The best hydration packs combine comfort, stability, and functionality.



This article was updated 10/22/19

Because packs allow us to be prepared out on the trail, we’ve continued to seek out updates to this list. We’ve added some great new packs with unique design characteristics to improve your carrying capacity out on rides. We’d love to hear from you if you’ve found a great pack that works well for your needs, what is it and what do you carry in it?
What to look for in a mountain bike hydration pack
Let’s be honest. Not all mountain bikers love (or are even willing to use) hydration packs. Too hot, too heavy, too clumsy, too bulky are among the most frequently leveled complaints. And we hear ya. For rides less than 2 hours, there’s simply no need to schlep around a pack — especially in this age of high functioning bum bags, SWAT-type on-bike storage (thanks, Specialized), and water bottles inside the main triangle (finally, Yeti). But for bikepacking, big backcountry adventures, all-day epics, and/or guiding, the humble hydration pack remains an essential must-have piece of gear. That’s why Mtbr has rounded up this list of the best hydration packs.

Packs that have a low center of gravity such as the Camelbak Skyline LR10 mean less clanking around when you’re bombing downhill.

But before we delve into our favorites, it’s important to know what makes the best hydration packs… the best. And what you need to consider when making your personal purchasing decision. In no particular order, you should be thinking about capacity, fit, and features. Of course you also need to make sure that the pack you pick is actually intended for shredding the gnar, and not running a marathon or hiking in the Himalayas. Assuming you won’t make that mistake, here’s a rundown on the remaining key considerations.

Packs that can carry a helmet and pads are highly sought after in these enduro-is-everything times.
Water Capacity
When it comes to capacity of the best hydration packs, we’re talking about both water (or whatever your liquid of choice is) and gear. It’s also worth noting that some hydration packs are not sold with water-carrying bladders, so make sure you check. As for how much water you need, first-off remember that water equals weight (about 2 pounds per liter), so just because your chosen bladder will hold a gallon of go-go juice doesn’t mean you should fill it to the brim every time you ride.

How much water a pack can carry and how it’s delivered is certainly one of the most important aspects of hydration pack design.

Think about how long you plan to ride, how hot is it, and if you can refill along the way, and then plan accordingly. As a very general rule of thumb, figure you’ll need to consume the equivalent of one water bottle per hour of ride time, and that a standard water bottle holds around 22 ounces (or .65 liters). And then unless your bladder has fill lines, use one of your water bottles as a measuring cup when you fill up. That way you’re less likely to haul around unnecessary extra weight that’ll just get dumped in your garden when you get back from your ride.

Cargo space and how it’s organized is a key consideration when shopping the best hydration packs.

Most hydration packs (including some of our choices for the best hydration packs) come with 2- or 3-liter reservoirs. That’s plenty for most riding adventures, remembering that 3 liters equals the capacity of 4.6 standard-size water bottles. That said, we prefer 3-liter bladders, which add minimal weight while availing a wider range of fill options.

The best hydration packs are vented to help keep you cool.

Before buying a pack decide what are your must-carry items and then choose accordingly.
Gear Capacity
As for gear carrying capacity, expect to encounter a wide of range of options, with most packs usually in the 5- to 15-liter range. Next consider how much gear you need to carry. This is obviously in part a personal decision. Some of us can sustain all day on energy gels. Others settle for nothing less than a turkey sandwich, chips, and a cookie.

The bigger the pack the deeper you can safely venture into the backcountry.

Same goes for tools and spare parts. Are you a member of the quick-fill-and-tire-plug-only crowd, or do you regularly ride with a spare rear derailleur, full suite of tools, and a space blanket? We figure that most riders on most rides will be fine with around 7 liters of cargo carrying space, while frequent visitors to the deep backcountry, bikepackers, and guide types may need at least double that. Just remember that more space means more fabric, which means more weight for you to lug around.

Cargo space and how it’s organized is a key consideration when shopping the best hydration packs.

Also consider how that space is organized. Simple packs may have just one big carry-all pocket, while more refined hydration pack offerings will include lots of compartmentalized storage so you can keep your chain lube separate from your lunch. That means bonus points for packs with easy-to-access pockets, fleece lined storage for valuables, a removable tool roll, and hooks and straps to carry your helmet, a removable chinbar, or body armor.

When you’re dropping in the last thing you want to be thinking about is your hydration pack.
Fit
Though most of the best hydration packs are one-size-fits-all, that doesn’t mean you can forget about fit. Indeed, you’ll want to consider your torso length and waist size, and ideally try on packs until you find one that matches up with your body type. And even if you can’t try before you buy, look for packs that are highly adjustable, which will increase the likelihood that your pack won’t be bonking you in the head when you’re dropping into sketchy steep rock garden.

Removable back protection such as what the Dakine Seeker 15L has is an attractive feature.
Key Features
We’ve already mentioned some of the key features to look for when searching the best hydration packs. But beyond cargo carrying space, compartmentalized storage, and ample fit adjustability, we look for the following: rugged bite valves, secure bite valve storage, easy bladder insertion and removal, quick disconnect hoses, and wide mouth bladder openings, which make them easy to fill and clean.

Extras such as tool rolls are a nice add-on feature found in the best hydration packs.

Other desirable features include built-in back protection, good ventilation, security clips for keys, quick-access waist pockets, and built-in rain covers.

Chest strap and waist belt functionality are another key consideration.

Okay, now that we’ve run through the main things you should be looking for when shopping, let’s get to the goods. Here in alphabetical order are our picks for the best hydration packs for mountain bikers.
CamelBak Skyline LR 10


Aimed at addressing the issue of hydration packs’ tendency for unwanted shifting when bombing downhill, the CamelBak Skyline LR 10 is designed to shift the bulk of its weight near the lower back while at the same time giving more support to the wearer’s lumbar region. By lowering the pack’s center of gravity, the rider maintains more stability on rough trails while also letting the upper body move more freely. Other features include ample pockets to keep gear organized, attachment for a full-face helmet and armor, and a magnetic tube trap to keep your hydration hose from flopping around. It also comes with a 3-liter reservoir, and the rear of the pack has a ventilated back panel to help you stay cool.

HydroFlask Journey 10


Designed around shorter rides in warmer temps, the Journey 10L blends a clean, compact pack design with a unique tech approach to keeping your water cold. Centered around Hydro Flask’s multi-part Cold Flow system; externally, an articulated back panel separates the pack from your body, letting airflow to both your body and your beverages. Internally, a reflective-insulated sleeve houses a 3l bladder (included) further reducing unwanted water warming. The final piece to keeping your water cold is the reservoir itself – HydraPak Isobound insulation works in unison with the other features to ensure that whatever is inside the reservoir will stay cold for more than four hours. What we like about the Journey 10 is it’s sleek, clean design mated with some unique technologies.

Feedback from our forums We found some great conversation regarding hydration packs in our Apparel/Protection Forum:
str8edgMTBMXer said: “Osprey Raptor 14…mine is 5 years old now, and it has been awesome! Replaced an old Camelback. I bought it because it is much easier to fill, it has much more storage options as far as pockets go. I wear it at work too in the summer, so it gets a lot of use. It has a 3 liter bladder. Osprey is reeeaalll good about replacing parts. When the clear rubber nozzle thing wore out, I e mailed Osprey asking for a new plastic cover. They sent 3 for free…I have heard that they send other parts the same way.”

Arebee said: “I have the Raptor 14 as well. I chose it over the Mule NV a few years back. The two were very similar, but the Raptor just felt more comfortable. I closed the clip on the chest strap in my car door and they sent me two for free to replace it. I really like the detachable tool wrap as well.”

Outrider66  said: “I just finished my first ride with the Camelback Rogue I bought recently. I was extremely pleased with it. Along with the good hydration hardware, ample capacity and good fit/function, it has 2 zipper pockets which perfectly fit the stuff I always carry – wallet, phone, car keys, bandana, about 2′ of toilet paper (for me, the most essential item – lol), and 3-way hex wrench. It has an open “pocket” where you can stuff a shirt, etc., plus a tire pump.
