If it’s not closed tightly enough it will leak. That’s true of most mugs, but for some reason this one did this quite a bit when I first started using it. I had to get used to it. You have to close it very very very tightly! It no longer leaks but it’s hard to unscrew at the end of the day. That’s the only downside. Other than that, it’s great! It keeps my water cold all day, and the filter it comes with is perfect. It stays put and comes out easily. It’s great for infusing my water with herbs. I also love the additional rubber bottom cover option for the mug. It’s very easy to wash and clean the rubber pieces that come out (easily). It fits perfectly in my backpack as well. Get one!
