Lightweight Hydration Pack - 2 Liter (70 Ounce) Hydration Backpack Bladder - Biking Trail Running Walking Hiking - Fits Men Women Kids - Mochila Hidratación

This Hydration Pack is awesome, it's very comfortable for long runs, easy to fill up with liquid, easy to put on and strap up and easy enough to drink from. A minor issue is the that on the straw tip there are markers for biting in order for the liquid to come out if you don't bite them on the markers the liquid will not come out. It takes a little effort to get over that setback but overall it's a great buy and it will highly recommend it to potential buyers.

Really good, very light weight even with water. Only reason im giving it 4 stars is because the drinking tube is hard to use ( i could just be doing it wrong though)

I was depending on this on a field class to the Amazon. It leaked all over everything in my bag from the bottom the first time I used it and ruined my notes and soaked my change of dry clothes.

The straps rub against my skin and made it raw. The water doesn't really stay cold like it should and the tube is hard to suck through. Also the middle strap doesn't really sit under my boobs even all the way down

to small of a fill cap not triple stitched like better quality ones are, Price is better than some of te better quality ones but I doubt it will last a fraction as long

Great Value and quality for the affordable price tag. Lightweight but still very durable. Fill cap and bite valve are good quality and drink tube is even insulated. Final plus is that the hydration bladder itself doesn't have the usual plastic smell/taste that camelbacks and others tend to have. Would definitely buy again. 2/25/17 add'l info: I used this pack in my Spartan Race Sprint and it held up great even with all of the beating it took. Also, it was the perfect size to offer enough water but be compact enough to fit thru the tight obstacles like the barbed wire crawl.

I recently purchased this for a festival and I must say no complaints or problems at all. It kept me hydrated entire night and very lightweight. It was a little hard getting the water out which is the yay and nay in all hydration packs. All in all two thumbs up and cant wait to use it for nextfestival or hike.

very happy with it so far. I've used it on one 4 mile trail run -- a good test of its ability to hold firm to the body -- and it did fine; no bouncing. And the most important test of all - its ability to hold and dispense water. It did well at both -- not leaking and, once i figured out how to use the mouthpiece, great at providing easy sips AND full blocking of water when you're not sipping. No instructions made it difficult to figure out the mouthpiece, which is different than any other hydration pack I've used. The short story: pull on the mouthpiece til it pulls out, and then the water flows freely. Push it back in when you're done and the water stops completely.
