EIPOSAU Auto Flip Lid for Hydro Flask Standard Mouth Bottle, Spout lid for Iron Flask, Fits for Simple Modern and Most Brands, Replacement Lid with Button Lock, Black

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.

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.

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.

Very surprised when I just got them, the delivery came early. Doesn’t have a smell you would think. Went to test them out by pouring water in to my iron flask narrow mouth and shaking it left-right and upside down like crazy. No water leaked. There is a locking mechanism that allows you to secure the button so you don’t spill them by accident if you put them in ur backpack and such. Something small I noticed is the handle of this thing is bigger than what im used to, I know a lot of handles only capable of holding two fingers maximum without feeling uncomfortable. This there you can put all 4 fingers and carry it comfortably and it’s better you have a bigger bottle. Now I haven’t test it’s how durable is the handle that will have to leave it for now. However the built quality of the whole things seems robust enough and the color looks great, nice and sleek. Can’t wait to put this to the test for my daily wear. Great value for the money!
