I love the Down Shift Pack
I bought this pack for mountain biking. I am very happy with how comfortable it is to wear on rides. It does keep my water cool. I appreciate the quality of the closure on the bladder.

Awesome Backpack!
I just bought this and used it for the first time last weekend for a ski trip. This pack is sleek, the straps adjust easily, and it holds an ample amount of water for a day trip. Perfect for holding extra layers, snacks or whatever you may need. Great fit on my back and shoulders, I almost forgot I was wearing it.

Lives up to the hype!
I don’t typically review anything but this hydration pack is AMAZING!
Was able to have enough COLD water to hike 8+ miles at Zion National. The curved design helped to keep my back cool and the size was big enough to even keep my other camera lense.

Comfortable fit and keeps water ice cold!
After thinking about it for a long time I purchased this about one month ago and am so happy I decided to finally do it! I live in AZ where late summer is still very hot when hiking. I leave work and fill it up with ice water, hike 2-3 miles and still have ice in my pack when I'm done. Love, love, love this backpack! It has a comfortable fit and does not weigh me down. Great purchase!

Game Changer!
Honestly this pack has been a total game changer! Though most seem to use it for biking, I've been using it for EVERYTHING this summer - biking, canoeing, hiking, etc. It's been a great hands-free way to stay hydrated and it's so comfy you almost forget that you're wearing it. I also get complements all the time. The pockets are also great for your phone, keys, ID, SNACKS - it's all you need!

Best MTB backpack I've ever used
I typically hate wearing backpacks while biking. They are uncomfortable, sweating, and lack the proper storage for bike knick knacks. At least until now. The Hydro Flask backpack is one of the best. The water loads in the bottom, so the weight comfortably sits lower than your typically hydration pack, with better than average lumbar comfortability. I've recommended this to a few folks, and they also agree it's better than any other bike backpack.
It's great for long rides, when you need a lot of water, snacks, and gear to get you through the ride. If I could give this more than 5 stars, I would.

Everything you want in a bike backpack.
Before I wasn't the biggest fan of biking with a backpack but Hydroflask really outdid themselves with this pack.
The fit is nice and snug, the straps are a bit too long, but that can be fixed.
Once tightened down the pack sits nicely on the back and hardly moves even when ripping through nasty rock gardens are hitting the jump line on tiddlywinks.
Also, there's not a whole lot of non sense and flare to the pack. everything has a purpose and I love how big the front pocket is!
I love being able to keep my water ice cold especially on those hot summer days. the whole hydration system is perfect too! Really top notch!

GREAT pack for multi-use.
I wanted to test this pack a few times before reviewing but can now say it has passed the adventure trail test! :) My favorite aspect of this pack is the weightless feeling I had on the trail. It fits my frame perfectly (and straps can be adjusted) and snugs right up to my back. There was no jostling or shifting when I was hiking or jogging. I know it's made for biking, which it works well for - but don't be afraid to pack it on a long day hike! It was brilliant. The water stays ice cold and there is plenty of room for a packed lunch and other trail necessities. To be honest, I am usually NOT a fan of ANY hiking or running pack so I was blown away by how much I love the comfort and feel of this bag. One more thing - the small front pouch is fleece lined which is perfect for your phone (for the camera) and/or sunglasses! Big love for this new product.

Love this product.
We used this for hiking instead of biking and loved how cold it kept the water. My son used it and he said that that loved that it cooled his back on a very hot hike. The water was still super cold 6 hrs later and had chunks of ice in it so it worked very well. We absolutely love this pack and he asks to take it when it’s hot outside.

Most thought out Hydration pack
My family and I are always adventuring out into the wild. We have been accustomed to carrying a regular Hydroflask bottle in a backpack to keep things cold. Now we opt for the Downshift pack for any outing requiring hydration. It makes it that much easier to stay hydrated while on the go. The amount of storage for such a slim pack blew us away! We usually shove a pack towel or change of clothes for our 5yr old in the bottom under the reservoir and fill the top with snacks and maybe some camera gear. He mesh arch in the back helps prevent getting really sweaty and keeps airflow happening. The outer lined pocket is perfect for sunglasses or gummy bears. As a professional bike racer this bag goes with me on longer rides where I know water will not be available and heat is an issue. From someone that has owned every camelback since the beginning, the Hydroflask Downshift Pack is worlds above in function and keeping things cold.

Would this work in cold weather for activities like snowboarding or skiing?
We apologize for the delayed response.
It can work in cold weather activities but as it is water inside, there is a chance that the water could freeze.

Can you use this to go to music festivals or is it too bulky? Are you guys going to make a smaller condensed version?
We apologize for the delayed response.
The hydration pack should work to go to a music festival. Its not bulky and its easy to carry around even when the bladder inside is full of liquid.
Your suggestion of a smaller condensed version will be passed along to the appropriate department.

Is there room for one or two extra water bottles to fit? I always like to bring extra water just in case.
No

How is this for someone who runs half and full marathons? Is it bouncy at all? How is the mouth piece? Is it easy and comfortable to get to the mouthpiece while running and put it back out of the way?Is it easy to quickly grab a snack w/o taking off pack?
I apologize for the issue you are having. Please contact customer service at 888-584-9376 to discuss this further.

I understand the concept of this, but how do you clean the 2L container inside the backpack, is it removable? Seems to me that like all water bottles I’ve had, they get that black funk on the lids/rims, that make it hard to clean, end up in the garbage.
I have one in blue and yes it is fully removable and easy to clean i remove the pouch that holds the water as well as the tube or "straw" love mine perfect size and unlike others it keeps your water cold for hours
