Is the cup-lid watertight?
1011480
It acts like a lid for a pot. It would hold in heat, but I wouldn't say it is watertight.

It is made of solid material so can be used as a cup. It merely sits on top and does not lock, so it would leak if tipped.

If what you are asking is- when the cup-lid sits on the lower pot, is the complete assembly watertight, then no, it is not water tight, it's not even tight, it just sits there. Having said that, I can store an standard gas pancake cylinder, upside down in the pot, and in the concave void of the cylinder I keep my Pocket-Rocket stove and lighter, then the cup-lid sits over that, and the whole thing fits inside the drawbag which came with the set. A new Jetboil does the same thing, but since I already had the stove and needed a lightweight pot to boil a couple of cups at once to replace a damaged pot, this was a good cheap alternative. Good luck. If what you are asking is- when the cup-lid sits on the lower pot, is the complete assembly watertight, then no, it is not water tight, it's not even tight, it just sits there.

no, there is a hole in the top. it is leak proof along the edge, allow the user to drink out of it like a travel mug. if you want something totally leak proof just use a normal mason jar lid.

No. It is a push-in style lid. The seal (on mine anyway) is quite good, though.

They are not airtight. Water will not get in. There is no seal, but the lid overlaps the side by 2 inches. The lid also fits very snug. I have used these for about 5 years now. They are very well made (good materials, heavy duty) hold up to lots of abuse and have a lot of space. I put gear I want to keep dry and safe in it and put it in the bed of my truck. I have traveled many thousand miles with these in my truck bed and never had any issues with water leakage no matter what the weather brings.

No. The lid closes fairly tightly. And it keeps items inside dry, as well. We've been very pleased with this deck box and even ordered another in a smaller size.

Yes, and the lid serves as a vacuum seal to keep the water overflowing out the hole in the bottom. I like how it's got a sturdy handle.

Yes, it is completely leakproof, which is awesome! There's a way to lock the lid out too so that you can't squeeze the button and let the liquid out. These mugs are the best!

No, I hand wash mine and haven't had any problems lid still seels well no leaks. Cups have done well for me planning on buying two more

It's fairly water proof. I've spilt a drink inside it before and it didn't leak.

It is not completely watertight. I've had no problems in rainy weather, but the car wash can get past the seal. The contents are safe in the rain. It's a great cover. Thumbs up.

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

The lid fits very well, although I don't believe it would be watertight. No rattling though, which i think is great

Not truly airtight. The glass top sits on the dispenser. It has a nice lip to hold it in place, but it is just gravity doing the work. But- the lid prevents contamination and would keep the drink from evaporating in the refrigerator. So I would use one in that way, probably a 1 gal or smaller.

I agree the lid appears loose. However, I've had nothing spill or even leak during traveling.

Yes. The lid does come off so I guess water could maybe get in (if submerged) but it will not leak (heavy duty plastic) if that is your concern. I ordered mine around 2 months ago and really love them.

Basically the answer is no because there are no seals to prevent water from getting in. It could be considered water resistant if rain is falling down on it with the lid closed, but not if water is sprayed sideways onto it where water can get under the lid.

It is not air tight; it has no seal or gasket. The cap goes on with 1/4 turn. I live in a low-humidity area, so I keep everyday coffee and tea in these. I use a Teavana canister for my more costly teas. You get what you pay for.
