The importance of staying well hydrated while you are running or engaging in other suchstrenuous physical activity cannot be emphasized enough.
But, as you have probably experienced already, it is pretty inconvenient to carry a water bottle with you (or two) when you are going for a run. Not only could it throw off the balance of your body while running, but it also requires you to pause your run in order to take a drink from your water bottle. This can get pretty tiresome after a while.
And if you put your water bottle in your backpack (so you don’t have to hold it in your hand while running, that requires an even longer pause from your running, since you have to take the backpack off, unzip it, and take the water bottle out before you can even take a drink. That makes hydration seem pretty tiresome.
So what’s the solution? Get a hydration bladder! A hydration bladder will allow you to stay hydrated while running without ever having to pause your run.
Below, we have reviewed the best hydration bladders for basically all of your needs. All you have to do is choose the one that suits you best. We’ve also included a buyer’s guide for your convenience.

When purchasing a hydration bladder, you may be overwhelmed by the dizzying number of options available on the market.
Hopefully this article has helped to narrow down and simplify the choices for you. But to help you further, here are the most important features you should consider when selecting a hydration bladder.
You want to carry enough water for the activity for which you plan to use your hydration bladder. But you don’t want to carry so much water that it becomes a strain on your back and you end up and the close of your activity with a bunch of left over, unused water.
Thus, you should carefully determine how much water you usually drink for a certain activity and buy a hydration bladder with the appropriate capacity. On average, a runner can expect to drink 4 to 6 ounces of water every 20 minutes (or 6 to 8 ounces of water every twenty minutes for faster than an 8-minute mile), but everyone’s body has slightly different needs. So figure out how much water you need for the activity you plan to use the hydration bladder with and select the capacity accordingly.
The mechanism that is used to open and close the bladder for refilling, cleaning, and draining is important. Look for a hydration bladder with a closing mechanism that is easy to use, wide enough to allow for easy refilling, and which allows for easy cleaning.
The closing mechanism is arguably one of the most frequently used parts of the hydration bladder, so make sure that you select one that suits your tastes and preferences. For instance, if you frequently refill water from public drinking sources, make sure the opening of the bladder you choose can do that easily.
Ease of Cleaning
This is a big one. Reusable water bottles and water reservoirs can be a breeding ground for pathogens of all kinds, so the hydration bladder you choose needs to be easy to clean. Otherwise, the bacterial growth will contaminate your water, keep it from tasting pure and fresh, and possibly make you ill.
Look for features like a wide mouth and a detachable tube. Also, the smoother the plastic is, the less purchase bacteria will be able to gain on the surface of the components. You may also want to consider a hydration pack with anti-microbial technology of some kind.
Another important feature to consider is the mouthpiece. After all, since the primary draw of hydration bladders is the fact that you can hydrate with minimal use of your hands (or hands free) while you’re on the go, getting a bladder with an easy-to-use mouthpiece is essential. A bite valve is a good feature to look for. Also, make sure that the mouthpiece seals itself and is free from drips and leaks; a dirt guard is another nice feature to have, especially in more outdoorsy settings.
A high enough flow rate is another vital aspect; you don’t want to have to spend a gargantuan amount of effort to get the water you need during your activity. Get a hydration bladder with high flow technology.
Other features that you may want to consider in your hydration reservoir include clips for securing the drinking tube to your backpack or an insulated wrapping for the tube. An insulated drinking tube will keep your water cool and prevent that first unpleasant burst of warm water.
