Is it "leakproof" even if it falls sideways in your bag?

If it's completely closed I haven't had any leaks. If water is in the closure it would probably leak but just a small amount.

Yes it is, if closed and sealed correctly it will not leak. I have mixed tea and shaken it and have had it laying down inside my travel bag and does not spill one bit.

As long as you have the top on tight and the straw top closed I'd consider it leakproof. That said, I have had mine leak if the straw portion wasn't shut 'just right'.

As long as it's closed well I never had a problem. I threw mine in my backpack and tossed it in the car seat, never had a puddle.

Yes it is leak proof as long as the rubber straw part is in place and the lid in the closed position. I've had no problems with mine. Hope this helps.

It is leak proof. Even by leaving it unlocked it won't leak. I still lock out every time I throw it inside my bagpack, just in case!

Yes but don' t lay the backpack upside down or side ways because water will leak through the zipper of the cooler bag and you don't want to get the pump wet.

I have only had mine for a few weeks. It does not leak. However, if over-filled, it will easily spill when walking outside with it. I find it can only be filled about 3/4 full.

Yes, very leak proof. I carry it in a bag all the time also throw on the seat of car. I own 2, neither have ever leaked when they are closed.

No leaking issues, travelled to Jamaica with it. p.s. you could always put it in a ziplock bag.

Yes as long as the gasket is in place and you completely screw it tight, it will not leak! I've turned my upside down many times or it has fallen and nothing leaked out.

It doesn't leak if that's what you mean. I have been very happy with it, it's very big so can fit lots of diapers

Only if the explodes, which doesn't seem likely. Mine came inside a plastic bag, so, it won't leak even if the bottle somehow breaks.

No. It leaks. I had LOTS of trouble getting the lid to screw on level. This resulted in a dribble from the top when I tipped it on it's side to check if it would leak. I was NOT happy. I wanted to carry this in my backpack for hiking. Can not do with a leaky thermos. It is SO pretty I really wanted to keep it. But for this price, a leaky thermos has to go back! Darn.

When the bottle is upright, a few small drops of water can escape from the air hole. Once the bottle is turned upside-down water won't leak from it

Yes, I have traveled with this and no it did not leak. I would still put it in a plastic bag.

Yes it will leak. I have carried tea in it to work and had this issue. I now keep it upright.

If I walk in the rain with the bag for a while, it is not a problem at all. But if you soak it in water, I am sure it will leak somewhere. I am very happy with the bag, good quality.

That is what I wanted to know...... It is very helpful to know that it leaks if it is stored horizontally. Thanks.

Not even a little! (Being the scientist that I am I had to test... Put just water in, laid it on it's side then upside down. No leakage.

I own two of them and have not had any water come through the zipper. If you had it upside down and there was water in it, then I guess eventually water would leak out.
