Follow up to is it leak proof. I going to be putting it sideways in a carry bag. Is the cap secure enough to stop from leaking all over in my bag?

If the cap clicks tight you should be fine. I have tipped my new bottle over and not had a problem. However, if there is something else in your bag that might "uncatch" the lid, or it gets loose through the years, it will obviously spill. It's not going to just open by the shear force of the water itself - something would really have to snag it. All that being said, I did have my old one come open and everything in my bag got wet - but it might have been my fault in not snapping the lid shut tightly. Hope that is helpful. I really like this bottle and think it might be worth the try. If the cap clicks tight you should be fine. I have tipped my new bottle over and not had a problem.

If cap screwed on tightly & flip top secured it will hold. I would make sure everything is secure by turning it sideways for a second before inserting it into carrying bag. I've dropped them before without spillage.

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.

I would be careful it's hit or miss and if something if something in the bag rubs the cover the wrong way it will open

No it is not. You will have a wet bag guaranteed. A better option is the Nalgene OTF bottle. It costs a bit more but won't leak. Just remember to take out the little rubber stopper and wash it every once in a while. It tends to mold.

This is a great water bottle. Prolly not good for just throwing it in a bag.The lid could pop open.

No problems here. The lid, if shut fully, does not leak on the one I bought.

Unfortunately, on mine, with the lid on, mine does leak when it is tilted on its side. They need more of a silicon plug at the end of the cap

No its just a cap but when tightly sealed, I've never had problems of leaking when it falls over.

It fits in the side mesh of a fanny pack. It won't leak, even upside down unless the bottle is squeezed. If you put it in a backpack just make sure it's upright and secure.

I haven't had a leaking problem, but decided to experiment to answer your question. I filled it and put it on its side overnight - no leaking. However, when I vigorously shook it upside down, there was some dribbling. I've been very happy with this bottle so far.

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!

They lock really well and I haven't had any problems with leaking. I often keep them in my bag while walking to work - they turn sideways/upside down frequently and I don't worry at all about them leaking

I've brought this backpacking on an overnight trip and I've brought this on many day hikes. I've never had it leak and I've stored it in a bag on its side with confidence.You should still be super careful about putting this next to a laptop. User error is the most common reason for issues with this bottle. But, the bottle can still be punctured or popped with a bunch of pressure if you fall or whatever.

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.

It is not designed to function like that. It will leak or the cap will fall off if held upside down.

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.

As long as the flap is closed you can turn it upside down and it will not leak. SEND IT BACK!Good luck,Mike

These fit most bottles but once you open/unseal it to drink, it won't be able to hold the liquid inside when you place the cap back on for later. Hence, expect some leaking if you're gonna put the bottle in your bag on the go..

Assuming you have the cap on and tightened appropriately, it will hold the water just fine. However if it's upside down and in a bag, there's a decent chance that something will push on the cap's clip/lever with just enough force to open it. Remember, they're meant to open with the force of your thumb, so that's all it needs for something to dump the liquid inside.

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

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 have three and they have not ever leaked in our back packs or beach bags. But if you flight check in inside your luggage, pressure will force it to leak.
