Running Hydration Vest Buyer’s Guide

What is a running hydration pack and why wear one?

A running hydration pack (aka running hydration vest) is basically a small backpack for running, and is a great way to carry everything you need on long trail runs, for everything from 10ks and half marathon distances up to ultra marathons.

Most trail runners will own at least one hydration pack as they are the best, and most efficient way to carry essentials including water, energy food, spare clothing (including your running hat when not being worn), mobile phone, keys, and even trekking poles… the list goes on and is only limited to your creativity :).

If you’re relatively new to trail running and you’ve seen other runners with these small backpacks on then you may be curious to know more about them and the pros and cons when it comes to buying your own. You may have also noticed they can be expensive (often much more than $100) so it’s worth doing some research to find the best one for you that will fit well, be comfortable to wear for hours at a time, and store all the water and gear you need to carry when running trails.

While hydration packs have been popular among trail and ultra runners for many years now, they are starting to be more popular among road runners as a comfortable and easy way to carry water while running, as well as other essentials such as your phone and waterproof jacket on longer runs.

What is the difference between a running vest, pack and backpack?

The terms to describe a small running backpack are generally used interchangeably – many people choose to call them running hydration packs (or backpacks) and others call them running hydration vests, or simply running vests. We refer to them in these ways in our content.

Technically, a running hydration vest is a smaller running backpack, whereas a running pack indicates that it has a larger volume, but in reality the description varies by brand and style and you should normally take both terms to mean the same thing – a small pack you wear on your back to carry essentials while trail and ultra running.

We also sometimes refer to them as ‘race vests’ as this is a common terminology used to describe this piece of trail running gear in the UK and Europe, where we lived for many years.

How to choose the best running pack for you

Firstly, and most importantly, having a good-fitting, comfortable running hydration pack is almost as important as having a comfortable pair of shoes on – if it’s uncomfortable then the whole running experience is less enjoyable – nobody wants to run around with an uncomfortable pack that moves around or is difficult to access on-the-go.

This means that when it comes to choosing a running hydration pack, generally most women are going to be better off with a women’s-specific running vest than a men’s version, as these versions have been designed to fit women’s bodies and are more likely to offer a comfortable fit that doesn’t shift around when you run.

Other considerations when choosing a good running hydration pack are its:

Storage capacity and weight

Running hydration packs come in a range of sizes, often measured in litres, with the smallest generally starting at around 4 litres (which is around 1 US gallon, although you can find smaller), and larger packs going up to around 12 litres (3 US gallons) before they start to become larger and more like hiking daypacks. If you are going on a short day hike then a running hydration vest could be a great, lightweight option (for more on what to pack for day hikes, visit our hiking for beginners guide).

Generally, I would not choose to run with a running hydration vest larger than 12 litres in volume, unless I am going fastpacking and need to carry extra food and overnight supplies. For most people, something in between 4 and 12 litres is going to work well, with the most popular options (if you expecting to run for up to 3-4 hours at a time) being between 4 and 6 litres.

That said, if you’re not sure and you expect to be running ultra marathons and trail marathon distances in the forseeable future, then it may be worth investing in a larger volume hydration pack, as the weight differential isn’t that much and good hydration packs feature straps and bungees that allow you to compress them to stop the contents moving around when the pack is half-empty.

Carrying water in a running hydration pack

There are two main options for carrying water with you in a running hydration pack – either in bottles (preferably for most people – soft flasks) or in a hydration bladder.

Depending on the capacity of your hydration vest and how much water you need to take, you could even take both. Most of the hydration vests we have picked come with either soft flask water bottles, or a water bladder, but are so versatile that you could choose an alternative combination if that’s your preference.

Durability and construction

A hydration pack is an investment and something that should be able to stand up to snags, falls, moisture, dirt and more and last for many years. So tough, technical yet breathable material is desirable – and the lighter weight, the better.

It also almost goes without saying that soft fabric with minimal, thoughtfully placed, seams will help reduce discomfort or any potential for chafing during your long runs.

Style and Cost

Style and cost are more matters of personal preference and budget rather than key elements for a running hydration vest’s function, however if you can get a great hydration vest for a good price and which also looks great, then all the better!


Brands offering men’s and women’s hydration packs

Popular brands offering running packs are specialist hydration pack companies such as Nathan, Camelbak and Ultimate Direction, as well as long-term players in the trail running and mountain sports equipment arena such as Salomon. Other brands entering the running hydration pack market more recently include backpack brand Osprey, and larger running brands such as Nike.

Alternatives to running packs

For ultra running there aren’t really any viable alternatives to hydration packs, unless you’re running a very fast ultra and have support crews and places to resupply.

If you need to be self-sufficient on the trails and in the mountains then a hydration vest is the way to go, but for shorter runs consider handheld water bottles and the option of running with a waist belt or fanny pack if you’re not carrying too much gear with you.

  1. Are you aware if anyone sells a hydration vest for running that is sized for an actual man? These always look great but they’re always to small. I’m looking for a 46-48 inch chest hydration vest. I’ve been looking to no avail..

      • Hey lads, I bought the VaporKrar in a X Large and fits a dream. I was 124kg when I first used it. Down to 105 now and the straps are a bit tighter. I’m pretty broad in the shoulders too.

  2. Any pros/cons on Nathan hydration vests? Have never run with one before, but looking to extend to marathon+ distance trail running
