Hi, Wondering if this cup still is leak-proof...as often mine don't leak until a few weeks have passed...also does it travel well, packed in a bag or cooler. thanks :)

It travels VERY well, but does sweat with very cold liquid. We use it daily and I have noticed after continuous use, if I shake the cup really hard it will leak a few drops. I does not leak during regular use or if left side ways on the floor.

Besides the nalgene cups, these are our other go to cups. The only time we've ever had a leak is when I had the top screwed on wrong. I did purchase the lids for traveling. I do dishwash them on the top rack with no problems. Hope this helps!

Yes, it's still leakproof as far as I can see. But we don't travel with it coz it's too small for a 3yr old :). We use it at home extensively and for water only. There are plenty of grooves in the cover for milk to curdle so I won't use it for milk.But I would think it will travel well, cos my toddler sometimes hold it upside down and shakes it and nothing comes out. I would put it into a separate clean bag on it's own tho, as the child's mouth will be drinking directly from the lid.

This cup can have a few drops come out if shaken really really hard. It doesn't get worse over time. It travels in my diaper bag all the time with no issues. Hope that helps!

So far it has been a wonderful cup I even bought a second one sometimes if you fool it to full it drips a Lil but I've had it for about a month n they the only cup I use now

I think That is only for travel purposes if you don't want the cup to leak. I just discarded that because even in the diaper bag while we are traveling only a small amount of water has ever escaped.

I've checked it in luggage a few times without issue. Not carry-on though. I put it in a ziplock back in case pressure were to cause any leaking, but I do that with all liquids in checked luggage.

No, my cup is not corroded on the inside. I have had this cup for several years and it is my favorite cup when I am not traveling. It is not spill proof, that is my only complaint.

We have had two of these for awhile now (1-2 years). One really large one and one medium size one and neither has leaked yet from the bag. We will probably need to replace one of the mouth parts soon as I have noticed one of them leaks now, but even that is a slow drip.

It does not leak from the seals, though there is nothing stopping the liquid from coming out of the sip hole if it were tipped over. It keeps the liquid very hot for a long time, it is easy to sip from though. I sip test it without scalding my mouth. I've really enjoyed just about everything about the mug so far.

The directions inside say to wash by hand. The lid and top appear to be thermoplastics, which could warp in high heat, ruining the seal.I have always washed by hand. The seals are so good that my cup can roll around on its side on the truck floor board, full of hot coffee, for 30 minutes, and never leak a drop.This is an excellent travel cup, the best I can find. I tried several others, but this is what I buy and recommend to my friends. Hot coffee stays hot for hours.

We haven't had any problems with leaking if the lid is on right. And if you are sure that the rubber little sip lid is closed all the way down. But, we don't usually put it in a bag because some of the reviews said theirs leaked all over. It has been upside down quite a few times though and never leaked. but for some reason this particular bottle, and only this particular pink one (we have a few), has an issue with the lid going on straight. I have to check it every time we use it to make sure it's on right and it often times takes 2 times of screwing it on before its on right. But that's not a big ideal. Overall a good bottle.

No problems at all with leakage. I have it thrown in my bag in transit or if I'm not using for a while, so it's not always flat and never leaked. I've bought three (3) sets since the first set worked well and continue to work well. And I'll be buying more in future.

It keeps warm for atleast 4 hours but it is not 100% leak proof, liquids might spill if there is a lot of movement during transportation.Try to keep it straight.

I've only used the cup for cold beverages. I would contact the manufacturer concerning its ability to withstand a hot beverage. I love the metal contigo coffee/tea (travel) containers.

It has leaked for my wife but not myself (we own two). It would seem that the quality of the seal varies. Due to this, I can't safely recommend this for bag carry.

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!

It's leakproof and you can flip it upside down without leaks. This cup is amazing and keeps your drink warm for over 2 hours.

It doesn't leak and is sippable while walking. Mine doesn't keep my coffee very hot though. One hour in the gym in the morning and my coffee's cold, even when I wrap it up in a blankie.

It is not leak "proof" due to seams but it is lined with a plastic-like fabric that would definitely deter any leaks! I traveled with this carrier with United airlines and they said it was perfect. In fact, many other people in all the airports I've seen have this exact carrier. If you have any more questions please let me know!

As others have mentioned no, it isn't a good cup for travel, we only use it at home in a high chair because it can easily make a mess. I don't know that I would take the advice of another person that answered that hasn't used the cup though. We use it frequently, and only started with one top and it worked great.
