SunShack Hydration Backpack with 2L Water Bladder - Lightweight and Compact Pack for All Terrain Running, Cycling, Hiking and Camping, Black

This is a high-quality Hydration pack made from a strong material.The fabric is heavy duty and doesn't look cheap. The packet is large enough to carry things like snakes and even lunch. It is very comfortable to use it for a long hiking. By far this is the most comfortable Hydration pack that I ever used. It holds lots of water. You can fill half with water and it will keep it cold so you will be able to drink cold water during the hiking. This pack fits me perfectly and it is extremely light.

I used this for Spring Awakening Music Festival (90° weather in June in Chicago). Was easy to fill, however I couldn't get the pouch back onto the hooks due to the small area used for it, and really no easy way to do so - but that wasn't a big deal. Water warmed up in the hose quit a bit, but water in the pouch stayed cooled for a handful of hours - which was good after making my way towards the front of the stages. The mouth piece at first was intermittent and took some finagling to get it to work, but after a handful of tries it worked flawlessly. I also liked how small the bag was, amost felt like I wasn't wearing it all day.

The backpack is really comfortable and nice.. good for a long distance runners. You can use the backpack with or without the bottle. I ready tried an other backpack but this one I like better.

I once gave it for 3 stars, but after using it for trail running, only one star is enough now. the mouthpiece was very very easily torn. I took its tube off to clean it up, O-ring slipped off, gone. the result of its, water is leaking. it is quite difficult to refill water and hang a water blader. the backpack is such as a very good quality but the water blader is very poor.

Unfortunately only lasted about 2 runs and leaked. Not sure if it was defective or user error? Continued using backpack however which held up nicely.

Hydration pack is what I expected. I had plenty of water for run. I used for running so the straps did rub my shirt. I think it would be better for biking and hiking. Only down fall is hard to dry. Well made product and very useful.

Used this CamelBak for a family camping trip, and it served us very well. Throughout the trip we probably refilled it 4-5 times a day (my wife and I both drank mainly water the whole time). The seal was also tight and durable which is a huge plus, as I've had other more expensive CamelBaks leak on me, which is never a fun experience. Finally the storage room besides the bladder was quite nice, we were able to comfortably store most of our small items without any hassle.

Use it on my daily runs and it is very lightweight will be perfect for a marathon
