The lid is airtight.....the cup easily fits into my Car Cup holder and will Literally keep my water cold all day with a couple of ice cubes added.

Best tumbler I've ever purchased. Super seal on the lid. Drinks stay cold practically forever. Fast shipping and great price too, thanks !!!

Years ago I won a orca travel cup at an NRA event, and really loved it,since then I've purchased two more. Every bit as good as a comparable YETI for less money.

I have had the same cup for several years, bringing it to work every day, outside when working in the yard, and on the bedstand at night. It was basically working 24 /7 for about 8 years. I lost the whale tail closure on the lid a long time ago but it still performed perfectly. Over the years it was scratched but despite numerous drops, it never dented. In the last few weeks it finally started to fail to retain the cold so one of it's falls must have caused a leak in the vacuum. Without hesitation I decided to replace it with another Orca. It performs on the level of Yeti at a better price and has the very cool whale tail lid. I originally purchased at my employment, but since we don't carry Orca anymore, I ordered from Amazon and it was delivered less than 24 hours later. Excellent product with excellent service from Amazon. Thank you so much.

Let's get the bad out of the way:
The seal was kind of funky when I first got it. I got two. A blue cup with a white lid for me and a purple cup with a gold lid for my girlfriend. My alma maters colors are blue and gold. Her alma maters colors are purple and white so we switched lids. One of them was way too tight and she almost dumped the water all over the floor. One of them was a little loose and would leak under the mouth opening when you tipped the cup up to sip.

Onto the good:
That was over a year ago. After a few weeks of daily use, both of the seals normalized to a solid middle ground. It's tight enough not to leak. It's loose enough to pop off safely and easily. Same could be said for her cup.

If you keep the cup in an area out of the sun at room temperature and fill it with crushed ice and ice water, the water will be cold for about 16 hours. I know that because if I fill it up with ice water at the end of the work day around 5 and leave the cup at my desk. The water will still be cold at noon for lunch the next day. Cube ice will probably hold it even longer.

The cup is impressively sealed. My girlfriends nephews were playing with it and knocked it over while it was full of water. The lid was shut and only a small droplet of water popped out of the airhole from the initial impact. After it landed it rolled around on the carpet for a little while before we were able to get her nephew and nothing else spilled out.

It's very robust and that includes the lid and the paint. I was a little hesitant about getting a painted one because I was afraid it would get scratched up but this paint is very thick and very hard. It seems like it is cooked on. I've been using this thing daily for over a year. It's used in my office and car everyday. It's gone with me on countless fishing trips. It's rode in the cupholder of kayak on over a dozen paddle trips. The lid still looks relatively new. A small sliver of paint, about a 1/16th inch wide, around the bottom of the base has worn away exposing the silver metal. Along with a nick on the side caused by who knows what. The paint still has it's bright blue color.

It fits in every cupholder that I've ever tried to put it in. It also fits very securely in the water bottle holders on the sides of my two Jansport backpacks.

10/10 cup all around. I can't say enough good things about it.
