Best Mountain Bike Backpacks (2021)

Mountain biking is a strenuous sport that requires careful planning and a great deal of stamina. Before going on one of your adventures, it is important to keep your carry-ons in check so that you have no unprecedented troubles in the wild. If there is one thing you always carry with you on a ride, it is water. Hence, water capacity is important to consider in a backpack.

The best mountain bike backpack must have a hydration reservoir for a water bladder. In addition to water reservoirs, it is great to have backpacks that can harbor extra gear in the space. A good mountain bike backpack allows airflow between your back panel and shirt and provides good breathability.

The e-bike battery sleeve ensures a secure and safe ride on the trail for all-day adventures. It is compatible with helmets and allows you to carry them around safely by stowing and securing your backpack.

Key Considerations For Buying a Mountain Bike Backpack

If you just read the review, you will need a set of factors to navigate through the guideline for mountain bike backpacks. Here are some of the factors you need to consider before you invest in your MTB backpack with brief explanations of why they are important:

Size and Shape

Most MTB backpacks are smaller than traditional backpacks and significantly thinner, or with a significantly reduced profile.
Why it Matters: Here’s the thing about mountain biking: it’s all about speed. That means that there is no part of you or the bike that is not battling against wind drag, not to mention the occasional errant branch that is out to pull you from the seat of your bike. So the overall size of the pack is going to make a big difference in how the bike is controlling.

Water Capacity

If there is one thing you absolutely need on a mountain bike ride, it is tons of water. Most full-sized mountain bike backpacks entail a 3L bladder but most of even the best backpacks that Osprey offers include 2.5L water reservoirs. In terms of water capacity, consider your own specific needs such as how long you are going to be riding and how much fluid you will actually need on the trip.

Storage Capacity

The first thing you need to think about is how much gear you take with you on the average ride. Think about extra layers, tools, snacks, extra tires, etc. MTB Backpacks range in internal storage capacity, with the smaller models coming in around 9 LITERS and the largest models pushing 30 LITERS and above.

Why it Matters: The amount of storage capacity you need is dependent on how much you need to carry, so it’s essential to figure it out beforehand. Ask yourself: am I going to need room to store other gear, such as pads and armor?

If you only go on short rides, then you probably only take a few tools whereas all-day rides in the mountains require that you take more with you. If you like bike-packing then you need even more space for food and camping equipment.

Magnetic Hose

Carrying a hydration pack that lacks a magnetic clip to keep the hose in place can be extremely frustrating. The non-magnetic hose often flaps around and gets in the way while you are on the trail. There is seldom you can do about it on the way.

When shopping for a new mountain bike backpack, make sure it has a little magnetic clip or some other clip system on both the hydration hose and the chest strap so that you can avoid struggling with a wayward tube. Most of the packs above come with a magnetic hose system, such as the Dakine Syncline 16L, while others come with a simple clip system.

Helmet Compatibility

Some backpacks utilize a specialized pocket that you can stick the helmet into. Other packs, like those made by OSPREY, take it a step further with a LidLock system that is simply a well-placed bungee strap. Find a pack that can stash your helmet and you’ll be good as gold.


When you’re looking for your Dynaplug, CO2 inflator head, or a first aid kit, there is seldom anything worse than having to dump the contents of your bag out on the trailside because you couldn’t find your desired items.

Several mountain bike backpacks have zippered organizational pockets and compartments or dedicated sleeves for keeping specific tools. Others may have additional features such as removable tool rolls. However, the downside of dividers comes with a small cost on capacity. When it comes to organization, no one beats the Camelbak H.A.W.G Pro 2.0.


A mountain bike backpack can prevent you from radiating as much heat away from your body as you ride which will make you feel hotter than intended. When shopping for a pack, look for one that has a suspended mesh back panel, or at the very least channels for airflow and an air-permeable material.

Price Range

One of the most important things to consider before investing in a mountain bike backpack is your budget. While the most expensive backpacks generally offer the best features, they can also be too costly for most people. For example, the Osprey Raptor 14L or Camelbak H.A.W.G Pro 20 can cost a fortune but if you are on a tight budget, Dakine Syncline 16L is the one for you.


When it comes to mountain bike backpacks, it is important to consider all the factors before you invest in a single backpack that fits all your needs. Among the plethora of options, you can pick one that meets your priorities such as organizational features, ventilation, storage space, greater water capacity, and bonus features such as magnetic clip system or helmet compatibility. Remember to stay organized, hydrated, and safe during your mountain biking adventures!
