Hydration Bladder Buying Guide

Hydration bladder’s main purpose is to make drinking convenient and efficient. This means not having to get a bottle out of the pack and opening them to drink then having to return them in the backpack. This is quite a challenge when doing outdoor activities like running, hiking or biking and will consume time and energy that you’re trying to conserve doing the tedious activity. With a hydration bladder, you just have to pull out the tub and sip away. No need to worry about spills or bottle caps.

With such a demanding task to keep you hydrated, it may be taxing to decide which hydration to buy. This article will walk you through the considerations; capacity, type of hydration bladders and fit, to help you decide which is the best hydration bladder for you.

What is a Hydration Bladder

The primary function of a hydration bladder is to carry your fluid supply. One of the many benefits of owning a hydration bladder is the ease of staying hydrated, effortlessly. Hydration bladders are specially designed packs that carry a bladder full of fluid. The bladder feeds a tube, which is then led over your shoulder then clipped in place on the bag strap. The benefits of hydration bladder are significant, here are a few to note of.

  • Easy to keep and stay hydrated – because of the tube extending from the bladder, drinking is now a hassle free movement. No need to stop what you’re doing, remove a bottle from your pack and put it back. You can continue what you’re doing while sipping water from the tube.
  • Since hydration bladders are meant to be placed between your backpack’s frame and fabric, no internal space is used. You can also opt to not bring any hydration bottle which will save you space too! Also, you do not have to worry about them being punctured as they are made from durable materials. 
  • Once you’ve finished up the contents of your hydration bladder, it becomes a very thin film of heavy duty plastic. No space is wasted carrying an empty bottle.

Hydration Bladder vs Water Bladder

These two are somehow interchanged on some occasions, so to avoid mishaps while on trial, let’s differentiate the two. Water bladders are meant to store water at camp or wherever you’ll be settling in. it is generally bigger in capacity and built compared to hydration bladders. 

A hydration bladder has a drinking tube and is much sleeker than a water bladder. They are specifically designed to attach to a backpack via the clip assigned at the top of the bladder.

Hydration Bladder Capacity

Bladder sizes typically vary between 1.5 liters to 3 liters. There are some day backpacks that cannot a 3L hydration bladder so it is best to check with your backpack too. However for most multi-day backpacks, the 3L can fit perfectly. How much water you should bring is really dependent on how much you drink when hiking, where’ll you be hiking (humid temperature makes us thirsty easily).

You can opt for a 2L hydration bladder like the CHERAINTI Hydration Bladder 2 Liter Leak Proof Water Reservoir for day trips or for when your camp has a clean water supply.

However, we suggest to get a 3L hydration bladder like the Wacool 3L Hydration Pack Bladder, if you hike all the time. Regardless if you’ll be day hiking or multi-day hiking. There is no hard rule that you need to fill in the whole capacity of your bladder. If you’ll be multi-day hiking, then by all means, fill it up. But if you’ll just be day hiking, you can fill up your 3L bladder with just 1-2 liters of water.

Quality

One of the key considerations in buying a hydration bladder. You would not want your water leaking in the middle of the hike and all your backpack is wet. Look for a bladder that is made of high quality plastic. Food grade or BPA free is a better choice to prevent any health concerns. Like the Laney 2 Liter Water Reservoir that provide you 2L of BPA free water.

Hydration Bladder Features

Bite valve: Check the bit valve mechanism of your hydration bladder. Some bite valves twist to open and close; others have a switch to keep water from going out when you don’t want it to. The bite valve of the HEIKLN 2-Pack Hydration Bladder 2 Liters has an on/off option to keep water from leaking.

Clips: Clips are a standard feature on common hydration packs to keep your tube positioned for easy access. We like the magnetic clip of the Osprey Hydraulics Reservoir that keeps the tube securely attached to the backpack.

Wide-mouth opening: wide opening allows you to refill the bladder easier, avoiding spillage. It is a great feature too when you want to add ice to your water. Cleaning the bladder to prevent molds from building up is also easier. Take a look at RESVIN  2-3 Liter BPA-Free Water Bladder that has a wide opening and extra long drinking tube. We also like the resealable bag design of WACOOL 2L Leakproof Water Reservoir, which can make cleaning and refilling a breeze.
