Surprisingly, before the 1990s you would not have heard much about hydration bladders at all, never mind considering looking for the best hydration bladder money can buy. It was in the early 1990s that these convenient hydration units were made available on a commercial level.
The conveniences that a hydration bladder provides are myriad, and this is why they are coveted by cyclists, hikers, and other athletes who spend a lot of time outdoors. Of course, the chief convenience of the hydration bladder is the fact that they offer hands-free access to necessary water and fluids. Thus the athlete, cyclist, runner, or hiker can use the hydration bladder at any given time, even while working out without having to stop to do so.
The manufacturers of hydration bladders have continued to improve the features of these units with each passing year, and so there are a lot of options for those seeking to invest in a quality unit.
Backpack compatibility considerations
When you are exercising outdoors, it is vital that you remain hydrated and that you consume the right amount of water. If you are in normal weather conditions and you are an average sized athlete, you will need about 20 to 25 ounces of water per hour.
If the outdoor conditions are cooler and you are a lighter athlete, you will require only 16 to 18 ounces of water and hour. Finally, in hot weather, heavier athletes require as much as 28 ounces of water an hour.
Initially, before you can invest in a hydration bladder you will have to know what size you require and what bladder will be compatible with your existing backpack. Keep in mind that hydration bladders are, in general, similar in terms of their shape, but their size may vary and even with a similar shape you will sometimes note a few variations. Design differences are highly dependent on the manufacturer. The common sizes you can get hydration bladders and include all of the following:
- 1-Liter or 33.8 ounces
- 2-Liter or 67.63 ounces
- 3-Liter or 101.44 ounces
If you want to get the most bang for your buck, it is best to invest in the largest hydration bladder possible. When you buy the 3-Liter bladder you will pay about the same price you would for a smaller bladder and you will be able to get almost as much as three times the fluid you would get with a 1-Liter unit and almost 50% more fluid than you get from the 2-Liter option.
Just keep in mind you should only invest in a 3-Liter unit if it will actually fit into your backpack. Otherwise you will have a very tight fit in the backpack or you will be buying a newer backpack to go along with the unit: This means additional cost when making your initial investment.
Hydration bladder styles
Typically, there are two different styles of hydration bladders that you can choose from when you are looking for an exceptional hydration unit. The option to have before you include the zip top and screw cap hydration units.
The screw cap hydration bladder, of course, allows the user to screw the cap onto the bladder once it is filled with water. In contrast, the zip top unit looks a lot like zip lock storage bags with units featuring additional closure reinforcements.
With either selection, you will find the bladder quite easy to open and fill. If you will be filling the unit from a drinking fountain or a sink with a shallow basin, you will want the screw cap bladder unit because you can hold the unit diagonally or horizontally when filling it to capacity.
If you think you might be filling in the hydration bladder outdoors where you can access fresh spring water, a bit of trickling water or slow-moving or near still stream, zip lock hydration caps are a better idea.
The main advantage the screw cap bladder has over its counterpart is the fact that the user is capable of filling the unit to capacity. With the zip lock bladders, there is an area remaining for air to prevent spillage when closing it.
When first introduced, hydration bladders were actually hydration packs. Once consumer demand made it obvious that these packs were popular, backpack designers started making bags with compartments for the hydration bladder.
There are many different bags now allowing you to install a hydration bladder. The different designs determine how you insert the straw or configure the shoulder straps and drinking tube.
Cargo space and pack size
Hiking: Just as it is important to give consideration to the capacity of the bladder you intend by, it is equally important to think about the capacity of the cargo space in the backpack you will be using with the bladder. The biggest backpacks compatible with hydration units have 2,500 cubic inches of cargo space: This is equivalent to about 41 Liters.
The latter type of bag is ideal for overnight excursions. As an alternative, you can combine climbing packs with a bladder while still leaving 1,800 cubic inches of space inside the bag to carry your gear and personal items: This is equivalent to 29-Liters of gear-storing space.
Mountain biking: These types of packs give you a couple of options. You can opt for a light backpack with 100 cubic inches of space compatible with a 3-Liter unit or if you want something larger, there are options all the way up to 23 Liters or 1400 cubic inches of space.
In contrast, trail runner waist packs and road bike packs are small and light enough to ensure that wind resistance is minimal and the pack is going to be carried on the user’s back.
If you are a skier or you are into snowboarding, you will definitely want to have additional clothing with you whenever you are outdoors enjoying your favorite sport: If so, you can opt for the larger hydration packs coupled with the equally large cargo areas. Or, if you prefer, you can opt for a light bag in a small hydration pack.
For natural body heat will help in keeping the water from freezing so you can drink it.
Recommend volumes for reservoirs
The different reservoir options when it comes to hydration bladders are really ideal for specific situations. If you follow the guidelines presented here, you can ensure the bladder you select meets your hydration needs. Choosing the correct reservoir size will ensure you are carrying only the load you need to and that you will have all the water you need during your exercise/play sessions.
|Reservoir size||Recommended uses|
|1-1.5 Liter Hydration Bladders|
|Bike riding (recreational and/or short distances.) The lighter bladder and bag will ensure ease of transport and less wind resistance.|
Keeping children hydrated while they are enjoying outdoor activities.
Perfect for the minimalist who wants to deal with as little gear as possible.

Jogging/Running: The right size to not prove burdensome during exercise.
Short distance cycling: Little to no wind resistance.
Speed walking/Walking: Providing sufficient hydration for your walk session.
|3-Liter Hydration Bladders|
|Ideal in hot conditions of if you are a heavier athlete|
A must have in a region where water might otherwise be limited
Not recommended for someone in need of a light backpack unless you only fill the bladder part way when you need less water.
No matter what reservoir option you ultimately choose, you must know in advance that you want to use only water in your hydration bladder. Juices and sodas can clog up the hose of the unit in a hurry and are next to impossible to clean. You will also want to refrain from using milk through the sip tube because, again, it causes an issue with cleaning the unit.
Bite valves & sip tubes
When it comes to drinking the water in the hydration bladder, there are two means for doing so: via the Sip tubes or bite valves.
With the bit valve you have a small tube protruding from the bladder that acts as a mini-straw of sorts. The valve is made of polyurethane materials or silicone. If the bite valve is manufactured out of polyurethane materials, then it is likely the valve may produce a slight plastic taste when you are drinking the water – this is especially true the newer the bladder.
If you invest in the bladders fitted with twist on and off bite valves, you will find that these units are far less likely to leak. You can also expect to have to replace the bite valve as a few times over the lifetime of hydration bladder ownership. Experts recommend that you allow the interior of the bite valve to dry out or remove the bite valve and dry it out manually by shaking it.
A short stint in the sunlight can also help. To maintain the longevity of a bite valve, make sure you do not bite down on it too hard when using the unit.
Some bladders have hoses featuring a quick release for speedier cleaning of the units. The tubes are long enough to wrap up and around the body so the hose opening is near the face and mouth during exercise. Slits are available for positioning the hose so it can rest on either of the shoulders.
There may be a clip that will help in holding the hose in position as well. Finally, you might also find a number of winterization features such as bite cover valves, reservoir covers, insulated reservoirs, and insulated sip tubes are among the special accessories that accompany some hydration bladders.
About hydration bladder pressure
Some of the hydration bladders on the market today are pressurized and others are not. If the unit is pressurized it features two chambers in the bladder. You will use one chamber as a hand pump and the other for air. With a pressurized bladder, you can get water to come out of it without having to suck on the sip tube.
Bear in mind that hydration bladders do not need to be pressurized in order to be simple enough to use. With that said, the benefit of pressurized water while you are outdoors is myriad. Pressurized water makes it easier to clean things with greater efficiency.
Additional advantages that accompany the pressurized system include the fact that it is easier to keep the tube clean and free of debris: This, of course, does not mean you can forgo avoiding putting fluids in the bladder that are not recommended for the unit. If a manufacturer suggests that you refrain from putting soda, juice, milk, or any other beverage in the bladder it is best to listen lest you run the risk of voiding the product warranty. For the advantages you get with a pressurized hydration bladder, you will pay in a higher initial cost.
The system is also weightier than the non-pressurized counterpart is. The downside to pressurized systems is they are heavier, more complex and more expensive. So make sure that you really find the bonus uses worth it.
