Osprey is well known for its top-quality packs for hauling items on any occasion. This is a fact that is highlighted by the 5-star rating received by most of their Osprey Raptor 14 MTB Hydration pack. You'll never go wrong by selecting the Raptor 14 as it is well packed with features. 

The Osprey Raptor features an impressive 14 liters of storage capacity and comes with a 2.5-liter water reservoir. With such a large internal capacity, you'll be able to carry all the items and water you need. Furthermore, this pack doesn't lack comfort in any way.

It has a contouring AirScape back panel and straps that are bike-specific, so they don't get in the way while holding the handlebars. And the added sternum strap ensures that the bag doesn't shift around even during fast-paced cycling. The Osprey Raptor 14 also includes a lightweight sternum strap magnet that allows you to sip water quickly.

The most impressive thing about this mtb pack is the additional features included: a removable roll-up tool pouch, a scratch-free slash pocket, hip belt pockets, and the LidLock helmet attachment. It also has a pre-arranged main compartment that will allow you to organize your bike tools.

The Thule Vital is another excellent option that is well suited for mountain biking. It has a smaller overall space with just an 8-liter capacity, but that makes it a lightweight pack that you'll surely find less bulky to schlep around. The good thing is that it still has a 2.5 L reservoir inside the bag. 

Paired with their hydration pack is the Thule ReTrack hydration hose that is easy to access and has a magnetic design, so it stays in place on the strap. Moreover, there are still many external and internal features to love with the Thule Vital. 

Internally, you get an organized interior neatly separated to store keys, cords, bike tools, and other gear. Externally is where the bag shines; it has jersey style side pockets to store items like snacks quickly. Plus, it has an expandable 8L cargo storage that will allow you to add more space to haul items.

The Seral Lumbar is another highly rated pack from Osprey. However, this is a pure lumbar mountain biking hydration pack for when you don't need to carry lots of items in a bag. For quick mountain biking adventures, this pack is more than enough to store water and a small number of items.

Inside this lumbar pack, you'll find a small space that is well organized to carry some tools and other essential gear. It also houses a 1.5L reservoir paired with a magnetic bite valve that you can access when you want a sip of water. Moreover, you still get hip belt pockets on either side that will allow you to store snacks and other on the go essentials. 

The back of this lumbar mtb hydration pack also features Osprey's highly loved padded back panel that offers superior comfort and ventilation. And the ErgoPull waist strap makes it very easy to adjust in order to achieve a snug fit. We also really liked that there is a blinker light attachment on the back of the pack so you can improve your visibility in the dark.

The Water Buffalo mtb hydration pack is the top choice for mountain bikers on a budget. This bag is extremely affordable and has all the features needed to make it an option well worth considering. It comes with a 2L hydration bladder that is good to keep water cool for up to 5 hours.

While it is mostly a pack to house a water bladder, it does offer a fair bit of storage space in the main compartment. We found it just large enough to hold items such as a hand pump, sunglasses, a fair bit of snacks, and a smartphone. Besides, it has a lightweight design with breathable straps and a high-quality bite valve that you clip onto the shoulder straps for easy access.

If you don't want to spend a lot, this mountain biking pack is the only option we'd recommend.  

Buyer's Guide - How to choose a MTB hydration pack?

Best Road Bike Helmet Under 100

Before you go ahead with buying best hydration packs, here are a few things you need to consider:

Water Capacity

While hydration bags offer the ability to carry more than just water, it's top function is to haul water conveniently. As such, water capacity was something we heavily considered before ranking a pack as one of the best. With that said, you need to know that not all mountain bike hydration packs come with a water bladder. In most cases, they will only offer the compatibility to add a water bladder to the bag. 

So before you go ahead and buy a pack, you must first know whether a water bladder is included or if you'll need to buy one. The next thing to keep in mind with the water capacity is that hauling water means added weight. For each liter of water capacity, it is equal to about 2.2lbs of weight. So before setting out, you should consider how much water you will consume and only take what is necessary.

The best hydration packs we've listed all have a water capacity over 2 liters.

Gear Capacity

MTB hydration packs aren't only for carrying water. They allow you to carry quite a few pieces of biking gear in the single backpack. This ability to haul gear and a water bladder make this backpack style one of the most versatile bike accessories to own. With a good backpack, you'll get the ability to load up on all your essentials. From tools and spare items for your bike to things such as your helmet, a blanket, and, most importantly, food! 

It would be best if you always went for options with at least 4-5 liters of space to store all your gear and other essentials. 


The features are another very important aspect of the best mountain biking hydration pack. The best hydration pack features include more than just the water and gear capacity, but also other things like waterproofing, breathability, adjustability, and everything related to the hydration bladder. 

A mountain biking hydration pack must provide a good water bladder with a good bite valve that allows water to flow freely. Moreover, it should also be easy to be inserted or removed for refilling. 

The best mtb hydration pack should also come with multiple compartments so that you can organize your gear, snacks, and other items neatly in the bag. We've already made sure that the bags we list as the best hydration packs for mountain biking have all these key features and more. 

Fit and Comfort

The last thing to consider is how well the pack fits you as the rider. While the mountain biking hydration backpacks we've reviewed fit us well and offer a universal fit, some packs are better fitting than others. Moreover, some persons might prefer a pack with plenty of strap adjustability. While for others, it might not matter so much. But keep in mind that bags with a fit tighter, especially those with a torso strap, are much safer to wear.


Mountain Bike Backpack

What are the best mtb hydration packs on the market?

The CamelBak M.U.L.E and Osprey Raptor 14 are both highly recommended hydration packs for mountain biking. They offer a great balance of size, storage, and comfort for mountain biking adventures.

How do the shoulder straps on mountain biking backpacks impact comfort during rides?

Shoulder straps on mountain biking backpacks play an important role in determining the comfort level of the pack during rides. Well-designed straps should be adjustable and contoured to fit the rider's body, ensuring that the pack stays in place and doesn't shift around during fast-paced cycling.

Are there any hip packs specifically designed for mountain biking?

Yes, there are hip packs specifically designed for mountain biking. These packs typically feature a hydration reservoir or hydration bladder and may have additional zippered pockets for storage. They are designed to be worn around the waist and provide a more compact option for carrying water and essentials while on the trail.

How do compression straps on a mountain biking backpack affect the pack's stability?

Compression straps on a mountain biking backpack help to stabilize the load within the pack and prevent it from shifting around during rides. They also help to reduce the overall volume of the pack, making it more compact and easier to carry.

What are the benefits of a chest strap on a mountain bike backpack?

A chest strap on a mountain bike backpack helps to distribute the load of the pack across the chest and shoulders rather than just the shoulders. This can help to alleviate shoulder strain and improve stability during rides.

Are there other packs besides shoulder and hip packs suitable for mountain biking?

Yes, there are other packs suitable for mountain biking such as larger hydration packs, bum bags and hydration vests. These packs are designed to be worn on the back and offer more storage capacity than shoulder or hip packs.

Can a rain cover be added to a mountain bike backpack?

Yes, a rain cover can be added to a mountain bike backpack to protect the pack and its contents from rain and moisture. Many packs come with a rain cover included, or they can be purchased separately.

How do hydration systems in mountain bike backpacks compare to carrying a water bottle?

Hydration systems in mountain bike backpacks offer the convenience of hands-free hydration and typically have a larger capacity than a single water bottle. They also have a tube with a bite valve, making it easy to drink while riding. Carrying a water bottle may be more convenient for shorter rides or when carrying multiple bottles is an option.

What are some key features to look for in a mountain bike pack for organization?

When looking for a mountain bike pack for organization, look for packs with multiple pockets and compartments, such as organizer pockets and zippered compartments. Additionally, look for packs with mesh pockets and a stash pocket for easy access to smaller items.

Are there specific hydration packs for enduro and gravel cycling?

Yes, there are specific hydration packs for enduro and gravel cycling. The Camelbak Chase vest is a popular enduro hydration pack, and the Osprey Seral Lumbar Hydration Backpack is a great option for gravel cycling. It is important to look for packs with adjustable straps, chest strap and waist belt to ensure the pack stays in place during intense rides.
