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

Perfect fit for my 21oz Hydro flask! Seals nicely with no leaks. Love the push button flip top lid and the added lid slider lock protection is a great feature. It doesn't taste weird, is dishwasher friendly (haven't used dishwasher heat dry), and has the same appearance features (black finish, soft rubber carry loop w/silver grommet) as my original lid. The pour spout opening solved my problem of wearing more of my drink than actually drinking. Would and will buy this again!

We bought white and black for our Hydroflask bottles. Perfect fit and easy to use, very durable. Washes good in a dishwasher.

This works great with the tall thin 24 oz hydro flask bottle. No leaks! Love that it has a lock on the flip top and carrying handle.

Have used these for about a month, now, and find them to be a perfect fit as a replacement lid for my Iron Flask water bottles. Personally, I find the lock button opening easy to use, though it seems like others are confused by it. It is a two position system that is meant to keep the bottle locked when it's not in use. To engage or disengage the lock, you simply slide the button vertically up or down. The lock is engaged when up and disengaged when slid down. When disengaged, the button then pivots on a fulcrum. This let's the lid flip open on its spring-powered hinge for easy opening. If you weren't aware of how these work, I could see how you might think that the tops are broken or defective. The build quality seems adequate, though not especially durable, and they have not leaked at all with regular use. Given this, they might be priced just a couple of dollars too high for what they are. Still, they are convenient and easy to clean, though I can't speak to the long term use and reliability of these tops. They are, however, performing well after moderate use for the past month.

Quick delivery. Fits great and seems well made.

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.

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 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.

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.

the cover is fragile and breaks easily. this is our 4th one within a year.

Works very well
