How To Buy a Great Hydration Pack For Water on the Go

Hydration packs have built-in access to water you can drink while you’re wearing the pack. They come in many designs and sizes, specialized for activities like hiking, mountain biking and running.

Like a camel, these packs are equipped with a special bladder that lets you carry all your water on your body; you just drink it through a special straw.

Consider these factors when choosing a hydration pack:


It’s not surprising that the CAMELBAK M.U.L.E. ($115, has long been a bestseller. With a narrow profile, moderate weight, multiple pockets and features, helmet attachments and a 3-liter bladder, it’s a favorite for mountain bikers, but crosses over seamlessly to hiking and other sports that don’t demand an ultralight pack. With 12 total liters of cargo space, it swallows extra layers, tools and food for a multi-hour adventure. 1 lb., 6 oz. The KIDS’ MINI M.U.L.E. ($50, holds 1.5 liters. 7 oz.


Does it hold enough water and other stuff for your needs? Water capacity often ranges from 1.5 to 3 liters, plus just enough space for a light shell jacket and snacks — perfect for a long day hike.


Whether on the trail or around town, the GREGORY NANO 18 H2O HYDRATION PACK ($70, delivers basic functionality at a good value. The Nano 18 offers a magnetic sternum strap to hold the bite valve when not in use. The bladder holds 3 liters of water and has its own designated pocket. 1 lb.


Mouthpiece-hose designs vary; some are much easier to clean, which matters if you’re adding a drink mix. Some have magnets for attaching the hose to the pack’s sternum strap.


For mountain bikers, the OSPREY SYNCRO 12 ($130, scores high on every measure, from comfort, support and fabric breathability to ease of use, accessing contents, drinking or refilling water. Its 12 liters of gear space will hold your extra layers and food, and the trampoline-style back panel and shoulder straps shaped for the way your arms reach forward onto handlebars provide superior comfort. The pack’s reservoir can hold 2.5 liters. 1 lb., 11.5 oz.


A pack for, say, mountain biking will often be too heavy for running but might cross over nicely to hiking.


For ages 8 to 12, the REI TARN 15 ($60, is a light all-purpose hydration pack for virtually any activity. Padded shoulder straps, a ventilating back pad and a thin webbing belt give it comfort for carrying several pounds. The Tarn sports enough capacity for clothes, snacks and incidentals, and features multiple pockets, a 1.5-liter bladder and durable materials. 15 oz.


Will it fit you? The smaller designs come in one size or a couple of unisex sizes, while larger packs have two to four gender-specific sizes.

You’ll want the pack to fit snug and not slung low on your lower back, otherwise it’ll cause painful pressure and bounce around like crazy while you’re moving.


For girls whose shoulders and back length don’t yet fit an adult pack but have outgrown a kid’s pack, the OSPREY KITSUMA 3 ($65, fits the bill. The low-profile shoulder straps and slender body, along with the mesh back panel, keep the pack stable and you cool. The 2.5-liter bladder supports longer trail outings, and a pocket holds small items. The OSPREY KITSUMA 1.5 ($55, fits kids under 5’6″ better. 7 oz.


Does it have the features you want? If you have one use in mind, there are specialized packs for it. For example, running packs and vests are slim and light, have multiple pockets within reach while wearing it and tend to ride high on your back — some hikers might like them, too. For multiple activities, find a multipurpose pack.


A mesh harness that makes the pack almost unnoticeable on your back and a secure, zippered pocket for a phone makethe CAMELBAK CLASSIC ($60, a top choice for short adventures. A sleeve holds the 2.5-liter bladder. 5 oz.


If you don’t keep your hydration pack clean you’ll risk getting sick. If you leave water in something for a while, it gets stale and can develop bad bacteria.

If you’re lazy, look for something dishwasher-safe. (It should say so on the label.) Hydration packs are notoriously tough to clean. The easiest are ones that have openings large enough for you to stick your hand inside. Some have detachable hoses, but to really get one clean, you may need to buy a special brush.


If your hydration pack springs a leak or gets too old, it’s easy to buy a replacement reservoir without replacing the entire pack. These water bladders can also be used to convert any daypack into a hydration system.

The OSPREY HYDRAULICS 3L RESERVOIR ($36, has a backerplate to provide structure and make it easier to load into a full pack. It also has a handle to make it easy to pull out. The loops on the right and left side of the carry handle allow you to customize which side your water hose is hooked on.

The Big Bite valve on the CAMELBAK CRUX 3L RESERVOIR ($35, delivers 20 percent more water per sip. The valve self-seals to prevent unwanted drips.

    Thanks for the information !!!😃😃😃😃😃😎😎😎😎

  5. Camelbacks are great! Its much easier to run with them than to strap a Nalgene to your shorts!

  6. I have numerous CamelBaks of different sizes. I like the packs with no frills. What I mean by this is no or few pockets. The reasons for this is they are less expensive to purchase, you have the convenience of putting it in a daypack or a backpack or wear it by itself. You have the insulation of the pack and it protects the bladder from sharp objects. And last but not least, in the winter you can wear it under your jacket to keep it from freezing.

  7. My Camelbak is amazing

  8. This really helped!!!

    Had a Camel-bak and Sierra blatter but opted to go back to my good’ole Nalgene bottle with a Nalgene Canteen as a back up. Works best for me and is the easiest to clean of any other option. Sometimes simplicity is the best; you just may need to try other options to realize it.

    i love my camelbak

  14. Get either a 32 Oz. Nalgene or a Geigerrig Reservoir, you can pressurize it with an included pump and spray it.

  15. the badlands hydration pack is very good for hiking and camping and is not very heavy

  16. Camel-bak: I broke the hanger hook while on a BWCA trip; wrote to the company and they sent me a new system and said keep the old one. I’ m sold on customer service. A+.

    • Camel-Bak has never let me down either, they can take abuse and keep on pumpin’. It’s for this reason that I have had two while in Iraq and Afghanistan and have another that I use for backpacking, camping, and biking.

  17. I need a spare bladder for a hydration pack please reply

      I highly recommend SOURCE hydration packs. They put on a special coating that keeps the water from tasting bad even if it has been in the hydro pack for a long time.(don’t worry, the coating isn’t toxic) and they have dust guards. I got my two liter pack for $16.99 at Cabelas. Which is pretty darn cheap for a good hydro pack! look on Amazon or ebay too!

    Where can i find a really cheap,heavy-duty, hydration pack in Des-Moines, Iowa and surrounding areas

  19. I am looking at the camelbak lobo so that i have a small pack with a removable bladder. I currently use a philmont nalgene, two camelbak better bottles, the camelbak big chill and a platypus softbottle. I carry them in a small hydration pack without it’s bladder (it got a leak).

  20. attention. I am changing my name from Delta Force to Delta 8 because that was my squad’s name while I was a Spec-ops Paratrooper.

  21. A Camel-bak blatter is a great system for water, but if you like to add the flavoring then it’s a lot of maintainance work. If you do not clean & dry it properly mold can result. You’ll need the cleaning kit to do this ($15.00). For the sugar scouts, use a Nalogene bottle. Works great and is easy to clean; soapy water soak and wash or use the dishwasher.

    The platypus is very cheap and affordable. they are quite difficult to clean unless you by the accessories, and mine has formed a slight yellowish/brownish tint after a week at tomahawk scout reservation.
