Our hydration pack buying guide

It’s only natural to prefer riding bag free. However, the facts are, the good old saddle bag or jersey pockets just won’t do – more so the case for longer rides, where you’d need to carry supplies and extras in preparation for the unknown. Fortunately, there happens to be a functional solution for mountain bikers’ storage space problem, hydration packs.

Now, it’s understandable not to be all excited about carrying trail packs while out on your epic adventures. But when your trail is deep in the backcountry, or you’re engaging in all-day rides, bikepacking, and of course while mountain biking, this humble piece of gear is an absolute necessity.

What type of Hydration pack do I need?

Naturally, the first question to come to mind before purchasing a hydration pack would be if you need one at all? The easiest way to answer this is to know the categories of hydration packs; that way, you would know where you fit in.

The first variety is lightweight hydration packs, perfect for an XC-nature ride under about an hour, and typically holds about a liter of fluid. The Camelback Chase Vest is an ideal example.

The more common category is the trail pack. These hold roughly 2 liters of water with sufficient room for tools, food, and basic supplies. A good example is the Vibrelli Hydration pack.

Finally, the third class is the all-day hydration pack. With a storage space of 10 liters, you can rest assured of more than enough room to carry a nice lunch, tools, extra layers, and yes, plenty of water, to name a few.

Seeing these types of hydration packs, the answer to your question of whether you need a hydration pack is another question – do you want to be prepared for the unknown when out on a trail, or you enjoy the adventure of being stranded and in need out there?

If you are for the former, then there are a wide variety of comfortable packs for long rides and vigorous outdoor activity, small batches to store essentials for shorter rides, and even unique hydration packs best for specific activities like skiing. So, how do you now tell which hydration pack is best for you, and what do you look out for?

Hydration pack size

Since we’ve already mentioned the major categories of the best mountain bike hydration bags regarding size, this is easy to understand.

Mountain biking requires slightly more hydration and supplies than many other outdoor activities. Of course, mountain bikes have increasingly become reliable. There is still the persistent possibility of broken chains and flat tires, among other unforeseen predicaments. Hence, mountain bikers should look to get the best packs with average and above storage capacity.

As a rule of thumb, hydration packs for mountain biking should be between 8l -15l. These usually allow bladder capacity of 2-3l along with storage capacity for essentials. As a bonus, they also sometimes come with fleece-lined pockets – for that extra layer – which is perfect for carrying cameras, goggles, and sunglasses.

Fluid Capacity

In line with the hydration pack’s size, it is equally important to know in specific the water (or any other liquid) capacity of the hydration pack as It is the major reason you’re carrying one in the first place. Most of our favorite water packs for mountain biking accommodate 2 to 3 liters of water, which we consider to be plenty for most hard riding adventures—certainly, more water and weight. Hence, you would need to consider how much water you need for a ride instead of packing up unnecessary weight.

Nonetheless, we recommend the 3l packs (which is equivalent to 4.5 water bottles of standard size) since they have minimal weight but can carry enough water as the plan or situation requires. In planning the amount, you need to take. You just have to experiment and find out how much water you consume, how long you’re spending on the trail, then the temperature and the accessibility of refills.

These factors would help guide you to how much you drink and, as a result, how much you need to carry. However, it is noteworthy that some hydration packs do not come with bladders, so ensure to crosscheck before your purchase.

Harness and Straps

The best hydration packs are indeed one-size-fits-all. Nevertheless, without a more personalized fit, you might end up with the trail pack whacking you in the back of your head once you hit any steep spots or quite the sore shoulder on returning home.

Good mountain bike water packs usually include ventilated shoulder straps, accompanied by a much-needed sternum strap for maximum adjustability and comfort. Some of the best hydration packs also include suspended mesh backs as well.

In buying, consider your torso size and waist size and pick one that matches up accordingly with your body type. In a case where you can’t try them on, make sure to pick trail packs with the maximum adjustability and ventilation, I.e., sternum straps and channels at the back panel, respectively.

Other features

In specifics, some of the most popular and agreeably best hydration packs for mountain biking especially are the CamelBak MULE LR 15 and Osprey Raptor 14. This is because of their unique features that are specific to mountain bikers.

The CamelBak MULE LR 15 has a low rider hydration system, typical for lumbar water reservoir enthusiasts. Then the Osprey Raptor 14 is an even more recognized counterpart, loaded with specific features and considered the best hydration pack for mountain bikers.

All things being equal, you can assume that if a package works great for mountain biking, there shouldn’t be any other activity it won’t perform excellently at.

Essentially, try to look out for features that’ll enable you more on your trails. Some of the most recommended features include secure bite valve storage, quick access waist pockets, wide-mouth bladder openings, helmet holders, or a waterproof cover.

Final Thoughts

If you are an active person who love the outdoors, a hydration pack will be one of those gears or items that is essential. It is easier to move with it and it frees up your hands to do other things like supporting yourself while you are being active and adventurous.

Hydration backpacks come in many different shapes, form, design and even brand and some are made specifically for certain activities. If you’re a cyclist, you’ll probably be looking for the best hydration pack for mountain biking while someone who loves hiking will be looking for the best hydration pack for hiking.

If you involve you’re kids in you’re adventures, then you’ll probably be looking for the best pack for kids. While most brands make multi-purpose hydration packs, some also make packs suitable for activities from walking, running to mountain biking.
