It is entirely BPA-free and FDA-approved, so you can rest assured that it is safe to use. It comes in multiple different colors and is decently stylish. On top of holding plenty of water, it also has two storage compartments for smaller items like your phone, snacks, and towels. The bladder pocket itself is insulated to keep your water cold.

They offer a 100% money-back guarantee for 90-days. If you aren’t happy with the pack after this period, you can return the pack with no questions asked.

Best Hydration Pack for Running: MIRACOL Hydration Backpack
Unlike my hydration packs, the MIRACOL Hydration Backpack is designed for running. It is incredibly lightweight so that it won’t slow down your run. It is designed to sit very slimly against your back, preventing it from creating any wind resistance. Because of this, it is also very suitable for cycling, where your back is often exposed to the wind. The shoulder and chest straps are adjustable, allowing it to fit most people comfortably. The straps allow almost complete control of how the pack sits, so you can adjust it for your preference and prevent the pack from moving up and down as you run. The straps are easy to adjust according to most customers.
A unique airflow system prevents sweat from building up underneath the pack and helps you cool down. A 2-liter hydration bladder is included with the bag. It is BPA-free and does not transfer a taste to the water. A small front pocket on the bag can hold everyday items like your wallet, keys, and phone. If you have any complaints about the product, the company will refund you or send you a new product per their warranty policy.
MIRACOl Hydration Backpack Key Features:
- 2-liter capacity
- Airflow system
- Adjustable straps
- BPA-free
Best Budget Hydration Pack: Vibrelli Hydration Pack
For those on the hunt for a cheaper option, the Vibrelli Hydration Pack is a good option. It comes in multiple color options and is gender-neutral. It looks very professional when compared to some other backpacks, as well. It features an easy-twist mouthpiece that doesn’t leak. The water flows very quickly when the mouthpiece is activated, but it won’t drip on your shoulder while you’re running. Because it doesn’t drip, it is perfect for hiking and cycling, where the bag tends to get knocked around a lot.
The bag does not transfer a taste to the water. It is made from medical-grade materials and is free of BPA and PVC. There are also multiple storage pockets included in the bag, allowing you to carry a few smaller items with you. Despite this, the bag is not bulky and weighs just 14 ounces by itself. The straps are adjustable, and it is designed to fit most people. The bag also comes with a 5-year manufacturer’s warranty.
The only downsides of this pack are that the waist strap is very short, which can limit the people who can wear it. Furthermore, the straps are narrow and thin, which raises durability questions. However, this pack is covered by a warranty, so you won’t be out much if it does break.
Vibrelli Hydration Pack Key Features:
- BPA and PVC-free
- 14-ounces
- 5-year warranty
- Lightweight
Best Kid’s Hydration Pack: CamelBak Mini Kids Hydration Backpack
Children will often need a smaller backpack just because of their smaller size. They also don’t need as much water because of their smaller weight. If you’re looking for a bag for your child, we recommend the CamelBak Mini Kids Hydration Backpack. The pack comes in multiple colors and designs, so your child will likely be able to find something they like. It carries 1.5 liters of water – more than enough for most children. It is incredibly lightweight and comes with a few extra storage pockets for small items. Reflective accents increase visibility in dim conditions.
The on/off switch system is straightforward to use, and an ergonomic handle makes refilling very easy, even for children. The Crux reservoir delivers 20% more water with each sip, and the mouthpiece is designed for preventing leaking. The back is made with a breathable mesh to help the user stay cool, and there is a stretch pocket that is perfect for stashing a poncho or extra layer.
The pack is designed with most of the features standard in adult packs. Only everything is mini-sized for children. If your kids want an adult-like bag, this one is the best option currently on the market.
CamelBak Mini Kids Hydration Backpack Key Features:
- Multiple colors available
- Holds 1.5-liters of water
- Kid-friendly on/off lever
- Comfortable
Best Hydration Waist Pack: Osprey Packs Seral Lumbar Hydration Pack
If you can’t wear a hydration backpack for whatever reasons, a waist pack might be useful. These aren’t as popular as the hydration backpacks, but they are equally as helpful during a run or a hike. We looked at a few different waist hydration packs, and the Osprey Packs Seral Lumbar Hydration Pack stood out as the best. It is a bit more expensive than some other options, but you are getting your money’s worth.
It comes with a 1.5-liter reservoir and a magnetic hip valve attachment. Unlike some waist hydration packs, it has an actual mouthpiece and tube, so you can drink without stopping or messing with a flask. It comes in a few different colors and patterns. Each pattern is unisex, so there is something for everyone available. The main zippered compartment is also large enough to hold a few other small items. There are also two zippered hip pockets for more small items, like money and your keys.
The only significant complaint about this pack is that the magnet is not as strong as it could be, which causes the tubbing to come loose. This is only a minor annoyance, but it is a design flaw many of the customer reviews mentioned.
Osprey Packs Seral Lumbar Hydration Pack Key Features:
- Multiple patterns available
- 5-liter reservoir included
- Dual-zippered hip pockets
- Magnetic bite valve attachment
Who Should Buy a Hydration Pack
Hydration packs are designed to let you take a quick sip of water without slowing down or messing with a water bottle. While most people might be fine throwing a water bottle in a backpack, those who don’t have the liberty of stopping every time they want a drink will need a hydration pack. This includes hikers, runners, and cyclists. Those in competitions and on time-crunches will benefit the most from a hydration pack. However, even those who just don’t want to slow down can benefit from one of these systems.
Another big perk of a hydration pack is its space-saving nature. Hydration packs don’t take up extra room in your backpack. Instead, they often come with straps and are wearable independently. Because of this, you have more room in your backpack to put items you might need. They’re also more lightweight since they hold more than the average water bottle but are made of very light material.

Important Features to Consider
A hydration pack should do several things well. Here’s what to consider when selecting a hydration pack:
- Size. The bigger the pack, the more water it will be able to hold. How much water you’ll need will differ depending on what you’re doing. A cyclist who is gone for a few hours at a time will need less water than a hiker who is often on the trail all day. Of course, you can fill up your pack with less water to keep weight down if you’re only going somewhere for a few hours. However, you cannot fill a pack past its limit. Because of this, bigger is often better.
- Weight. Weight is significant. If a pack is hefty, it is only going to slow you down and can fatigue your shoulders and back faster. Luckily, most packs are pretty lightweight, and many weigh only a few ounces by themselves. Double-check the weight on anything you purchase, though, to ensure you aren’t getting something ridiculously heavy.
- Durability. Your pack is likely going to be put through a lot. Whether you’re hiking, running, or cycling, there are plenty of bumps and snags each hydration pack is going to experience. They must be durable enough to survive an active lifestyle. Otherwise, you could end up with a busted bag and soaking wet clothes.
- Ease of use. The point of a hydration pack is so that you can easily take a sip of water without stopping. If the bag is difficult to use, it isn’t doing its job.
- Cleaning. You will need to clean your hydration pack at some point. In some cases, this is extremely easy to do. However, some packs made it very difficult and were not designed with cleaning in mind. Look for packs that have removable bladders, as they tend to be easier to clean.
- Extra storage. Many packs included extra storage pockets for small items. Some people will find these pockets very helpful, while others won’t care much about them. It depends on your situation and personal preferences.
- Fit. If a pack doesn’t fit correctly, it will jump up and down, potentially breaking and messing with your balance. In some cases, it can even rub and create sores. Choose a back with adjustable straps so you can perfect the fit.
Frequently Asked Questions
What is a hydration pack, and how does it work?
A hydration pack is a bag with a clear bladder inside. This bladder is filled with water and connected to a tub, which has a mouthpiece on the end. When the mouthpiece is “opened” or sucked on, the water goes through the rub and into the user’s mouth. Typically, these hydration packs are carried on the back or on the hips. This allows it to be close by when the user needs a sip of water.
Can you put ice in a hydration pack?
It depends on the pack and how big the opening it. Most do have a large enough hole for you to insert ice cubes into the pack, but this isn’t true in all cases. Of course, the size of your ice cubes also matters.
Many people will fill their hydration pack up half the day before they use it and put it in the freezer. Then, when they’re ready to head out the door, they’ll remove the frozen hydration pack from the freezer and fill the rest with water. This ice will melt even slower than ice cubes because less surface area will be exposed to the warmer air and water.
Can you put Gatorade in a hydration pack?
Yes. Any liquid can go in a hydration pack. However, keep in mind that Gatorade is very sugary, which will make mold and bacteria grow faster inside the tubing and mouthpiece than usual. If you put Gatorade in your hydration pack, make sure to give it a good cleaning.
Can you put a hydration pack in a regular backpack?
Yes, but it might not be a good idea. Most hydration packs are designed to be worn alongside a regular backpack. If you put it inside your regular backpack instead, you may run into problems with leakage and tubing management. Most backpacks are not going to have an easy way to run the tubbing or a waterproof container for the hydration pack.
