KUYOU Running Hydration Vest - Lightweight Insulated Hydration Backpack with 2L Water Bladder, Adjustable Chest Straps and Reflective Water Backpack for Trail Running Marathon Race Hiking Cycling

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!

Great pack! I thought it wouldn't fit my Platypus at first, but it stretched just enough to work now. Great size, fit and value.

Fits great, don’t hardly feel that it’s on. Carries a lot of water. Wish it had a zipper pocket to put credit card, money, keys in while you ride your bike.

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

My son used this over the last couple summers when he worked detassling corn. It works great. It holds a good amount of water and keeps it pretty cool.

I wore this to Anthrocon as a fursuiter (Like a mascot, but the costume is designed to a certain character and it is tailored specifically to one body and you can only give and take so much height/weight). Given how much a fursuit can make people sweat and dehydrate, I was not expecting much. My expectations were exceeded. It fits super well around my back, the hose was plenty long for reaching into my movable jaw (I could also have stuck it in my costume's mane). It did not leak and my fursuit's mouth was kept dry. (Due to the construction of a fursuit, the character's mouth is directly where your mouth would be). It has a decent amount of storage space, which was super useful for when I went to the Dealer's Den (it even held an unwrapped large t-shirt). It should be more than enough to store your wallet and cellphone and keys. Since fursuiters sweat a lot (as in when you wring the under armour into clear water, it looks like someone took a leak), this was vital. Especially when you have to drink every 15 minutes.The pouch stored plenty of water and it never reached the bottom (albeit it came really close one day due to an outdoor fursuit parade). Without this thing, I would have stopped sweating, and in a fursuit, that spells HEAT EXHAUSTION. Thanks to this thing, I only needed to take off my costume's head once or twice, although I did stop in the headless lounge about 8 times to make sure that I could catch my breath and slow down the sweating (But it MINIMALIZED the number of trips as I was very hydrated). Another thing I was very surprised by was that this thing did not weigh nearly as much as I thought it would. Granted, I was wearing a fursuit, so it was not nearly as noticable for me as it might be for some other people (My fursuit added about 15 lbs to me). The only complaints I do have at the moment is that it did not look too good on the back due to how the water drops down. (But I can't change that without asking for gravity to totally screw up life as we know it.) Also, one of the straps did come undone, but it took less than 2 minutes to fix and get back to fursuiting with no further problems.I was slightly angry that the hose only works if I bite at the bottom of the rubbercover. Nonetheless, this was a worthy purchase. Wearing a fursuit is not an easy task, but this made it so much easier for me. It kept me well hydrated, did not run out, and this is with 15 lbs extra covering my entire body. (Oh, and did I mention I would be wearing my fursuit for 12+ hours most of the time? And how badly you need water in there?) I am more than certain that if it worked perfectly for a fursuiter, it will work for you. I could not recommend this enough. This was worth more than the $15 I paid and I will happily recommend this to anyone who needs a water bladder/backpack. I will upload photos for context soon.

The bag is nice, but the water bladder that comes with it (at least mine) was defective and started to leak everywhere. I bought a different water bladder, and it holds it nice. The “backpack” portion has some nice room for earbuds, snacks, first aid supplies ETC. would recommend, but make sure you test the bag first.

I was talked into doing a Spartan race in January and needed a hydration pack. I found this one and liked it so much I got 2. I added one to my cart and thought I removed it or saved for later - turns out I didn’t and I ordered two ! Anyways, it holds 2L and the water pack itself seems very sturdy. The straw suction part has an on and off position, so that was helpful. There was room for a small wallet, keys and my phone in the zipper and the durability of the pouch is also great. It was very comfortable to wear throughout the race and I didn’t feel it too heavy or anything. Definitely happy with this purchase. I also liked that it came with instructions on how to get rid of the plastic smell/taste from the water pack - I wouldn’t have thought to put lemon juice with some warm water and let it sit Great buy for the value and quality !

After wearing the product only twice, on the first attempt it leaked very badly which I found I could just about stop by what seemed like over tightening cap. Also the valve for drinking was very difficult to get any water out of. Two of my friends purchased the same item, but both of theirs had different valves which didn't exhibit the same behaviour. One of them did leak though, and was able to be stopped. There is also not a neat way of securing the water bladder inside the bag, just 2 bits of short string, which you have to decide the best way to use. I guess you get what you pay for, as this is very cheap compared to other brands.

Je l’ai acheté pour la course à pied et il fait très bien l’affaire, en plus du sac d’hydratation il y a assez d’espace pour ranger quelque effet personnel. Il convient aussi pour tout type d’activité. Il ne coule pas. Pour le prix on ne peut pas demander mieux.

Absolutely love this bag. It's light weight, it's easy to pull the water reservoir out, and it has enough space to store some small items! Purchased it for music festivals and it works like a charm. I've ended up ordering additional ones for my friends since.

I wanna back my money this order is broken the water wash my back

Perfect for the kids to hike / bike and pack their own water. Enough room to put a sweater and trinkets in as well
