HydraPak has been creating and developing performance-driven hydration systems since 2001. The company carefully considers each product they manufacture and where they can be best used when designing them. They have also partnered with big brands such as Osprey and Salomon.
They collaborate with their brand partners from design to testing, right through to the finished products. Hydrapak is leading innovation, and it engineers outdoor gear to be safe and reliable, so that you can go beyond your last milestone.
Hydrapak has a broad range of products. We’ve reviewed the Velocity™ 1.5 L, the Force™ 2 L and the HydraSleeve™ Reservoir 3 L.
Velocity™ 1.5 L
The Velocity™ 1.5-liter hydration bladder features a patented Slide-Seal™ top, a wider-than-average opening that allows for easy cleaning and quick filling. Once closed, it has a tight, leak-proof seal.
The reservoir is easy to carry, and with the Dual FlexGrip™ handle, you won’t have any issues removing this from the pack.
The bite valve is a self-closing High-flow Blaster™ bite valve. The valve switches off by twisting the on/off bar, which will also prevent leaks when it’s not in use. With Hydrapack’s Plug-N-Play™ connect system, you can remove the drink tube from the reservoir to make filling it more straightforward.
This hydration bladder also features a useful external gauge, which allows you to track the level of the bladder’s contents.
They make the product from thermoplastic polyurethanes and use RF-welded seams, which makes this a long-lasting product. The Velocity™ 1.5 L is 100 percent free of PVC and BPA.
- Capacity is 1.5 liters.
- Dimensions: 12.3 Inches x 5.9 inches.
- Weight is 4.4 ounces.
Force™ 2 L

The dirt guard prevents dust and grime from being collected in the bite valve, ensuring a safe and clean drinking experience every time.

They have designed it to be durable, so it won’t break if it’s dropped or even thrown.
The bladder has a clip buckle on the top, and when you close it, this becomes a handle that you can hang or carry the unit by. This reservoir also features a Shape-Shift™ 3L reservoir with adaptable baffles that maintain a low profile.
However, you can unlock the baffles to access the full volume of the reservoir.
They’ve designed the bite valve in a handy self-closing style and allows a high-flow water blast, which you can control using the on/off bar. This also helps prevent leaks when the hydration bladder isn’t in active use.
Refilling is no hassle, as you can easily remove the drink tube from the reservoir using HydraPak’s Plug-N-Play connection system.
The HydraSleeve™ Reservoir is waterproof and made from 210 Denier nylon ripstop fabric; the entire thing is PVC-free and BPA-free.

Founded in 1974, Osprey’s owner Mike Pfotenhauer has every product design pass through his hands before going to production. When he started his store, he had travelers and backpackers seek him out for his made-to-order and custom-fit packs.

Osprey has a diverse product range geared towards all outdoor activities, be it mountaineering, running, skiing, snowboarding, hiking, or backpacking.

MSR Dromedary – Best Hydration Bladders for Backpacking
A mountaineer and engineer by the name of Larry Penberthy founded Mountain Safety Research (MSR) in 1969. He was driven by the idea that the key to unlocking extraordinary adventures was reliable and safe equipment.
Today, MSR is still innovative and designing high-performance equipment. They use their combined knowledge of science and engineering to deliver solutions to challenges that explorers face.
MSR is also the founding member of the Outdoor Industry Association Sustainability Working Group. This is an alliance of 300 outdoor brands, manufacturers, and suppliers that are dedicated to taking on the sustainability challenge.
The MSR DromLite™ Bags come in a range of three sizes: the four-liter, the six-liter, and 10-liter Dromedary Bags. These long-lasting and durable bags fold into a remarkably small size — roughly the same size as their cap. These hydration bladders, Made from polyurethane, with RF-Welded seams, are incredibly durable and can also withstand freezing temperatures.
They feature a loop that makes the reservoir easy to hang or carry, and it comes with useful accessories such as the Svelte 3-in-1 cap. This lets you pour, drink, and fill with ease. These hydration bladders are BPA-free, making them extra safe to drink from.

You can add to your MSR DromLite™ bags by buying an easy-to-use kit that will turn your standard hydration bag into a hands-free hydration bag. The kit includes a bite valve, a shutoff valve, a custom hydration cap and a taste-free drinking tube.
MSR uses the knowledge they have acquired over the last 50 or so years to develop clean drinking and water sanitation for communities around the world.
They produce some of the safest, reliable, high-performance and environmentally friendly adventure products on the market. Some of this technology and knowledge has also gone into their hydration bladders.
This company was born out of thirst, literally. The founder, Michael Edison, entered a race called “Hotter N Hell” in Wichita Falls, Texas. The race was a 100-mile course with very few water stops along the way.
Michael was an emergency medical technician, and for the race, he filled an IV bag with water, put that into a tube sock, and then clamped the thin hose to his shirt with a clothes peg.
At first, the other contestants laughed at him, but then they saw that he could cycle further with fewer stops. And so, the first hands-free hydration bladder was born.
CamelBak has the CRUX™ Reservoir, which comes in three sizes and also has a Lumbar Reservoir option. The CRUX™ Reservoirs share many features, and, regardless of their size, they have all received a recent face-lift to keep up with industry standards.
They make the CRUX™ Reservoir from polyurethane, and it has Hydroguard™ applied science that prevents the growth of bacteria in the tube and reservoir. The Big Bite Valve now offers 20 percent more water flow and also self-seals after each sip.
The CRUX™ Reservoir has the Quick Link System that lets you easily disconnect the tube and remove the hydration bladder from your backpack. While you are going about your activities, the reservoir baffles provide a low profile and minimize any sloshing.
It has a nifty on/off valve, which allows you to seal the tube with ease, using one hand. It also has a sizable access port, which makes it easy to fill and clean. These hydration bladders are 100 percent free of BPF, BPS and BPA’s.
- The dimensions of the 1.5-liter are 12 inches x 7 inches x 2.5 inches.

You can also purchase the cleaning kit for a thorough cleaning, which you should do to preserve your product’s life.
One of CamelBak’s aspirations is to eliminate disposable plastic. They’re dedicated to environmental sustainability and have manufactured their products to be durable so that they can help reduce plastic waste. They are also major suppliers to the U.S. military and worldwide law enforcement agencies.
Choosing The Best Hydration Bladder For You
Whether you’re an intrepid adventurer or simply an outdoor activities enthusiast, then the convenience of the hydration bladder will appeal to you. Whatever your activity, be it hiking, cycling or running trails, you will need to have a water supply with you.
The amount of water you consume during your activity will depend on several factors:
- The particular activity you are doing.
- The duration of the activity.
- Temperatures on the day.
Hydration bladders have options for different activities, so you can always choose one that fits your requirements.
When you are considering buying a hydration bladder, it’s important to keep in mind the activity you will be doing. For example, if you are going to be doing short walks through the city park, then a 1.5-liter bladder would be perfectly adequate.
If you’re cycling for long distances, then you may want to get the Lumbar two-liter. These are more commonly bought by climbers, cyclists, skiers, backpackers and snowboarders, as it offers an outstanding balance between weight and water capacity.
If your activity is long distance and well away from clean water, then looking at the hydration bladders that are three liters or more would be the best option for you.
The higher water capacity is beneficial if you’re going extreme distances. The reservoir would most likely be heavier, but you don’t have to always fill it to the top if weight is a concern.
You want to choose a hydration bladder that can take a beating while remaining durable, sturdy, and leak-free. The material should be long-lasting, robust and flexible. You don’t want to get snagged on a tree or shrub and have it puncture.
You also want a product that will handle consistent use in all weather. See if you can purchase accessories that are winterized, such as insulated tubes, insulated sleeves, bite valve covers and even reservoir covers to keep your product from cracking or malfunctioning in the cold.
They may add a little more weight, but they can make a difference to your activity, and the durability of your hydration bladder. Nobody wants to be replacing equipment too often.
Considering you’ll be putting this product in your mouth, make sure it states that it’s lead-free, phthalate-free, PVC-free and BPF, BPS and BPA-free.
Companies are leaning towards sustainability, and they now design many products to last longer to prevent waste. Most offer a warranty that will cover any defects in manufacturing.
Ease of Use
Hydration bladders free up your hands while you are climbing mountains, cycling or running. They offer the convenience of staying hydrated easily while being on the go.
To make them even more convenient, you can purchase accessories like magnet clips, which allow you to attach your hose to your sternum. This makes it easier to access the hose to sip from.
You can also change nozzles if you prefer a self-sealing bite nozzle instead of the type that you need to turn to switch on and off.
A hydration bladder should be easy to fill. You don’t want one where you have to fight the faucet to get water inside it.
New version hydration bladders either use a screw cap lid or a Zip Slide lock. These are uncomplicated and make it easy to fill the bladder with water.
If you’re purchasing a new backpack, bag, or sleeve, make sure it’s the right dimensions to fit your hydration bladder when it’s filled.
Not all bags are compatible with all bladders, and you don’t want to have to buy a new bladder because your current one doesn’t fit in your new backpack.
Once you’ve chosen the pack you want, slip your bladder into it, and you are good-to-go on your adventure.
The HydraSleeve™ Reservoir is our selection for the Best Overall Hydration Bladder. It offers so much versatility and durability.
When the call for adventure comes, you want to know that you can use your hydration bladder in any environment and it will handle enough liquid to get you to the end.
After committing to using a hydration bladder and then picking the bladder that best fits your needs and activities, you will never look back.
