
But for longer runs, or if you like to take two types of fluids, then two bottles are the way to go.
FuelBelt’s 4-6 bottle packs are designed to evenly distribute a large quantity of water. Space the bottles evenly all around the waist pack and you should experience a smoother, less bouncy pack. This sounds good in theory but it also means you need to clean, manage, and keep track of extra bottles.
One other consideration is that the more water you carry (like in waist packs with two large bottles), the heavier your load will be. If you like to stay light and nimble, you probably won’t want this much water.
Besides carrying fluid, waist packs often have extra storage compartments to stash other gear. Some only have room for a few gels or keys. But other packs can hold a phone, headlamp – even a jacket strapped on with elastic cords.
If you plan on bringing a lot of extra gear with you, look for a pack with added storage space.
