EIPOSAU Auto Flip Lid for Hydro Flask Standard Mouth Bottle, Spout lid for HydroFlask Narrow Mouth Bottle, Replacement Lid with Button Lock

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.

Love iiiit!! So easy to press a button and the lid pop up for quick and easy sipping. It has a great seal but the downside of that is that it's a little hard to unscrew to refill. This isn't a problem; I love that it's leak proof. A great buy, for sure.

This is a great item. It’s an immediate upgrade.! push the button and the lid flips open. It doesn’t get any better than this.! great quality

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.

Really great. My only complaint is that I will inadvertently lock the lid, and initially when I installed it, I didn’t quite get how to use it. Seriously no big deal.

I have multiple Hydro Flask products and am currently using a 24 oz narrow mouth as my daily bottle. I had been using a Costco bought, Thermoflask 24 for a couple of years before using the HF when the TF could no longer get fully cleaned. The TF has a wide mouth cap, with a smaller, attached, sip opening that can be opened and closed one handed. The problem with the HF however, is that you need to use both hands to open the lid, something that is challenging to do while while in the car and inconvenience when out hiking or in daily use. This cap pretty much solves the one handed use problem. It easily threaded into the bottle, it's secure and does not leak or drip. The sip cap is easy to use and the spout allows a nice, easy drink. The plastic seems good, but does not seem to be the same quality as the original. But, for $10, I'd simply buy another if it breaks. I have family members who are seeing how this works long term to see if the larger version is worth it for use on the 32 oz size bottles.

Easy to open and seals great. One downside is that it doesn't make it easy to drink from. The mouth is too small for air and you have to waterfall it. I'd prefer a air hole to allow it to flow better. I'd pick a different kind with the same lid though.

A much better lid than anything Hydro Flask currently offers. The lid closes securely without leaking and the carry handle moves out of the way nicely.

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

Great Lid. Works flawlessly.

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

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.

Works very well
