Replacement Lid for Hydro Flask Standard Mouth 12, 18, 21, 24 oz Water Bottles, Accessories for Hydro Flask and Most Sports Water Bottles, Lid for Hydrofklask, Leakproof, BPA-Free

Works well! Durable!

We love that we were able to buy additional covers for our water bottles. Number one, most of the bottles we purchased did not have the sports bottle (pop up) cap and this is the style we use. Also, if you have teenagers that use these and drop them just right the top can break. It was not the quality of the product that caused it to break, it was how it hit the hard surface and caught the lip of the mouth piece. They fit all brands that have the 1.8" dia opening. BE SURE TO CHECK THE OPENING OF THE BOTTLE DIAMETER before purchasing. We have several different brands (purchased because of color/pattern) and this fits all of the ones with the 1.8" dia opening properly and without leaking.

I bought this for my Hydroflask. Amazon was out of the Hydroflask brand sports lids, so I decided to try this one. When I was drinking from it, and the water does not come out from the spout very easily since the top that pops up and down does not stay up and open. Then, the last straw was that when I tried to get more flow out of it, it spilled out all over me. I'll wait for the Hydroflask lids next time I need one instead of being impatient.

This is a good product. Just make sure that you close the top lid on tight. It leaks. Make sure the mouth piece is closed, too. It also leaks.

UPDATED REVIEW: (changed to 3 stars from 4 stars) I just had to order my second cap. I contemplated going with another brand, but since the name brand one, being a softer plastic, wore out and leaked, I really didn't want to pay several dollars more for that one. I am a bit frustrated that, after a few months, both brands I have had have needed replacing. This is my third sports cap in 2 years! The softer name brand deteriorated, and this harder plastic one lost the little piece in the middle that prevents the cap from leaking. This one is taking a bit of getting used to as the cap does not want to stay up when I am sipping out of it, and I have to rotate the spout a bit just the right way to get it to not close while I am drinking. But it seems like there is no perfectly great sports cap out there, so I am stuck with it, I guess. ORIGINAL REVIEW: (I had given 4 stars at this point) I bought this when my name brand sports cap was deteriorating. While I like the hard plastic part better than the rubber as far as seeming like it may not wear out as fast, it's not quite as easy to sip out of and seems harder to not make a loud sound as I pull my mouth off, which is a bit tricky if I'm in a place like church or a movie theater or something. It sticks up a bit higher than the mouth piece on the name brand one, and I believe the part you hold onto has a slightly smaller hole for your finger, but that's not a big deal. I've had some condensation on the top, but no leaking that I've noticed if it is closed up.

Works great with my Hydro Flask! I didn't like that I had to use two hands to hold the bottle and unscrew the lid and then find a place to set the lid down while driving. With the Topoko lid, I am able to use one hand to lift the spout and drink. The water still stays cold as long as you close the spout after drinking. Excellent product!

The mouthpiece is a tooth-chipper if you are not careful. It is not the same as a Hydroflask mouthpiece which is soft. It is smaller and much harder plastic. Because it is smaller - when you drink, your nose is slammed up against the carry loop. It fits on the bottle just fine, but it is not a good replacement in my opinion.

Fits just right. Doesn’t leak at all. No reason at all to go for the higher priced ones!
