Features to Consider Before Buying

Now, while you are deciding on your hydration bladder, we’d like to give you a heads up on the list of features that you should consider before you make the purchase. Most of these features are common to most brands though ultimately, it all comes down to your personal preferences – don’t forget to take those into mind.

Size of the Bladder

The size of the bladder is one of the first things you should pay attention to. Hydration bags come in various shapes and sizes and you should pick one according to your needs.

Coming in sizes from half a gallon and more, larger bladders are suitable for longer trips – however, they will weigh more once you put them on your back.

On the other side, smaller bladders are ideal for day trips but won’t be much convenient during longer trips. The size of the bladder is also related to the bladder being able to fit into your backpack.

Bladder Opening

The bladder opening is very likely the second most important thing you should take into consideration.  In order to choose the most suitable opening for your needs, think about the environment you’ll be using the hydration bladder in.

It doesn’t matter whether it’s a zip top, a folding top or perhaps a screw cap – decide on the one that makes it easy for you to drink out of the hose. This feature will also help you estimate the refill time of the bladder – larger openings allow for faster refill time and vice versa.

Bite Valve Mechanism

The locking mechanism is a very crucial aspect that a lot of people often tend to oversee – you will need to keep the water inside the bladder. The switch and the turn valve are the two primary locking mechanisms available in the market from which you’ll very likely need to make your pick from.

We’d personally recommend using the switch type mechanism due to the ease of use. The turn valves may have a tendency to get stuck and may cause you to lose some valuable time when you’re out in the wilderness.

Pressurized or Non-Pressurized

Bladders can be pressurized or non-pressurized. Pick one according to your needs – both should be a pretty decent choice.

A pressurized hydration bladder squirts out water without any sucking action because of the presence of a pump inside one of its two chambers – it’s extremely convenient to be used! A non-pressurized is pretty much your standard bladder – you’ll need to suck the water out of the hose yourself.

Hose Compatibility

Most of the time, the manufacturers use the same dimensions for the hose making, so different hoses are compatible with different bladders. However, it’s always for the best to make sure yours has a standard opening – if not, check to see what other bladders it would be most compatible with.

This feature also means that you can get a new hose whenever the old one gets used up. Hopefully, you’ve gotten some basic understanding by now about the things you need to pay attention to. Let’s move to the part with the actual reviews now.
