KUYOU Hydration Pack,Hydration Backpack with 2L Hydration Bladder Lightweight Insulation Water Pack for Running Hiking Riding Camping Cycling Climbing Fits Men & Women

This item is ALL ABOUT THE BACKPACK ITSELF!! I tossed the bladder because it makes the water taste like plastic (which I figured it would) and I use only the backpack with my Deuter Streamer bladder. The Deuter Streamer water bladder is the BEST bladder on the market having no plastic taste or chemical taste! ALL OTHERS HAVE A CHEMCICAL TASTE -- ALL OF THEM! Only Deuters has zero weird taste! This backpack has an enclosed zippered compartment for a bladder. I'm using the Deuter Streamer 2 liter bladder, but it can easily fit the 3 liter -- easily! There is an extra compartment for you to place other things and that compartment is huge! The ends of both straps have a loop so you can put the bladder hose tip through one of the loops to help keep the hose out of your way while you hike or cycle. This backpack is easy to use and adjust. It sits close to the body making it comfy and you don't feel as though you are carrying something heavy. The price is fantastic especially for everything you are getting and I dare you to find the same elsewhere. I just bought a second one. Highly recommend it for quality and hydration capacity!

Love this backpack works wonders, it fits 2.5 16oz water bottles. Also has a hidden pocket for your wallet and keys and room for hiking snacks plus a mesh side for extra waterbottle. Its comfortable and adjustable. Also very lightweight, great for hiking and keeping me hydrated

I spent a long time searching for a hydration pack at a decent price which had an insulated pocket, a cover for the mouthpiece, and an opening in the bladder large enough to put my hand through for easy cleaning. This one had it all and I thought it was super cute to boot. However, I used it four or five times and it leaked every time. The hose connects by pushing a button on the bladder valve, seating the hose, and releasing the button to lock the hose in place. I gave the hose a firm tug each time and checked the button was completely released every time I used it. The bladder valve has a safety feature wherein water will not leak out of the valve if the hose is not connected. What kept happening to me, however, was that the button would get pressed and the hose would partially disconnect, but not completely. I'm not sure how the button was even getting pressed in the first place because I never stored anything else in the bag and I never leaned my back against anything. The bladder fits snugly enough within its insulated pouch that the hose wouldn't completely unseat but was in far enough that the valve connection would drip and soak through the bottom of the backpack. I bought a different backpack whose bladder had a threaded hose connection, and planned to return this one, however the other bag was horrible so I've returned that one and purchased its awesome nonleaking bladder to use in this bag instead. Trying the other backpack helped me realize why this backpack is so awesome, even though the bladder isn't. The back is only partially padded, which means that there are channels where the bag is not pressed against you. (The other backpack I tried was evenly padded, and although it was half the size of this one, I soaked through multiple layers of clothing immediately.) Also, having a zippered compartment separate from the main body of the bag is great for storing small things separate from big things (like my keys versus an extra shirt). This makes it easy to swing the bag around while riding and rummage in one pocket or the other without worrying about tugging out my shirt and throwing my keys or other items overboard in the process. Wish I could've saved some money and purchased the backpack without paying for a bladder I will never use, but that's life.

Works for ppl are on the go

Just the right size for a day pack. Only niggle is that the zipper for the insulated water compartment is in the middle instead of more towards the top. So getting the water bag inside can be a little tricky. It's not a big deal, and I've used this hiking, biking, and motorcycling. Works great.
