Top Pick Award

Our Verdict

If you're looking for the hands-down best option for ounce-counting adventures, the Hydrapak Shape-Shift Reservoir is for you. It has a simple design and slim profile, making it race-ready and compatible with any running or hiking pack. The zip-lock divider prevents water from sloshing around, while the flip top opening makes for easy cleaning and fill-ups. The blaster valve delivers water quickly with little suckage required, and the quantum clip keeps the tube in place. It fits comfortably into packs of all sizes but might need a little bit of work to wiggle into place when the pack is full.

This bladder withstood freezing and laying out in the sun. It has a very similar construct to the Geigerrig Hydration Engine, our Editors' Choice winner except it is not pressurized. Flip it inside out and throw it in the dishwasher for a good clean. While it doesn't have as burly a construct as the CamelBak Crux, it is surprisingly durable. This is a simple and easy-to-use system, winning a Top Pick for minimalist escapades.

To ensure a thorough clean now and then, use a HydraPak Tube Brush. For an extra squeaky clean bladder, throw a tablet like Hydrapak Bottle Bright in there to get rid of any odors and stains.

Our Analysis and Test Results

Share:
HydraPak is becoming a powerhouse in the hydration world. This brand builds high-quality hydration bladders used by several brand partners, including Osprey, Innov, Geigerigg, Gregory, Salomon, Nathan, The North Face, Patagonia, GU, and many more. The bladders are built with a strong polymer, different than any other bladder we've tested. Most are also dishwasher safe.

Performance Comparison


This award winner is slim, simple, and light. This race ready bladder is a great addition to your gear list on any mission - especially when weight is a significant consideration.

A look at the new make-over of the HydraPak Shape-Shifter.  It's a lightweight contender that wins a Top Pick for all who are looking to carry as little as possible.

Ease of Use


This bladder features a simple "blaster" bite valve that allows sufficient flow with little suckage. The locking mechanism on the bite valve can be difficult to use and did lock up during our testing; we attribute this primarily to using sugary drinks in the bladder and not cleaning it properly. If you're in the market to switch it out, you can use any of the other brands with a quick release mechanism.


It features a thin profile and a ziplock divider inside to prevent sloshing while on the move. Zipping up this divider makes the profile thinner while unzipping it makes it larger. It fits nicely into narrow bladder sleeves and is compatible with most packs. We love the quantum magnetic clip that keeps the tube in place. This helps to prevent the mouthpiece from jostling around on the go.


The bladder also features a hanger, like other bladders, which helps to keep it upright in the back. By attaching this, it won't collapse under pressure, ensuring that you can suck every last drop of water that is left in your bladder. Overall, this is a simple and easy-to-use option for all types of outdoor activities.

Our main tester is PSYCHED about the lightweight design of this bladder while crushing over 6 000ft of vertical gain in the steep mountains of Colorado. She especially appreciates how it fits nicely into her running vest.

Ease of Care


With a wide mouth opening that is absolutely bomber and its ability to turn inside out, this is one of the easiest bladders to care for. A brush easily fits inside for a heftier clean. Drying is also a cinch. Simply unzip the internal divider, pull it through, and let it dry. In addition, the bite valve and hose are easily removed for cleaning. Just put the valve in a hot bath to clean out any unwanted bacterial build-up. Then clean the hose with the HydraPak Tube Brush.


The best maintenance is daily maintenance. Make sure to rinse and dry this bladder after every use to avoid bacterial growth. It can also handle being thrown into the freezer to ensure any bacteria is killed. Overall, this is an easy bladder to take care of, especially if you rinse and dry it after each use.


Even though this system is easy to care for, you must take a few extra steps for long-term durability. Like the Geigerrig bladder, make sure to lubricate the O-rings occasionally to ensure the quick-release system continues to work over time. Our main tester had a similar pack with the exact quick release system that failed due to a lack of care. That said, it's good to do this with all quick release systems.

Ease of Filling


Fill this bladder in a slow trickling stream, a river, a lake, or from your tap at home. Merely open the bladder, pinch the sides, and filling can begin. The flip-top design promotes easy collection from a slow-drizzle. Lay it down flat and start your water collection.


The only place you might have difficulty filling this bladder is in a shallow basin like a water fountain. It does not have a built-in handle, and the body of the bladder is not rigid, making it hard to hold in place. Aside from that, its largemouth opening is great to fill up from most sources with ease.


Quality


While the material is a thinner TPU film than other contenders, it's still fairly durable. It's not as resilient as thicker-filmed products like the Camelbak Crux.


The bladder is 100% welded with minimal seams that we couldn't pull apart. We are happy to report this bag can stand up to freezing and being filled with warm (not hot) beverages. Overall, a good quality bag that is not as resistant to punctures as thicker-plastic contenders.

Weight and Packability


This is a super lightweight bladder. At only 4.85oz (for a 3L bag), it hardly feels like you're carrying anything at all! Many of our testers choose this bladder when seeking a companion for running a race or while going ultralight. It is our favorite for long distance running. As a result of this lightweight and simple design, it earned itself our Top Pick for this exact purpose.


When the bladder is empty, and the hoses are disconnected (at the base), it can roll up into a tiny neat package. This promotes easy storage in a backpack or the freezer (to kill bacteria) when not in use. Overall, one of the lightest and simplest hydration bladders on the market.


Best Application


While it functions well for lightweight missions, its functions are not restricted to just that. Take it will trail running, biking across the county, or just day hiking with the pup. It's a great option for most applications. Don't plan on throwing it around camp as the exterior material isn't as durable as other contenders.

Running through the Peruvian Andes wasn't easy but having a light bladder like the HydraPak Shape-Shift made the experience so much more enjoyable!

Value


At only $35, this is one heck of a deal. A simple, lightweight bladder for a great low price. We suspect it will last you years with proper care. If it weren't a top pick, it'd be a contender for our Best Buy Award.

Conclusion


This race-ready bladder is lightweight and featureless. It truly excels where a lightweight design is required. Take home this Top Pick for all your speedy adventures this year!
