Customer Reviews Hydro Flask Wide Mouth Flex Sip Lid

Love the Flex Sip top, its my new favorite top to use on my Hydro Flask. I would 100% recommend it, leak proof is a big thing for me. You definitely get what you payed for ;) If there were more stars I'd give more than 5.

Very high quality drinking lid. Parts fit together with extreme accuracy.

Simple, intuitive. High flow when fully open no leaks when closed. Easy to take apart to clean and just as easy to reassemble, did not even need to look up how to do it. Only nitpick I have is that when you're done drinking make sure to get all the water in the little pocket because sometimes there's a tiny amount that stays. But so far hasn't broken and doesn't feel like it's going to anytime soon.

This lid fit perfectly on my hydro flask. The lid sealed as it should and did not leak. Did its job in keeping my drink very cold. There is no complaints from me. A for sure must buy product for your hydro flask needs

Great for hot drinks, the lid is easy to use and easy to clean

I bought one for myself since I drink the most water in my family and loved it so much I bought one for everyone! It's so easy to use and very kid friendly.

I bought this as a replacement for the old version of the lid that leaked. This new lid is 100% better and I love it so much. No leaking!

I bought this to replace the lid on my year old flask. It's much better the the flip up one it had. Very happy.

Easy to disassemble and clean, and does not leak! The only thing that would make it even better is if they sold the interior "washer" separately, since I can imagine it tearing or breaking eventually, while everything else will last a long time I think!

Great lid. Convenient handle. When it falls over, it doesn't leak.

One of the lids had black marks inside dont know what it is

I like this lid better than any I have had before! It seals well and is easy to use. My favorite feature is that it is easy to clean! Just took one time to learn the process. Definitely not going to have any mold hiding on this one! Highly recommend the lid!

I bought this flex lid for my honey and he loves it. The flask keeps his iced tea cold and he is in good spirits from 10 to 4 with the twist flew lid. Thank you!

I like that I don't have to unscrew the cap off my flask in order to drink.

This lid makes a lot easier to have a drink while walking or exercising. It also closes completely to prevent spilling.

It seals better than the old flip-cover model. (No drips if it falls over.) And a nice carry handle too.

easy to clean and better for holding when walking around

This lid is exquisitely engineered: from the twist lock feature to the high volume flow rate when drinking, I am impressed.

This makes the Hydro Flask so much more convenient to use. When using this lid, when I'm working, twisting the top open and taking a drink means the chance of spilling my drink is reduced and was the only concern I had with this product. As you can understand, the wide mouth helps quench your thirst faster, but could be a problem for electronics that I spilled a liquid on.

Works good for my dad. He wanted an easy lid to grab a sip of water since his work always has him on the go and he didn't want to bother with having to remove and put a lid back on every time he's thirsty.

I bought it last month and I love it. I bought 2 one for me and one for my son that he use it for soccer.

This is exactly what I needed for my workouts in the gym. Very easy to open and get a quick drink. Got tired of unscrewing the old lid and drinking from the bottle. This lid was just what I was waiting for. Great addition ... love the small things in life to make things simpler. Also, very well made and easy to take apart to clean thoroughly. Mahalos.

So easy to take apart and clean! Love it! The handle doesn't get in the way and it's nice and solid

I use this to drink water and I find that I drink so much more of it with this top on! Useful when you want to sip all day long.

I have an old coffee mug with the flip that started leaking recently. I have quite the collection of Hydro flasks and this was my first purchase probably about 10 years ago. So it has been used and used over the years. So I contacted customer service and explained the situation with the lead. Well let me tell you, the Lid warranty is for real. I received a response from customer service very promptly and they are replacing my lid with the new upgraded model no questions asked, no hassle and at no cost (not even shipping). It's good to know that you have a company that stands behind their products, this isn't always the case in today's society. Thanks for everything Hydro flask and keep up the great work! I'm a loyal customer for life!!
