Best Hydration Pack for Mountain Biking

Using A Hydration Pack For MTB 

A few years back, there was a huge trend amongst all outdoors extreme athletes, whether that be trail runners, mountain bikers, or hikers of having a hydration pack. 

For some reason, this trend fizzled out with time, and the trusty old water bottle made a comeback. Which; of-course is fine, that is if it fits the needs of the rider, which for some riders it will.

However, the hydration pack cannot be overlooked as an essential tool for mountain biking, especially given it’s ultra-portable and convenient size, ease-of-use and suitability to the sport. 

Some riders simply sweat like cows in a slaughterhouse, and need convenient hydration on the go, without stopping and rummaging in a backpack or carrying unnecessary weight.

Best Hydration Pack For Mountain Biking

Hydration Pack VS Water Bottle

While it is probably safe to say that none of us would ideally want anything besides the fresh air wind rushing through our helmets, the reality is that some things are mandatory and just cannot be left behind on a ride. 

Things like food, water, layers, spares and tools you’re likely to need on a ride. Hydration packs serve as your best bet for MTB, because not only is the hydration system super easy to use on the go and can fit all your supplies, but it is built in instead of having an unwieldy water bottle uncomfortably bashing against your back. 

With the advent of smaller, lighter frames, on many bike models there is just simply no space for a water bottle to fit in a holder anymore. 

Now, water bottles are definitely suitable for beginner riders, but if you plan on hours of uninterrupted riding, then we’d highly recommend you look into one of our best hydration packs for mountain biking.

Osprey Raven 10 Women’s Bike Hydration Backpack

You’re probably as surprised as I was when I discovered companies make mountain bike hydration packs according to gender. 

However, it’s not quite the case, and there is a good reason for the name. According to Gap Year Travel Store, “The main difference you’ll find between unisex travel backpacks and backpacks for women is the shorter back length, which is designed to accommodate the generally shorter female torso. 

However, it is worth noting that many men can be on the shorter side, so may prefer to use a ‘women’s backpack” (2015) 

So, if you’re finding that even adjustable packs seem to swing and jiggle uncomfortably on your back; whether you’re male, female, non-binary or whatever the case may be, in terms of fit this will probably be the best hydration pack for mountain biking for you. 

What with the smaller size and all, Osprey had to make sure that space wasn’t compromised, and ensured this through tactically positioning the pockets and compartments around the pack. 

At a glance, it features the following: Contouring AirScape back panel and bike-specific shape harness, a LidLock bike helmet attachment, a zippered, scratch-free slash pocket for sunglasses and stretch mesh zippered hip belt pockets. 

Furthermore, there are dedicated lower compartments that hold the included roll-up tool pouch to organize bike tools. Here’s the real kicker, despite its reduced size, this backpack has an increased 2.5L capacity Hydrapack, bigger than most standard 2l packs. 

Neboic 2Pack Hydration Backpack with 2L Hydration Bladder 

To conclude the list, I could not help but include possibly the best deal on the entire list in terms of hydration backpacks. 

This product is mostly aimed at couples (couples that ride together, stay together), riding partners, or really any other duet configuration of riders.

Why you ask? Well, with this product, you get not one, but two packs for one incredibly low price.  They are compact and low-profile hydration packs, perfectly tailored to lightweight pursuits like running, mountain biking and ultralight hiking. 

They feel light and stable on your back and won’t create any wind resistance, as they are incredibly aerodynamic. 

They feature 3 Extra Pockets -Including one easy access mesh front pocket and other 2 zippered side pockets will ensure you enough space for any of the different essentials you may need to carry. 

It is made out of high-quality materials, and has adjustable hip belt and shoulder straps that can be modified to fit your torso.

How to Choose Hydration Backpacks

Now that you’ve had a good look at the best hydration packs for mountain biking currently on the market, there are just a few things to be taken into consideration when choosing the best one for you:


The size and form factor of the bag are extremely important factors to be taken into consideration when choosing the best bag for you. 

You seriously don’t want to buy a bag only to find out that its too tight for your frame, or that it swings around like a monkey in a banana tree on your back. 

Always pay attention to the dimensions of the bag you’re interested in, and always check the ‘female’ options, because in my opinion they sometimes have a better sizing and fit even for larger people such as men, if you’re going for a minimalistic, hydration-oriented setup for light travel. 

They both come standard with 2 litre (70 oz) hydration bladders, which is the perfect size to offer a nice balance of reasonable weight and bulk while providing a sufficient quantity of water. 

The drinking tube easily disconnects from the body of the water bladder which makes I super simple to refill. Furthermore, the wide-mouth openings allow you to fit a hand inside the backpack water bladder, which makes cleaning easy and can accommodate for ice cubes. 

An awesome option for a gift idea, or if you have a riding buddy that’ll split the cost with you, everyone wins!


The overall capacity of the bag should be considered, both as a factor of how large the bag will be, and how much it can store. 

Now, usually companies will include the total bag storage capacity, but also the capacity of the included hydration bladder. 

It is usually around 2l, but there are obviously exceptions within the products listed, to suit your personal needs. 

Your bag should be capacious enough to fit your liquids, and then depending on how much extra you’re planning on bringing with on the average ride, should have space left to accommodate that. 

Storage (of other necessary items):

As was just mentioned above, many riders choose to ride with extra items on them, such as extra layers of clothing, helmets & spares, light snacks like granola bars or fruit, or even just valuables like cell phones, glasses, wallet and keys etc. 

If you want to calculate the potential amount stuff that you can stuff into the bag, take the hydration bladder amount (in L) and subtract it from the total bag’s capacity amount (also in L), and you’ll know roughly how many riding essentials you can fit in alongside your hydration. 

Bite Valve:

This is a nifty functional design shared by many of the hydration packs on this list. A bite valve features a soft silicone cap, which in its default position seals the mouthpiece. 

Upon a light bite on the soft part of the valve, the valve is deformed in a way that water can pass and allows you to drink. 

This is a pretty ingenious way of utilizing an on-the-go hydration pack, as some do come with “finger pop lid mouthpieces” (no idea how else to describe them), but these require you to either have a hulk-like jaw strength, or use your fingers to pop the stopper open. 

With the bite valve, you can simply drink on the move, hands-free. This makes for a much smoother and more efficient hydration system. 

Harness Style and Comfort:

A large factor determining the overall comfort, fit and experience of your backpack will come solely from how the pack fits you, and to what degree the straps are modular and can accommodate your build and chest dimensions etc. 

While many of the packs feature high-tech foam padding and cushioning technology, if the straps cannot accommodate your overall shoulder/chest shape, the bag is either going to dangle and swing around on your shoulders (not secure enough), or make it feel like your brain is getting squeezed through your helmet (too tight). 

Finding that sweet spot can be tough, but we recommend that you take the necessary measurements of yourself before buying your hydration pack. 


You’ll notice that on many of the packs foam back padding, or on the straps there is webbed ventilation. On the well designed and put-together hydration packs, these ventilation holes should serve two purposes. 

Number one, is to keep your back and shoulders from sweating and overheating too much, as having a pack tightly pressed to you during an exertion on a ride will probably get sticky. 

Secondly however; and we saw mention to this in a few of the product features, is an intelligent air-flow system to keep your liquids cooler for longer. 

Much like the intake on the car, the rushing of air from riding at speed in the outside air will flood your bag and keep not only you, but your liquids cool. 

In some cases, coupled with thermal insulation, this technology can keep your fluids (and pits :P) cool for up to 4-6 hours!

In Conclusion

Wow! More to the best hydration packs for mountain biking than you’d think huh? They truly are revolutionary pieces of kit to the sport of mountain biking. 

I don’t know about you, but 2l plus of ice-cold water at the finish line sounds an awful lot better than a tepid 500ml of water in your crusty old hand-me-down water bottle that’s probably full of BPA and last year’s mud in the nozzle. 

However, you do need to take care of these pieces of equipment, and if you buy one make sure to wash them regularly as they will get full of saliva and nasty debris or mould over time if you neglect them. 

Warm water and a tablespoon or two of baking powder should do the trick! Besides that, remember to stay hydrated and always pack more water than you think you’ll need, and keep on pushing!
