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

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

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

Game changer! The lid that came with my Hydro flask initially was like drinking out of a fire hydrant. And you had to unscrew it every time you wanted to use it.This lid has a little button that allows you to lock the lid so it won't accidentally spill in your bag or car.Just slide the black button down and now it works as a pop top. Just tap it on its lowest setting and now the lid itself pops up so You can take it drink out of your water bottle easily and lightly touch the top of the lid and it seals itself back up quickly.Definitely recommend it. I drink more water now.

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.

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.
