Does this leak at all? Can I toss it in my bag and not worry about it leaking?

It does sometimes in different altitudes and when you don't push the lip close

It did not leak for me but I empty it every few hours, the longest I have had it in was at night and I have not leaked yet

No problem with leakage...I mean you will be using a bag in there anyway...

Mine has never leaked from where the lid and jar form a seal. However, it would be easily spilled in a lunch bag because of the holes for drinking and air flow.

It doesn't leak at all. Very leak proof. I often place it in my purse where it is tossed and ends up upside down.

It does not leak at all, I can hold it upside down and shake it and nothing leaks. And that is after several months after using it, so the seal does not deteriorate. I don't know the answer to your second question as I always wash it after using it.

I haven't had a problem with leaking, but mine are still pretty new. I tossed a mason jar with smoothie into the diaper bag. It didn't leak. It was kind of risky, but I was desperate at the moment.

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.

It doesn't leak. It has worked really well for me. Some reviewers have said it is difficult to put on the bottle, but I have found it to be easy to do.

Doesn't appear to leak at all. We absolutely love ours and have had it for 7-8 months now I think. Very heavy duty and great quality.

Yes it is perfectly leak proof. You don't have to worry about its pose in your bag.

I have never had one leak. We use for lunches. I have taken them on carry on luggage.. I guess a thermos is another possibility.

I purchased two to take with us to Soth Africa and Botswana.I gave one to my wife and kept one. On the flight tp South Africa mine leaked a black oily substance onto my clothres in my checked bag. On the flight back it leaked a white viscus gel. Wiser by my firest experience I placed it in a plastic bag to protect my clothes.My wife had no problem with heres. That may be because se kept hers with his in her carry-on bag. Both worked and I'd have no reservations about buying one unless you plan to fly with it.

It is leak proof as long as you put the tab in the "lock" position, and have it assembled correctly. I throw mine in my backpack and the only time it leaked was when I forgot to lock it.

Ours hasn't leaked. I just make sure I don't overfill it. I did read somewhere that you're not supposed to leave water in it. I leave water in mine though.

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.
