Whether you’re trail-racing, running a marathon, a casual runner or training for your next event, after your shoes a hydration pack for running should be the most essential piece of equipment on your list. We’ve compiled reviews, a guide and answered some FAQs to help you find the best hydration packs for running.

Since aid stations are spaced far apart, a hydration pack ensures runners have enough hydration to make it to the next station.  Some hydration packs in our review have bladders or reservoirs, which are soft, flexible plastic bags that sit on your back. Others have pockets for soft flasks of water that rest in the front pockets. We’ll go over the differences in our buying guide towards the end. For now, let’s get started with our review of the best hydration packs for running.

What to Look for in Hydration Packs for Running 

Like all products, not all hydration packs are created equal. The main difference is how the bag stores water, either with soft water bottles or a flexible plastic bladder. Other things to consider are the overall fit, ease of access to the water supply, and the gear storage capacity. 



Hydration backpacks are a lot like day-hike backpacks but with running features. They have a simple hip belt, low profile, and an abundance of pockets. Often, hydration packs will offer the user more storage than vests. 


Hydration vests fit snug to the body. They secure around your body like to a backpack, but the profile is lower. They also usually have more pockets on the front of the shoulder straps and a secure hip belt. There is often storage for water bottles on the front pockets. 


As the name suggests, hydration belts encircle the hips, as a belt would. The cargo space is often smaller than you’d have in a pack or vest. For this reason, they’re a fantastic option for light and fast adventures like a trail run or hike. If you don’t want the hindrance of a pack or vest, a belt is a perfect substitute for staying hydrated. 


As we’ve suggested, hydration packs usually have two different types of water storage: flasks in the front pockets or a reservoir pack in the back. Most bags that are designed for storing containers in the front have less storage space behind. 

Take a mental inventory of the essential gear you’ll need on runs. Now, ask yourself how much space you need to fit a jacket, food, and anything else for your comfort. Then, choose an accommodating pack, whether that’s 2 litres or 7 litres of storage. 


The volume of water the hydration pack holds is arguably the most crucial factor when deciding on a product. Most packs accommodate both types of hydration flasks (bottle or bladder), but they will only come with one of the two. You’ll have to purchase the one not included separately. 

All in all, it’s essential to think about the types of runs you’ll be doing. Are you going to go on all-day trail runs with few refilling stations? Are you going to be on the road where water is widely available? Water is heavy (1 litre weighs 32 ounces), so think carefully about how much you need. 


Again, it’s wise to mull over the types of running you’ll be doing. If you don’t want to be weighed down by a chunkier pack, choose a lightweight model. If you have a lot of gear to carry and don’t mind the weight, you’ll be safe with a heavier one that secures against bouncing too much.

FAQs for Best Hydration Packs for Running

Are hydration packs really worth it?

A hydration pack eliminates the need for bulky water bottles and costly (financially and environmentally) plastic ones every time you run. Though hydration packs require an initial investment, you’ll save considerable plastic and cash in the long-run.

After experiencing the incredible convenience of a water pack, you may feel that you’ve needed one for a long time. 

How much water should I bring?

For lightweight activities like running or walking, 0.5 to 1 litres should suffice. For short-distance bikers, hikers or runners, go for 1 to 1.5 litres. If you’ll be doing moderate to long runs and want minimal refilling, 2 to 2.5 litres is ideal. Lastly, for ultra-runners and explorers, go for 3 litres or more so no refilling is required. 

How to clean the hydration pack tube

It’s best to detach the tube from the reservoir before cleaning it. I have one and can recommend cleaning it after each use, or mould will start to build up. Combine hot water and two tablespoons of baking powder or bleach. Let the mixture sit for about 30 minutes. Then, run it through the tube, releasing it at the bite valve. 


After reading this extensive guide on best hydration packs for running, we hope that you have a better idea of their features and differences. A hydration pack adds convenience and safety to your runs for years to come. 

Due to the different nature of running and the wide array of personal preferences, we’ll refrain from recommending just one pack—there is a pack to suit everyone’s needs. Please browse the broad range of water packs on Altitude Sports to find the best fit for you!
