Does the cap stay closed tightly, so that water does not escape?

Yes it stays very tight and does not leak!! I love mine. I have one at work and one at home. Use them everyday!

The red cap stays on, and water does not leak from there, but the white cap on the very top did not stay closed for me, so water leaked everywhere. I Hope this helps.

The first one that I bought about 2 years ago stills stays pretty tight on. It has got a little lose over time than what it once was but still does a good job. As long as it doesn't take a big hit I'm sure it will stay closed thru most things. The only time mine has come open from knocking it over or dropping it, is when I fell once and hit hard and the top came open. Hope that helps.

no, hair still gets wet but stays out of your face. This does not pull or pinch like other caps I have tried.

The lid seems to keep water out where I keep mine, it might be slightly sheltered under trees, but I havehad no problem.

No. It has a smooth edge and the water does not stay inside. It works well for us.

No its just a cap but when tightly sealed, I've never had problems of leaking when it falls over.

Not really. It still screws on tight and I have no problems with leaks or anything but when tight the hole in the lid is too close to the handle to make it easy to hold & drink out of. It doesn't bother me though because I use a big long straw to sip out of. Keeps my stuff cold all day & I love it.

The lid stays very well, we've never had it fly off. It keeps rain water out too.

I've never had a problem with any leaking through the cap, and I always set it on its side. I do make sure that the cover is on securely, of course.

It has a twist cap that closes securely. If you travel with children, this is a must! My daughter keeps one in her car and I have one in my"grandma" car. We did have a plane and we kept one in there too! Good for anywhere you might be stranded away from a bathroom!

The cap fits very well. However, the cap is solid crystal and does not have a rubber stopper. So, I can't say that it is air tight.

Yes it does have a cap. It's not exactly the tightest fit, it might get jostled loose actually...

Yep. But when its closed the cup is very water tight. You could shake it and nothing would come out.

I honestly don't know. I leave the cap loose on mine and that has prevented any pressure build up.

in my opinion it does have a tight lid but I wouldn't trust it enough to say watertight.

The cap is molded so that the area by the ear has more room - there's a bit of a 'bubble' built in for the entire ear area. then it comes down and the edge is similar to the rest of the cap - tight enough to (sort of) keep water out. After wearing several times I found that water did leak in. Same as any other cap I've used.

Yes it stays pretty tight, but not leak proof, even if the pour holes are covered

Yes & No. Yes the elastic is strong enough to keep the water out. It fits snugly. I have been on my "first" cap for the past 3 months and it's still has retained its stretch. I have been very pleased to find these. They are durable and large.
