Good modification for RTIC bottle
It fits well on an RTIC 20oz Journey bottle. The spout angle is perfect, very easy to pour water into one's mouth. Just the right amount of flow for me. Easy to unlock and open one handed. Seems to be good quality so far. Doesn't leak.

Great fit, no leaks
They fit my older hydroflask bottles perfectly. Pop open easily when you push the button, and no leaks. Love the flexible carry handle too.

Perfect fit
Had to replace my old lid (pictured on the right). This fit perfect, and works as stated. The plastic is smooth and the color is black. I put water in the bottle and turned it upside down and there were no leaks. Very comparable to my other bottle neck (length of a size double a battery) and easy to wash without needing a bottle brush.

Works well with one flaw
This lid is to replace one of my lids for Hydro Flash water bottle. I like the flip top, and the locking mechanism. It works well. It didn't leak for me at all, which is good. What I don't like about it is when you sip, there is no air release so it causes a suction. You have to sip with air flowing through the opening. Not a big deal, but would have been nice if there was a small opening to let air out so sipping would not be an issue without the suction being created. Other than that I like it. Hope this helps.

Best lid for my Hydroflask
By far the best lid I have used for my Hydroflask. This fits perfectly and I really appreciate that you can easily clean all the nooks in it. The locking mechanism is super helpful for ensuring the lid doesn't accidentally open. I bought a second one for my husband.

Great product.
Fits narrow-mouth Hydroflask perfectly. Great product! Much better design than Hydroflask’s lid.

Not Great
Adds a lot of height to the bottle. It fits perfectly but doesnt have an air return/breathing hole, with a really small drinking hole. Its not really easy to drink from.

No leak Hydrofask small mouth lid
This is a great, no leak lid that has a lock. We ended up buying 2 more for our other hydrofasks.

Tapa abatible
La tapa quedó perfecta para mi termo hydro flask de 21 onzas. Cierra perfecto y no se derrama el líquido. Buena opción de compra.

Works as expected
Fits great, works as expected. Easier to drink than the stock twist cap. So far so good.

Perfect
Excellent fit, works well, a bit expensive for a cap in my opinion but rather than a new bottle, just a new cap, less waste.
