I love my Swig tumbler that I've had for...two years maybe? Until recently, the regular lid that came with it was good enough. It didn't stop leaks if the bottle got tipped, but the bottle didn't get tipped often. Enter toddler. My baby loves my tumbler and as soon as he was big enough to reach it and grab it, it's been non-stop spills. So I ordered the leakproof lid and I am super happy with it. It really is leak proof so far as I have seen after using it for a bit.

Now can we please please get the leak-proof to go lid (with the top handle) for 40 oz Swigs!?!?

Love the new lids!!

Love the new lids!!

Does not leak and the colors match my tumbler perfectly!

Love that the lid is leakproof! I do agree with a previous review that the straw is in an odd location after it gets screwed on. I think I’m starting to get used to that. The only other thing is that I wish this came in other colors! Especially solid/1 color per lid. The current color options don’t match the cups I have very well.
