  • 20 L Hydration Pack is rated 4.7 out of 5 by 25.
    Rated 5 out of 5 by from Best adventure backpack ever!!! I love this bag so much. I am a zipline guide so I need to drink a ton of water during work. It’s absolutely amazing have ice cold water on me when sometimes I’m zip lining for about 5 hours at a time. The bag will actually keep water icy cold for about 13 hours if you fill it halfway with ice, but it will accurately keep ice and cold water for about 4 hours if you fill it to the recommended amount which is about. Quarter full. This bag is amazing and has a very spacious secondary pocket which is definitely enough for me on adventures.

    Rated 5 out of 5 by from Awesome quality This is a high quality hydration pack. I have been using it for everything. It holds a big amount of water that I don’t run out at all. It fits comfortably on my back as well. It’s super easy to clean out as well.

    Rated 5 out of 5 by from Works great I am an avid hiker and also runner so staying hydrated is extremely important. Sometimes just having a small bottle of water doesn’t help nor does it stay cold. I was able to get this hydration pack a try and I’m so glad that I did. It holds 2 L of water and also stays cold just like the instructions say it does. It is also very comfortable and wasn’t too heavy like I thought it would be.

    Rated 5 out of 5 by from Excellent feature! I love my new Hydro Flask Hydration Back pack! This back pack it’s easy to use, inside it cames with the water bag up to 20 liters with the large valve that let you use while you are doing your activities! This pack have a Cold Flow system with an insulated reservoir that keep your water cold for more than 4 hours. The design is ergonomic and comfortable for any sport or situation, the shoulders and hip straps are adjustable. The pack fabric it’s water proof and have two separate compartments, one for the liquid bag and the other to use for your stuff. Simply amazing with all the features in one! Even my 5 years old daughter can use it. She love it and I too!

    Rated 5 out of 5 by from cool and functional! I have been so excited to use this hydration pack! I am an avid hiker and this was perfect for a long day at the trail. The pack is lightweight, stylish, and fun to use! It is easy to add water and it did not leak after multiple uses.

    Rated 5 out of 5 by from Keeps me hydrated! I really like having this hydration pack because it holds 20 L of water. I love taking it with me when I go hiking. It has a straw like drinking mouth piece to drink the water from the bag. It holds liquid well and doesn't leak at all. Definitely great to have to stay hydrated.

    Rated 5 out of 5 by from "Smart Tech Hydration" Well family camping time and I decided to try my 20 L Hydration Pack by Journey. My family and I go hiking a lot and this was a definite need for this occasion. This smart tech Hydration Pack weighs about 3.6lbs. and comes with a lifetime warranty. Also have 4 pockets 2 inside, and 2 outside. Made with waterproof fabric, puncture and tear free. Adjustable straps, and a self sealing valve. Definately recommended for day trips up the mountain.

    Rated 5 out of 5 by from LOVE THIS PACK!!! I love this hydration pack!! The quality of this pack is stunning! It holds 20 liters but yet is still nice and compact! The bladder is high quality and is easy to fill and wash! The actual backpack is of super quality, the straps are well made and comfortable to wear! It is also important that we are able to easily clean the inside and the outside of this pack! Overall superb quality and an excellent product!

    Rated 5 out of 5 by from Great Hydration Pack We work in the city of Pittsburgh several times a week and this is actually when I gave this a try and put it to use. This was amazing!! I normally haul 2 water bottles with me which was super inconvenient but it had to be done because I am out all day. This made it so easy that I didn't have to stop and dig my water bottle out of my bag - just walked and hydrated at the same time! It held the perfect amount of water for me and is so simple to use. It also kept the water cool all day long on a 70* day. The waterpack is easy to fill and put back into its insulated pocket leaving plenty of room in the bag for my folders and binder as well as other work things I need. I really love this bag and I cant wait to use it when we hike. I highly recommend this and will be a purchaser for life!

    Rated 5 out of 5 by from Great sturdy and well designed backpack I like this hydro flask 20L backpack a lot, as it is very thoughtfully designed. It's very sturdy. All of its seams are well stiched/built - so you don't get any weird rips/tears/puncture anywhere. It's well insulated, not just the reservoir, but the interior pack sleeve where it sits. it keeps the water cool for almost whole day. The bag is big enough to contain lot of other stuff in it (clothes, tools, snacks etc.) when you go hiking/biking. the straps are comfortable and sturdy, so unless it's heavy - it's not a bother / tiresome on you. there is a good airflow system in the back of the materials, that lets the air flow / vent well between your back and the back of the backpack. so it doesn't get sweaty. the material is also sweat proof, so helps keep the material in good shape for long.

    Rated 5 out of 5 by from Great features! My husband and I went hiking today in the mountains and there was enough water for both of us to enjoy on the hike! It isn’t heavy which is a big deal when you have to carry something on your back! There are so many pockets and storage! It kept the water ice cold and it tasted so fresh! I love that the valve self sealed so it didn’t leak anywhere! 5 stars!

    Rated 5 out of 5 by from Great Hydration Pack This is a fabulous pack for long distance running. As far as storage, this has a lot of pockets! Overall, I could see this being a great hydration pack for long distance running. I highly recommend to all!

    Rated 5 out of 5 by from Hydrate made easy Icy cold water that will last 4 hours. I went hiking yesterday with my wife. We had enough water for the both of us and it kept us hydrate. Valve self-seals after each sip makes it easy to drink. Extra pockets come out handy to store extra stuff for a hands free experience.

    Rated 5 out of 5 by from Love it sweat proof reservoir helps to maintain cold water temperature keeps water cold for over 4 hours. Keeps heat out and cold back in. Designed to maintain cold water for more than four hours its amazing when your on a long hike or out for hours doing things. Pockets and compartments give a spot to store phone, wallet, and keys.

    Rated 5 out of 5 by from 20 L Hydration Pack My 20 L Hydration Pack keeps my water ice cold. I use it when I work outside, this will come in handy on very hot days. Has a hose that despences the water. And insulated backpack keep it cold I give it five stars.

    Rated 5 out of 5 by from Awesomeness in one package Got to try the 20 L Hydration Pack and I’m totally blown away! Took it on a bike and hike trip today and it was great,I didn’t have to worry about loosing my water and I was hands free to keep on going, just strapped it on and away I went, and I had plenty of cold water for my friends too, couldn’t ask for anything more, in my own opinion if you are an outdoors person and want a very convenient and easy way to stay hydrated get one for yourself, you will not be disappointed in having longer cold water and your hands free.

    Rated 5 out of 5 by from Pleasantly surprised Just doing the transition into this new bag and was surprised at how well it handles all of my gear with room for more. Lighter weight then my old pack and easy to set up, comfortable and bonus the bladder connects straight to the water filter. Looking forward to getting it dirty.

    Rated 5 out of 5 by from At $200 it should carry 20L or water not 3L Very overpriced! Lots of better options out there.

  • If you wanted to store can drinks with ice instead of the hydration bladder, could you?

    I have been using my pack for 4 weeks now and I already got a hole in the bottom. Is this covered by the warranty?

    Would love to know how to get your products in exchange for providing a review of the product! It seems many that received theirs in exchange couldn’t even be bothered to make sure they got the specifications correct (ie: bladder holds 20L).
