With a volume of 20 L the Oasis is a total hit and a long time bestseller. That’s not a surprise because the quality completely outweighs the price. The pack comes with a BPA-free water bladder with a capacity of 3 L and large enough 6-inch opening for easy cleaning. The super comfortable and adjustable fit is convenient for both men and women. Thanks to the excellent storage capacity organized with plenty of external and internal pockets, you’ll have the freedom to take tons of gear on your hike.

Weighting only 2.45 lbs. (1.1 kg) when unfilled, this daypack is compact and lightweight enough for you to wear it comfortably for a long time. Let’s look at some important pros and cons so you have a better idea how the Oasis 1200 performs.

What We Like
  • Included rain cover for extra protection of your precious essentials in heavy rain.

#2 Mubasel Gear Insulated 

Mubasel Gear Insulated

Click image to see price.

Another high-rated bestseller, Mubasel is a hidden gem! What makes this backpack great is the presence of many super useful features and the mind-blowing price. With Mubasel, you’ll be able to enjoy drinking cold water for longer because the 2 L bladder is insulated. It keeps your liquid cool for up to 5 hours in the heat. For your convenience, the pack comes with a brush cleaner for the water tube. The breathable mesh padding on the back panel, shoulder, and chest straps makes walking on long distances an enjoyable rather than difficult experience.

What we found strange is that the volume of the backpack is officially unknown. It’s mentioned nowhere. Based on our observation and comparison with other packs, it should be approximately 15 L. Other than that, the weight of the pack is excellent for its size – 1.5 lbs (0.69 kg), thus allowing a comfortable day hike.

What We Like
  • Extendable and secured with a cover bite valve for maximum hygiene and protection – drinking water from it through the water tube is effortless and quick.
  • Plenty of options for storing various-sized items including a grocery zippered pouch, a meshed pocket, and waist-strap pockets.
  • The insulation of the bladder and the hose is not a hoax – it works after testing. No leaking and the large opening allows you to put ice cubes in the bladder.
  • Prevents rubbing and allows extended wearing thanks to the foamed ventilated back panel and athletic cushioned built of the shoulder straps
  • Great stability and fit because of the adjustable ergonomic chest and waist belts and improves safety thanks to the reflective design, and the integrated whistle on the chest buckle
What We Don't Like
  • Not as waterproof as advertised / no rain cover included

With its versatility, awesome fit, and amazing comfort, HydraHike is excellent for day hikes and cycling.

What we love about this pack is that it feels like a feather. It’s only 1.72 lbs (0.78 kg). Sure enough, it’s not just the weight but the fit that matters.

It has a first-rate 2.5 L water bladder that will allow you to seamlessly hydrate on the go.

Gelindo 18 L Insulated

Click to see price.

If you are looking for a multi-storage hydration pack at a reasonable price, then you’ll find Gelindo very interesting. This buddy has a 2.5 L water reservoir stowed in an insulated sleeve. The result is a cooler liquid that stays like that for up to 4 hours, thus making your hike easier and even more enjoyable. The capacity of 18 L is cleverly organized with plenty of pockets and compartments on the right place that will ease your packing and allow you to take various gear, clothes, food, medical kit, and a 13” laptop. Seriously, give it a look.

A nice benefit of the Gelindo is that it’s not heavy. The rucksack weights 0.9 kg or 1.9 lbs when not filled which is OK. To be honest, that doesn’t come as a surprise given the thin fabrics. Here’s the rest of our verdict.

What We Like
  • Good quality of the water bladder. It has a large opening, the hose is easy to remove and has a clip on the left strap for easy access. The mouthpiece has an anti-dust cover which is practical and the water flowing is decent. To stabilize the reservoir, there’s a Velcro fixing in the hydration sleeve which prevents shifting.

Buying Guide & Advice

So far so good, but how you decide which hydration pack would serve you best?

It’s true that there are plenty of options on the market and it’s easy to get confused.

In this section, I’ll help you better understand how to make the right choice for you and pick a pack that will be comfortable, reliable, and priceworthy.

First things first.

Understanding Hiking Backpacks With Water Reservoir

If you have never used a hydro backpack before, it’s necessary to grasp the conception of how do hydration backpacks work as well as their pros and cons. It will give you a firm understanding of what to expect when owning a pack with a water bladder.

In brief, a hydro pack allows you to drink water on the go thanks to a sip hose that is connected to a reservoir which is stored in a dedicated sleeve.

The drinking tube hangs over one of your shoulders and passes through a tiny hole in the backpack. On its end, there’s a bite valve or the so-called mouthpiece that you bite to allow water flow.

Here’s a nice illustration for a better understanding.

hydration packs infographic

You refill the bladder with liquid by disconnecting the tube (if the specific model has this option), pulling it out of the sleeve, and filling it with water. Usually the opening of the bladder is large enough so that you can clean it easily and even put ice cubes into it. After that, you carefully stow the reservoir back in the pocket, reconnect the hose and you are ready to go.

In terms of volume, it’s good to know that most of the hiking rucksacks with water reservoir are daypacks. That means their storage capacity is roughly in the range of 6 – 30 L. Keep that in mind.

Don’t prepare for thru-hiking or long backpacking trips with your hydration pack on your mind. It’s designed to accommodate a 1-2 day adventure or a short overnight hike.

Regarding the capacity of the water bladder, the most common volume is between 1L – 3L.

Why It’s Beneficial To Use A Hydration Backpack

The main benefit of hydro packs comes from the unmatched, seamless hydration they provide.

You don’t need to stop or slow down your pace and fight your access to the water bottle that is often difficult to reach, stored in a side pocket.

You just bite the valve while walking and you drink water a second after you thought about it.

Using a pack with water bladder is also incredibly handy when you walk on technical terrains during hot summer days. Often in such cases, you need to drink small sips of water every 10 minutes without wasting time and energy to stop and pull out the bottle from a pocket.

Furthermore, having a hydration pack allows you to carry bigger amounts of water (up to 3L) more comfortably. Often, putting one or two water bottles in either side pouch disturbs the overall balance of the load, making your backpack swing side to side.

Having a water bladder is much more convenient because of its ergonomic shape. It easily allows the reservoir to fit closely to your back. In that way, the load is distributed more evenly which is crucial to your stamina, back health, and comfort.

What To Look For When Buying A Pack With Water Bladder

Let’s begin by something that you don’t want to overlook.

Health Considerations

Probably the most important thing you have to pay attention to when purchasing a hydro pack is whether the reservoir is BPA-free.

The abbreviation stands for the industrial chemical bisphenol A. It is found in plastics and without entering into details, do know that it’s dangerous to health. That’s why always look for bladders that are marked BPA-free and FDA (food and drug administration) approved.

hydration bladder

The hydration system should always be BPA-free and FDA-approved. Image via Toytoy.

Usually some manufacturers even give certificates stating their reservoirs are harmless and free of this chemical compound. Be careful when choosing a pack from low-budgeted, shoddy brands. All of the respectful names in the industry produce bladders that are BPA-free and FDA-approved.

You will find that all backpacks in our list obey to this health standard too.

Hydration System Considerations

You are purchasing a hydro pack so undoubtedly you want to be able to drink water effortlessly with it.

First off, it’s best to decide on the volume capacity of the bladder. To ease the decision, you need to compare it to the overall volume of the backpack.

Will you have enough space left for your gear once the reservoir is full? Are you going to use the pack for longer hikes or short day adventures?

Know that often, it’s possible to change the bladder. That means you can put a smaller or a bigger water reservoir in the sleeve. Make sure to verify if that’s doable, though.

You can to that by reading all the information and customer reviews about the pack. Don’t hesitate to ask relevant questions the seller or contact directly the manufacturer.

Second off, inform yourself how easy the water flow passes through the sip hose and reaches the bite valve. Many cheap brands fail on that and this is something that could be pretty annoying on the trail.

Another important criterion is whether the water bladder is leak-proof and puncture resistant. Again, be careful with the cheaper brands. Read as many customer testimonials as possible.

Yes, you can always change the bladder if something happens, but it’s best to spare yourself the time and money.

Watch the video below which gives some useful insights on the topic.

Depending on your budget and preference, it’s not a bad idea to invest more money on some cool extras that will contribute to your comfort and better hydration. For example, you can choose an insulated bladder that keeps your liquid cold for hours.

Furthermore, you may have a pack whose bladder have the option to dry fast thanks to its design and ergonomic shape. That helps eliminate bacteria. Some of the bladders even have dry hangers, which often comes in handy too.

Last but not least, you might want to consider a hydration pack that has an anti-dirt cover on the mouthpiece. This is great because it protects the bite-valve when you put your pack on the ground. Something that’s especially useful is having a magnetic clip on the chest strap or on the shoulder strap where you can position your sip hose for easier access.

So consider every option and decide whether or not you need those additional features. Always think long term.

General Backpack Considerations


That’s the most important thing about a hiking backpack. You can a have great capacity, excellent fabrics, lifetime warranty, and many other perks such as an integrated rain cover, for instance. But all that doesn’t matter if the pack feels uncomfortable on your back. If that’s the case, it’s unwearable.

Here’s what to look for if you want to make sure you’re choosing a good backpack:

  • Good fit and adjustability – the rucksack should be easily adjustable to fit your frame. You have to be able to adjust the shoulder, chest, and waist straps seamlessly. The pack should ‘embrace’ your body.
  • Decent ventilation and padding – look for packs that have ventilated back panel that evaporates the sweat and doesn’t retain the heat. Padding is important on the back and at least on the shoulder straps to prevent rubbing.

That’s it.

These are the basics. If you have that, you will feel good while wearing your backpack. You can make compromises with every other feature to achieve a good price. However, we highly recommend you go for a pack that have the basics. It’s important.

The good news?

Most of the packs these days have those options. And all the packs described in our list above have them too. Sure enough, some backpacks are better than others in some aspects.


Comfort should be your first criterion when looking for a backpack.

Therefore, based on your needs and preference, you have to decide what’s most important to you – to have better padding or better ventilation, for instance. Of course, you can have both but in that case, it’s highly likely that the price will be bigger. By the way, if the price is a serious factor for you, check out the best cheap hiking backpacks of 2019.

Here’s our advice on what else to look for when it comes to other additional backpack features:

  • Sturdy materials – the higher the denier of the nylon or the polyester, the higher are the chances that your pack will last you longer. Plus, most of the waterproof backpacks are made of rigid materials.
  • Enough storage room – that not only means big overall volume measured in liters. Aim for a pack that has multiple compartments and pockets so you can organize your various-sized items correctly.
  • Internal frame – the presence of an internal frame is related to the volume of the pack but if you’re buying a rucksack that’s over 25 L it’s best if it has an internal frame. It makes it more solid and stable.
  • Suspension system – that’s an integrated mechanism that combines ventilation, adjustability, and ergonomic design. It’s essential for you comfort. A good suspension system reduces strain and fatigue and distributes the weight of the load evenly all over your body.

Honestly, you’ll be good if you pack doesn’t have other features.  Everything additional comes as a bonus. An integrated rain cover? Yes, it’s pretty handy but not essential. A safety whistle or a small pocket for your shades on the shoulder strap? It’s awesome but again, not absolutely necessary.

I hope you get the idea.

Price Considerations

Depending on your budget, you will face different dilemmas.

If you’re looking to buy a cheaper hydration pack and that’s roughly below $60, then inevitably you will have to choose between quality and price.

In most of the cases, there’s an unavoidable trade-off between price and quality and this is something you should keep in mind. Of course, there are many exceptions.

It’s true that there are some hidden gems. In fact, in our list you’ll find packs below $40 that perform surprisingly well. Still, there’s some sort of a trade-off involved.


Often, but not always, the price of a pack is a quality factor.

Either the hydration system doesn’t work so well, either there’s no good ventilation on the back panel. That’s why we included a Pros and Cons section in our reviews.

When you’re looking for a hiking pack with a water bladder, you’re not only purchasing a backpack or a hydration system. You’re purchasing a hydration backpack with a hydration system, as a whole.

It’s important that your desired pack performs equally well both as a backpack and as a hydration system.

If you want to achieve that, then most probably you’ll have to sneeze more than $70. Typically, it would be something in the range of $80 - $130.

Our advice is to be ready to invest more money on your next hydration backpack while at the same time keeping an eye on the cheaper packs.

As mentioned above, there are some hidden gems among them that definitely deserve your attention.

Think of the process as a long-term investment that will enhance your life. It’s true.

Tips For Maintaining Your Hydro Pack

If a standard backpack needs a good care, a hiking pack with water bladder requires a little more effort to stay in a good shape for longer.

Don’t be scared, though, it’s nothing complicated.

Always clean the reservoir after each use and let it air dry completely before using it again. Rinse it with hot water. You can use baking soda or dish soap for maximum effect. It’s easier if you scrub it with a brush too.

If you use it for the first time, it’s possible that you sense a plastic or rubbery smell. To eliminate the odor, wash the bladder with a bleach or with a lemon juice. It helps a lot.

Don’t use any other liquids but water in the bladder, especially alcohol or milk.

Enough with the dos. Let’s talk about the donts.

Don’t use any other liquids but water in the bladder, especially alcohol or milk. That will help prevent bacteria growth. Also, it’s important not to expose the reservoir to UV lights for long periods and to extreme temperatures.

Avoid using it extensively when the temperature is below - 20° or above 40°.

Keep those elementary rules and your backpack will serve you well for many years.

Hi Asen, thanks for the excellent review. It’s full of details and you covered some points I have not even considered.
For example, you pointed out that some reservoir might not be BPA free. Especially those substandard backpacks.

    Asen - July 11, 2019

    Most welcome, Fred!

Kat - July 12, 2019

Wow, such a thorough in depth review of a wide range of hydration backpacks. I have to be honest, I wasn’t sure if they accommodated for other stuff to be able to be carried too, so I’ve realised it can be. You know, when considering a hydration backpack, this really covers everything. For someone who hasn’t had one before, this is so helpful in knowing what to look for and what concerns or things you didn’t like about each one. Thanks heaps for putting it all together the way you have. Also, you’ve presented it so well, and makes it easy to read while figuring out which one would be most suitable for me. Thanks for a great post.

So I am going on a trek with a group suggesting a 26-4oL pack with a 3 L water bladder. i cant find one on your suggestions that fits that criteria. Any other suggestions?

    Asen - January 17, 2020

    Hi Vicky,

    I hope your trek will be exciting! I understand you need a pack with a slightly bigger volume and a 3L water bladder capacity? In that case a very good choice would be Rei Co-Op Trail Hydro 30 L or Gregory Citro 30 L. Feel free to ask if you have any questions. Have a great hike!
