Hydration Bladder 2L, ICETEK Upgrade Sports Water Bag Hydration Backpack BPA Free Safety Leakproof Water Reservoir with Self-Locking Valve for Cycling Hiking Camping Climbing

Been using this with a ruck sack, it’s easy to use, and disconnect from the pipe , to fill up or cleanHad no leaks, infact was thinking on getting another to use as an addition bladder when going out..As you just need to release the quick release valve and swap over bladders.. 5/5 from me

Bought this for a charity walk and it was a saviour. It's a great size, I filled with ice and it stayed cold for hours. It's also very easy to use, so helpful to have hands free access to water. I highly recommend.

I have more cons than pros for consideration, but this is actually a great bag.Pros:*A good amount of water can be filled that lasts me 4 hours of hard riding with some to spare.*Bag is robust.Cons:*Has a mild rubbery taste, to be expected.*Mouth cap is fiddly to recap whike riding, I just leave it off now.*The mouthpiece requires some getting used to, if you pull slightly too hard, you will get so much air when you drink. Not enough and you cant suck any water out.*The fixing point doesnt include a hook to hang in my camelback bag.Hints:*After a ride, release any remaining water from bag and tube. Rinse mouthpiece. Freeze the empty bag to stop mould growth. Months if use without any issues. Note that you should probably defrost the bag before bending it or it may crack, although I dont bother myself.

Only used it a few times so far and I really like it. Never had one before so definitely takes some getting used to it, I assumed the water would just come out but you kind of have to bite down on the end and suck same time to release the water. Holds 2ltrs which is more than enough for the walks we do. No leaks so far touch wood so would recommend on usage so far.

Cant really comment of durability have only used couple of times. But I am just thinking why I was carrying water bottles in all the climbs I have done so far , like seriously why ? Last week did Scafell Pike in the end it was over 1 l water left . If you run , climb or walk , stop carrying water bottles .

Worked very well for 2 months (fair use) then started to leak from the screw cap. Buy cheap buy twice .

Needed a new bladder for my bike back pack. This does the job and you can't complain at this price.

Bought as a last minute idea for our trip to Yosemite in USA. Absolute gem and worked like a treat! No leakage and a cover for the mouthpiece meant it didn't get dusty when on the floor.
