Lesser Fill


The Hydrapak Shape Shift comes in two different size choices depending on how much hydration you need. If you find you are not going to be active for long or that you just don't need as much water with you they off a 2-liter version. If you find you are the opposite and are needing more hydration than a 2 liter can offer they also make a 3-liter version for your needs. This particular model does not come in any bigger sizes due to the fact that it would cease to be low profile when it becomes any larger.

Keep in mind these sizes are not ideal for a full family or group but are perfect for a singular person. If you are wanting to hydrate a whole family or group other brands sell larger options up to 10L or alternatively you could have a couple of different people carrying 3L hydration reservoirs.

One of the only downsides to this product is that the advertised amount of 3 liters or 2 liters is not 100% accurate. While they both do hold that much liquid if you fill them to that amount you will be unable to close them. Which for most people defeats the purpose of the product. The advertised 3 liters holds 2.5 liters when closed and the 2 liter holds 1.5 liters when closed.


Cleaning the Hydrapak Shape Shift is a lot easier than you would think. It has a removable baffle that is capable of locking and unlocking. When it's unlocked it serves for an easier cleaning experience. You have two options to choose from when cleaning the reservoir, you can either rise it in the sink with soapy warm water or just easily throw it on the top rack of the dishwasher to clean and completely sterilize it.
To clean the tube and bite valve is pretty simple. If you only are storing water in your hydration pack then a simple rinse will do, for a deep cleaning and to make sure bacteria is not breeding you can simply store it in the freezer to sanitize the whole unit. If you are hydrating with anything other than water you are going to want to take some different cleaning steps. You will want to dismantle all of the removable pieces and soak them all in soapy water. To clean the tube properly you will want to use the Hydrapak tube brush that's specifically made for cleaning your tube, this piece is sold separately but if you hydrate with anything other than water its an essential.
Before you place it away for storage make sure everything has air dried thoroughly. If you don't you could be susceptible to mold or bacteria growth. Which for something you drink out of is less than ideal.


You will be happy to hear all the materials used in this hydration bladder are 100% BPA and PVC free. They keep your health in mind when they designed these products so you would not have any chemicals leaching into your water. Being health conscious is huge for some customers so you can keep your mind at ease knowing you will be able to get healthy chemical-free hydration from this hydration bladder.
They make the reservoir out of TPU which is safe and non-toxic, not only that but it can also expand 8x its size. This means if you want to freeze liquid in it you are completely safe to do so without risk of tearing or bursting your reservoir.
The other materials in the bag such as the tube and bite value are made out of HDPE which is a form of plastic and silicone.


Because this product is advertised as being low profile is also pretty lightweight as well. It's all thanks to the TPU they use for the reservoir. Depending on what size you get they vary slightly in weight but not by much. The 2 liter is 135 grams or 4.7 ounces, and the 3 liter is 154 grams or 5.4 ounces. This makes them pretty amazingly lightweight and easy to carry. You won't feel much more than the weight of the water once you have them filled and in your pack. When you have finished your whole reservoir it won't add any unwanted weight to your pack which is exactly what most people want.


When Hydrapak made this hydration reservoir they made it specifically for people who do high impact sports like running, skiing, snowboarding, and mountain biking. This means they had to try and make it as durable as possible to keep up with you and your lifestyle. Most customers that reviewed it found that they didn't have any issues with the durability and in fact found it to be quite reliable and hearty.

On the other hand, there were a few reviewers that either had a leak spring instantly the second they filled the product up for the first time or they had one happen overtime. Thankfully Hydrapak offers a beyond lifetime warranty on all of their products. If you have any manufacturing defects or failures at all throughout having your product they will replace or repair your item for free. With a warranty like that there is really nothing to lose.


What Hydrapak has done to try and make them stand out from the rest of the hydration bladder world is they created a system the call plug-n-play. Basically what it is is a way to easily disconnect the drinking tube from the reservoir pack without leaking everywhere. One you disconnect the drinking tube an auto shutoff valve will prevent any leaking so you can make refills easy and mess free. This is great if you are on the go and don't want to make a mess around and all over you, as well as great just for the person that needs to get out of the house quickly and just needs a refill on their hydration pack.


Unlike most baffles on hydration bladders, this one has a unique feature where the baffle actually unlocks so you can hold more water within it compared to a unit where the baffle did not unlock. Locking the baffle is key when you want a low profile and increased stability during high impact movement.

If you just want to be able to carry more water and don't care about stability or are done with the high impact portion of your activity you can easily unlock the baffle. This is also key because the baffle doesn't hinder the reversibility of the bag like it would on most other products.


The maintenance required for this hydration pack is quite minimal. As long as you are taking care of it by cleaning it properly and thoroughly it should last you through every activity you take it. It’s key to remember that after you wash all the parts to make sure they need to all be able to air dry thoroughly. If they do not get the proper airflow they need and moisture gets trapped it's going to leave it susceptible and vulnerable to molding or any other bacteria growth that thrives off of moisture. When this is something you will be drinking out of you are really going to want to make sure you keep it as clean and germ-free as possible to avoid getting sick.


One of the best parts about the Hydrapak Shape Shift by far is the beyond lifetime guarantee that they give to all of their products. If you ever buy anything from Hydrapak it will come with this warranty guarantee. What the guarantee covers are if your product has any failures due to the materials or manufacturing process that they will either replace or repair your item for free. This gives you great peace of mind when purchasing a product so you know they even if you get a manufacturing defect they will always make it right for you. What id does not cover however is if you damaged your product due to misuse or user error, so try and be as careful as you can.


This hydration bladder has so many advantages it's hard to know where to start. It comes in two different sizes depending on what size fits your needs the most. Its BPA and PVC free so you can keep yourself healthy and out of risk of leaching chemicals into your water. Has an adjustable baffle that you can keep closed for a low profile and higher stability for high impact sports or can keep open to hold more liquids when you need to. It has a high flow design that makes sure your water gets to you 20% faster than most other hydration tubes.

It is reversible making it easy to clean and easy to airdry. Has their special plug-n-play system that allows you to detach the drinking tube for easier fill-ups while an auto shut valve automatically gets put in place once you detach it making for less of a mess. Best of all it has a beyond lifetime warranty on all of the products they sell so you never have to take a gamble.


Overall there aren't too many disadvantages to speak of. The biggest one that reviewers were writing about was that the Hydrapak Shape Shift they got were immediately leaking. While this is incredibly disappointing to have happen when you first open a new item up they do offer a beyond lifetime warranty on all of their products. This means that even if you do happen to get a faulty product by accident they will replace or repair it completely for free. The only other thing that left customers a bit disappointed was that the advertised size is not actually as much it can hold while closed. Both of the sizes can only be filled .5 liters less when closed. While it is stated on the packaging of the product it’s not very apparent when purchasing online.

Bottom Line

Most people who bought the Hydrapak Shape Shift loved it and continue to use it to this day. Because of their spectacular warranty, you really don't have anything to lose if you are hesitant about purchasing. This hydration bladder is great for high impact activities such as running, skiing, snowboarding, and mountain biking. Which also means its durable and will withstand what you put it through. It’s loaded with mechanics that are there to make your life easier, like the plug-n-play feature that keeps you and your surroundings dry while filling up.
The fact that its low profile and has a sealable baffle means that even when you are moving as hard as you can you won't notice your hydration bladder moving. This is great for a solo trip or for staring between two depending on how much hydration you both will need. It's easy to slip in a bag and have hydration easily at your convenience. Overall this is a great buy at a great value that is sure to last you a very long time.
