Is this at all leakproof? I know it's not a thermos, but I'd love it if I could hike with this, but it would bounce around somewhat.

Mine never leaks. Just make sure that the screen is screwed on before you pour in hot water or it won't seal properly but all strainer cups are like that.

I didnt have any issues with leaking but I didn't take it hiking or anything of that nature.!

Yes! I have knocked it over and never a dropped spilled. Inside the lid there is a thin waxy like substance that when you put hot liquid in activates sealing it. If you tilt it while it is full I recommend waiting a moment to open it though as with the metal mesh strainer inside it takes a moment to drop back down into the cup.

I have had mine for over a year and it doesn't leak as long as the lid is snug. Make sure to wipe off the rim before screwing on the lid. Like you said, it is NOT a thermos and will NOT keep your drink hot or cold for more than ~15 minutes.

It is rather leakproof, but if you were hiking and had this in your backpack I am sure it would open up at some point and begin to spill. I would recommend just using a thermos and a tea infuser instead.

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.

I would trust Anthony's answer. But, remember, it doesn't leak at all, so none of the water spills out. I used to keep mine in my purse (I used it to train my dog when she misbehaved, but I don't need it any more). It also fit in my sweatpants pockets for our walks up Kennesaw Mountain. (It was bulky, but it fit.)

I use it on a school bus. I have two of them I carry on the bus. They bounce around a lot and I've never had a leak except when I overfilled it.

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

It's not designed to hold water and transport water at the same time. It's great for hikes, walks and I imagine it would do well at the beach. All it does is unfold and act as a container. When you try to pick it up it's flimsy. Therefore it works great just don't pick it up and carry it. I do recommend it.

I'm not familiar with the thermos mug but I really like my Stanley mug. We have two and have had no issues with leakage while driving or hiking.

I do not live in such a climate so I am unsure. I haven't had a problem with leakage though, I travel alot!!

I don't think it leaks. Not sure about how well it keeps things hot/cold. It's a novelty item. I bought it for my sister. It does look authentic tho.

Haven't knocked mine over "yet" so I filled it with water, put the straw in the lid and turned it on its side to test it. Water came out of the minimal area around the straw. A rubber gasket holds the lid on very tightly, but there is no gasket around the straw area. Water will leak at that point only. I love this tumbler and use it as much as possible.

Hi! No, it is not leak proof. When traveling with it I take extra precaution to not fill it too close to the top as well as snuggling it between other things so that it will have less chance of spillage. Otherwise, I try to plan meals for the thermal cooker with foods that aren't so liquid-y, like stews or pottage-type lentil stew...not really soups. You may still get a little spillage inside the cooker but that is why the manufacturer recommends placing a folded paper towel on the bottom. If you have sauces you might want to consider placing them in sealed containers then in the cooker to keep temp. Have not tried but just a suggestion. Hi! No, it is not leak proof.

Once this is fully saturated you can fold it. I have folded it and doesn't seem to make it leak. But make sure it is fully hydrated.

Yes-- it slides in and out very easily. It's easy to fill--just make sure you tighten the lid correctly or water will spill. I've walked close to 500 miles with it and love it.

yes! It is actually engineered to hold hot water and I read that many have put it in their sleeping bag! It does NOT leak!

I shouldn't leak at all if you have the lid snapped on firmly and the little vent hole cover snapped into place. It's a rubbery lid that seals pretty tightly and takes some effort to sort of "peel" it back off the cup when you are ready to eat. I've never had any spillage in my fancy tote bag I haul lunch in.

As long as you lock the top switch, it's completely leakproof. I fill this with coffee every morning and throw it in my purse - many times it's upside down. Never leaks even a drop.

It fits nicely in car cupholders. I have had only minimal problems with leaks and it is usually because the button to open the top accidentally gets pushed. If it does not get threaded on properly, it could leak but my experience has been that it has been the most leakproof thermos I have had and I have had many!
