All I can tell you is that I have 2 of them and they don't leak through at all. They are amazing.

Water will not go through the plastic. However, water may get under the plastic since it does not have a base to it.

Without emptying it and filling with a thinner liguid ,I have no idea. I have 3 and have no leakage problem.

it has a mini container that is separate with a screw cap lid that fits inside the circle area. so leak proof....

If the rubber sealant is tightly in place inside the lid, then there is no leaking at all. I filled it with water to test and it did not leak.

I haven't tried that yet, but if you seal the lid on tightly (and there is a trick to doing that) I suspect it will not leak. I suspect the biggest problem will be when the plastic lid starts wearing out and becoming more brittle. Then it may start leaking.

Mine has been great it does not leak you might want to check and see if it came with a hole or if something happened to it after you got it

It doesn't leak it only overflows if I don't empty it enough (my first 3 days are RIDICULOUS so I wear a panty liner to bed on those days) But on the lighter days I sleep with it all night no problems!

It doesn't leak, but one does have less gel and a middle seam. When you order 2, they both should be the same, right? In this case, I received 2 different ones and they perform differently from each other.

It's a type of plastic, and this is a WONDERFUL product! If you install the spout piece carefully, it does not leak. Because the device is not glass, it's not heavy either. One of my best product buys this year.

ours does not leak and the flexablity and extra length are nice...perhaps you received a faulty one

there is a slide that slides over the hole to drink out of but it is not leak proof. One slight tilt and your beverage leaks all over. Yes, the inside is plastic. I was extremely dissapointed that a Thermos product was not leak proof. I dont recomend the product

Hasn't leaked yet.. as long as you don't rip the liner, I don't see why it would.

The clear plastic insert attached to the bottle is supposed to fit inside the bottle lid. I have two bottles and when lid is screwed on there is no leakage on either one. I wonder if there is a defect with the clear plastic insert or the lid. You might check to see if the clear plastic is inserted rightly into the bottle. I have tested mine a few times after reading this, and mine are both sealed tight when lid is screwed on. You might contact seller. I am very pleased with my product.

It's has a waterproof lining. Don't know what it's made if but it's like plastic but not hot
