I just bought this. Is it an air tight seal? Does not appear to be. I'm storing iced coffee in this pitcher and want to avoid further oxidation.

No, it is not. And glass is very thin, broke when placed a little too hard on granite counter.

I hand washed mine as I didn't want to damage the seal on it with the heat in the dishwasher. The seal on mine is airtight and I have not had any problems with it not fitting well either. It's sturdy and I am very happy with mine. I have sugar in mine and it does not dry out or anything.

I tried this afternoon to find out just how "waterproof" the carry case is (the answer is, not very). I added some water to the container, put the lid on, and shook it. While it did not pour out, there was no doubt that this lid is NOT a tight seal. I suppose that a large o-ring or perhaps some RTV could be used to seal it up, or a very large stopper would do the trick, but barring that, I would not carry wet tea in this unless you like tea leaking everywhere.

I've never had this problem. The spout is a small opening and the cup seal is very tight. In fact, I have the mug beside me right now. No issues here.

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.

It is not designed to be airtight. It has a series of holes drilled in the back for air circulation.

Holy smokes,I did at all pay attention to any of that. I just checked. The lid just goes on there. It doesn't screw on or anything, but sort of just sits on there snuggley. So not airtight. I've had it filled up, and have not noticed any deterioration in the taste of the coffee over time. I also cover the whole thing with a dark cloth.

Amazon (through Backcountry) has finally started selling the lid. It's not airtight (the tumbler isn't threaded for a cap), but will keep things the right temp longer and maybe reduce spills.http://www.amazon.com/Klean-Kanteen-Pint-Lid/dp/B00IPOT5B8/ref=pd_sbs_sg_5?ie=UTF8&refRID;=140VDB5S7KMC6A577RPM

It does have a seal , however I don't think it is completely airtight. We do use ours for coffee but we use the coffee at a quick rate so it is not a factor for us.

Since I don't live in a dry climate like Arizona I can't really answer your question. I can tell you it is not air-tight. We use it primarily to keep the counter top from looking uncluttered, plus the stainless steel finish matches our decor. We are able to keep our bread for weeks but I'm sure that's due in large part to sealing the bread up tight in it's original packaging. If you are looking for something air-tight, you should look at something like Tupperware or similar. Hope this helps...

No it is not airtight. I would not suggest it for something that needs to be stored in a airtight container

I would believe it is sealed. They are guaranteed tumblers. The company should be able to answer your question better. Good Luck!

I would say yes, it's air tight. There is a rubber seal around the top and it snaps closed. (There is no doubt it is closed tight with the snap) I love mine and even though the contents is several months old, the product is staying fresh

I use it everyday and it seems to work really well. The coffee is fresh and it is an airtight seal. I like it.

i own this, with a properly placed seal it should be airtight. the seals remove for cleaning. if you do not install them correctly then it will not be air tight. they are pretty easy to install. i am happy for the price i paid. tupperware made nice canisters but they will cost you twice as much and they are not clear.

I'm not really sure what you mean by airtight. It doesn't seal like a canning process does, but it keeps the contents of the jar fresh and I often shake mine without leakage as I use it to store smoothies after I make a large carafe and can't drink it all. Hope that helps.

No, it is not air tight. They go stale slower, but if the cup has snack in it that I think will take more than three days to finish, I just put it in a ziploc that I wrote "snacky cup" on (just so I didn't keep reusing ziplocs, being that they don't touch the food).
