Does it leak in a bag or upside down?

Mine doesn't leak in my bag while walking. In a bag while chasing my preschooler it almost always leaks, so it depends on the activity.

No it doesn't leak unless you accidentally screw the lid on wrong (which I've done a few times). I've just learned to tip it over in the sink to see if I got it right and water isn't gushing out. The other time it leaked slightly is when I was rummaging in my gym bag and the stopper was tugged off. I'm more cautious about that now as well, and it hasn't happened again.

We haven't had any problems with leaking if the lid is on right. And if you are sure that the rubber little sip lid is closed all the way down. But, we don't usually put it in a bag because some of the reviews said theirs leaked all over. It has been upside down quite a few times though and never leaked. but for some reason this particular bottle, and only this particular pink one (we have a few), has an issue with the lid going on straight. I have to check it every time we use it to make sure it's on right and it often times takes 2 times of screwing it on before its on right. But that's not a big ideal. Overall a good bottle.

With this open drinking top on it will - I have bought a few of the solid screw on tops for when am doing errands for the day, shopping, hiking or traveling so I can throw it in my bag and not worry about it. I use this open top for around the house, gym or in the car. the 16oz fits great in cup holders, the 22oz does not.

It has a twist lid. I have had this now for several months and it has never leaked.

I've never had a problem with it leaking. I throw it in a bag for the range and never think about it until I need a drink.

If the lid isn't on just right, the seal leaks very easily when the cup is tipped. It doesn't leak much upside down though.

I have never had any problems with this. I'm always on the go and toss mine around quote a bit in drawers, bags, every which way, you name it, and have never had any leakage issues.

Yes it stays on well. I've turned it upside down and it doesn't leak. Just make sure it's on properly.

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.

No it doesn't leak. I have had this water bottle on its side in the same bag as my laptop - no issues.

The bag goes comfortably around the container. I turn the container upside down inside the bag and there is no mess on the floor. I hope this helps?

No! Unfortunately it does not! But I have not had any problems with it leaking either. I just wedge it between my purse and the passenger side seat to keep it upright, or carry it in a bag.

Yes it does. I tested it out by holding it upside down and nothing leaked out.

i have my 70 pound bag hanging from a beam i installed in my house. i only have the bag up when I'm using it. i bought this water bag so i would not have to drill into the floor. i filled it with water and it does not leak. it has a very thick rubber inside and i doesn't leak.

Well, never had to test it out, but I would say probably not totally leak-proof. The inside lining is a very soft material, as is the outside of the bag.

I just held it upside down and it did leak. But the lid has bite marks in it from my kids... I bet it didn't do that until the bite marks.

There is a little drinking slit and that is never closed - so it would leak if turned on it's side or upside down.

There is a strap that goes from the bottom of the bag up and through the handle on the lid and Velcros in place. It is a sturdy bag and I have used it without it leaking.

So far, I have had no issues with it leaking. Like you, the bottle is sideways and getting moved around a lot in my backpack when I take it to work.
