How leak-proof is it? I expect to slide it in a backpack so it would have to keep liquids safely inside if it falls over or even gets upside down.

Leak proof about100% for mine, currently about seven month. I had another one started leaking after 1.5 year.

Very leak-proof. I carry it in the side pocket of my backpack all the time, and it's even fallen out onto the ground without spilling, as long as you screw the cap on tightly.

It is perfectly leakproof. I threw mine in my bag for months with not a drop ever spilling.

Absolutely leak-proof. This was one of my favorite purchases of 2014. I highly recommend it.

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.

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.

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.

I would not use this for leaking liquids...it may hold up but does not appear to be made for that unless you put a plastic bin inside of the compartment to put the liquids in....

Yes, you should be able to lock it for travel so it doesnt leak. The bottle has a pump at the top, you twist it to unlock it and then you can press the pump down. You twist it back to its original position and it will lock so the pump doesnt go down.

This is absolute leak proof. At least so far I never had 1 drop coming out of it!! Im sure you can take it in a backpack.

There's a plastic domed lid that very tightly seals the bowl. Just don't put super hot liquids in it, and it's good for traveling. Yes, it goes on upside down, and unless you're concerned with the appearance of your food - soup, salad, rice - whatever else you'd want to put in it, it's a small price to pay for the cuteness. I haven't had any problems with leaks even when the bento is assembled for carrying. Best recommendation is just not to overfill it. Hope this helps! It's been one of my favorite Amazon purchases.

I have only used a cold pack with this cooler, so I'm not sure how ice would fare. I think if the ice were placed in a resealable baggie, then placed in the backpack, it would not leak.

It doesn't fall over easily, wobbles but tends to stay upright. And if lid tight it doesn't leak at all when tipped or upside down.

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

100% spillproof! i've turned it upside down and shaked it to show my wife, she carries important files with her purse/computer bag. if you want i can post a video tonight pouring coffee and shaking it upside down. I know how important it is to invest in something that works and not get burned by it, no pun intended.

It is completely leak proof. I regularly throw it in my backpack and no problems. I primarily use it for coffee, but also tea too. The drinking surface is plastic and sometimes it is stained black from the coffee until I wash it. I'm willing to bet the flavor would leak if I were to just rinse and drink tea...

The Bento box wasn't designed to keep liquids, it has never leak on me but that's only if you keep it standing up. The seal comes off very easily. sooo I would say no. The seal is not very good.

There is a closed durable plastic "U" design, that moves up and down. I use this on my an clip to my backpack. If you need pics let me know. If you have a "D" ring (rock climber stuff) you can attach it. But by far this is the best water bottle I have owned, no leaking whatsoever! Need pics let me know.

Yes, it is leak proof. Keeps liquids hot or cold for hours. Bought them as gifts for friends. That's been over two years ago and they still use them almost daily.They are awesome and sharp looking.

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.
