Best Hydration Packs For Mountain Biking (2021)

If you are new to mountain biking, you would prefer to ride bag-free on the trails with no weight on your back and no responsibility to keep the bag stocked during every ride. However, mountain biking is not an easy sport, and more often than not, you end up wanting spares for your gears or extra layers on long rides. Not only that, you will definitely need food and water along the ride.

So, what is the solution for a fully equipped mountain bike ride? A hydration pack! A hydration pack is a necessary evil that carries all your essential supplies like food, water, tools, spares, layers, and gadgets on a mountain bike ride.

Hydration packs can vary in shapes and sizes depending upon their purpose. If you plan to go for a full day or two rides, you need a large backpack with enough room to fit a toolbox and other essentials. If you are on one of the casual rides, you need a low-profile backpack or hip pack.

In this article, we discuss the best hydration packs for mountain biking based on various metrics.

With a 2.5-liter liquid capacity, CamelBak Classic does not have much storage to offer, but then again, if your concern is capacity, then this is not the pack for you. An ergonomic handle for easy refilling, the Crux hydration bladder with a Big Bite valve system delivers 20% more water per sip. Unlike other packs, it does not have the quick-release feature nor is it easy to clean.

Key Considerations For Mountain Biking Hydration Packs

Water-Carrying Capacity

The main purpose of buying a hydration pack is to carry enough water for the strenuous sport of mountain biking. Whether you are going on a short ride or planning a full day of mountain biking, having adequate water by your side is essential to keep you from drying out on the trail.

The amount of water you will need depends on how long you plan to be on the road, the temperature, and whether there are pit stops along the way. The minimum water-carrying capacity your hydration pack should have is 1.5 liters per hour.

Most of the hydration packs feature 2 or 3-liter reservoirs, enough for most riding adventures. For a full-day ride, you need at least a 3-liter reservoir to make it through the day.

Gear Capacity

Contrary to the name, hydration packs are not just for carrying water reservoirs but also for other gear. When going on a ride, you should at least carry layers, snacks, rain gear, a full-face helmet, pads, and a toolbox.

Other compartments can feature essential items such as a tube, a pump, tire levers, a quick link, and a first-aid kit. The load you carry can differ from person to person, but usually, it lies somewhere between 7-liters and 20-liters.


While most of the hydration packs are one-size-fits-all, the adjustments from person to person are important to ensure comfort during the ride. It is best to consider your torso length and waist size and even try on the backpacks to play with the adjustability before taking them on a ride.

Poorly fitting hydration packs can result in sore shoulders or back. Look for a hydration pack with a sternum strap and a hip belt to stabilize the load and distribute the weight off the shoulders.


Let’s face the facts; you are bound to sweat a lot on a mountain bike ride despite donning the most breathable gear in the market. Over-the-shoulder hydration packs can make your back extremely sweaty and clammy during the ride.

It is crucial to get a pack with a breathable back panel, leaving some gap between the body and the bag to allow adequate airflow. Ideally, you should opt for a pack that has a suspended mesh back panel.

Bladder Bite Valve

Hydration bladders vary in shapes and sizes, ranging from 1.5 liters to 3.0 liter with a circular screw opening or a dry-bag-style fold-over closure at the top. A bigger opening usually has more advantages since it allows easier refilling, removing, cleaning, and drying options.


Since a hydration pack contains all kinds of stuff, from tools to snacks to the first-aid kit, it is important to keep these items organized in separate compartments, so you don’t have to take everything out when looking for a single thing.

Appropriately sized compartments prevent items from rolling around into one another and everything congregating at the bottom of the bag. The organization goes a long way when you need something urgently. Individual compartments and layouts are essential.

Price Range

While it is important to invest in a fully-featured hydration pack that meets all your needs and wants, we know that not everyone is looking to pay top dollar for a backpack.

Most people are looking for good performance at a reasonable price, and the rest want everything perfect no matter what the cost. Hydration packs include both the bladder and the backpack, which cuts the cost significantly and provides both the purposes in one item.

One of the cheapest models you can find is the CamelBak Classic, a great performer in all aspects and offers a minimalist design at a low price. On the other hand, models like Gregory Endo 15 with superior capacity and all-rounder like Osprey Syncro 12 can cost a lot more.


Mountain biking is a demanding sport that can prove to be brutal to your body. Hence, you must keep your body hydrated and replenish energy every chance you get during the ride. Hydration packs cover all your storage and hydration needs during mountain bike rides. These backpacks can be your essential companion, and it is wise to keep one along for the ride.

While you will find several different kinds of hydration features, each with its own attractive feature and selling point, you should keep your specific need for the pack in your mind. Do you need a pack for long rides or short ones? There are many options in the market that will leave you dazzled, and focusing on your needs is the key to a wise decision. Plan your rides and get a hydration pack accordingly.

Remember to research well, invest wisely, and stay hydrated during one of these strenuous mountain biking rides.
