KOOKOOG Sports Hydration Backpack Water Reservoir Bladder, 2 Liters (70 Ounce)

I bought this hydration pack for it's looks, pockets to store a few items and size. Love the color. It is also perfect for my daughter. I have had a hard time finding one that the straps could since up and not be too big for her. She is 70 lbs and is 4'9". It fits me perfectly as well. We had trouble at first with the water bladder leaking. The company contacted me by email after leaving a less than 5 star review due to being disappointed with the hydration bladder leaking. They immediately sent me another hydration bladder. We have used it a few times over the past week and so far it is great. No complaints with the backpack it is awesome. The hydration bladder is great as well. Would recommend the company and there product.

This pack is a great size! It is great value for the price. I ordered two packs and one is great; the other has one slight issue. One zipper on the main compartment area is not working, so I am limited to using one zipper to access that main area. The pack is still functional, but it would be much more convenient if both zippers worked. Otherwise, I am pleased with my purchase.

i don't understand why some manufacturers don't include instructions with the package. do i need to rinse/wash the pouch before first use? the backpack fits comfortably; i have a 48 chest so the straps make their way around just enough. gotta seal the hose really tight otherwise you'll have leackage in the bag and not realize it until later on. plenty of space for phone, wallet, keys, etc. draw on the hose is decent.before i ever took it out on the run (and I haven't yet), i put 1.75L of water in the pouch and walked around the house with the backpack on for a few minutes....realized that i hadn't tightened the hose enough.....the back of my shirt ** and whatever I would have put in the bag ** would have been soaked. I have never used these before....and i can't figure out what the hell that stupid little hole is in the top (blue) part of the bag. of course, instructions would be awesome!!!looks like a decent product but i would have given 4 (maybe 5) if instructions were included on best ways to use the product.

Got this hydation pack at the end of January, just a couple of months ago and have used it only a few times and the zipper on the main pouch is already broken. I gave it 2 stars because the hydration pouch itself works great, no leaks. Really disappointed that the pack is not functioning properly. I would of returned it to Amazon but it's past the return time of 2 months.

I had really high hopes for this hydration pack based on the good reviews, plus the cost was unbeatable compared to other competitors. I was very please with the space to carry extra items, including lightweight jacket and the nozzle to drink from, which has a cover to keep it clean. However, I have only used it for the fourth time now and the seal started leaking, under where you twist the lock into place. Super bummed, as I really liked this pack overall. I'm only able to fill it to a 1 L line now, which I don't find to be useful for a longer hike.

Quality for the price. I bought this for my average sized 10 year old boy. It was way to long to fit him properly. Definitely not for a youth unless you berthed a giant. Also the color is very feminine. I would not recommend this for a male that is sensitive about the colors he wears. I returned it for a prompt refund.

Got this in time for my hike. I tend to get more parched than the average person and don't want to be lugging on a water bottle so having this conveniently part of my backpack was AWESOME! It is very lightweight. Bag did not look bulky even after filling the pack full of water! Highly recommend this! I still had room for an extra shirt, a face towel and some light snacks.

I ordered this hydration pack in preparation for a three day music festival. The product came in a timely manner, however when my boyfriend went to use it, the bladder started to leak water. We couldn't see the hole but it ended up being useless.---After leaving the above review, the seller contacted me and said that they are willing to send a new bladder because of the faulty bladder.Besides the faulty bladder, overall a good hydration pack. I would recommend. There is a clasp to hold the hose down and there is a mouth guard and nozzle cover. Overall good quality.
