I am worried about leaking at the mouthpiece or cap when the bladder is pushed on by gear in my pack causing pressure. Are they reliable?

It has an in line shutoff that can prevent this. It's built tough just for this heavy duty use. I've slammed my 60# ruck against mine without breakage or leakage.

I own 4, used them for hiking and they've never leaked (if you don't forget to close them of course!)

Very reliable. No leakage at all. By sipping the water or drunk goes a long way and is economic. I have used this for backpack hiking and cycling long distances. Great product!

The Osprey 14 is a great hydration and mountain biking backpack. I only had one leak issue when I did not take care to thread the lid properly. If done correctly there are no leak issues. I've hit overhead branches and crashed a couple of times without a single leak.

I have only had them for a short while, but so far so good. A friend of mine has had them for much longer, and I have never heard her mention problems with leaks. She seems very happy with them. The seal seems pretty tight.

almost no leakage. I've used them for years on-air with pretty heavy processing and no problems. Go for it.

water leaks between the housing and the filters but its not a big deal. If your diving just twist the cap slightly so water fills all the way, then twist back on tightly.

I haven't had any problems with it piercing caps, sometimes need to add a little pressure to get some bottles to pierce.

Yes that's what I have. Works great. I would get ospreys reservoir. They have the best bite valve

Yes, my first one leaked so I bought another and the second one leaks too. I may return it, or just use them in the car where they will remain right-side up all the time. Also, even when upright if the mouthpiece is open then warming air in the bottle will push a LOT of water up and out of the straw and all over your cupholder area. So if you use it in the car make sure to close it. I'd never carry one of these in a backpack. Water does really taste better though, so I'll accept the limited usefulness.

Yes. There is a sleeve inside the large compartment that keeps your reservoir secure and a small opening located at the top of the pack that allows your mouth piece and tube to be kept close and convenient while carrying your pack. Very well designed.

There is a pressure release on the ottom. No doesn't leak enough to merit giving it a bad review

I've had it for 2 years, use it frequently, and have had no leakage problems. I do have to use a nose clip. This is an excellent product which I highly recommend.

It snaps tight and has never opened on me. Now I've noticed that some click closed easier than others, so you'd need to be certain it clicked shut, but they've all been very reliable as far as leaking. The only issue I've ever had is if I don't screw the cap on tight enough, it dribbles but that's on me.

I have not had that problem, nor has the guy who recommended it to me. I don't put it to aggressive use though. I love it, and its very comfortable to carry on your back while carrying other gear. Highly recommended for cost.

any will work; I used a 3L camelback.beware; it's A) a tight fit for larger bladders and B) will make the pack sit really awkwardly and uncomfortably on your back when it's full all the way.Kinda doesn't make sense that it's right against your back - the front the pack would be a better spot as it would ride better.I highly recommend MSI's dromedary if you need to pack in your own water. those things are unkillable.

Not a problem, make sure the cap snug, do not try to tightened it too much. I sleep with mines all the time with no issues.

I have not had any trouble with the valve on the back booster. I have taken on multiple overseas trips and it has held up very well. You should wait until you get to flying altitude before you blow it up. If you inflate it early it will puff up even more when the plane takes off. I have had two spinal fusion surgeries and this pillow is totally awesome. I would recommend it to anyone even if you do not have back trouble. I sometimes sit with the wider part up and other times put the wider part down depending on the contour of the seat.

I have 3 of them and took them backpacking with pretty full packs and none of them leaked. But, with that being said, I'm not sure I'd chance it with my laptop unless there was a divider of some sort.
