The Best Running Hydration Belts in 2021


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…

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.

Extra Storage

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.
