No leaks
I love the hydroflask wide mouth flex sip lid. It’s perfect for on the go drinking. There are no leaks and it is easy to wash. I really appreciate how hydroflask gives you more than one lid option. My kids can easily drink out of it.

Easy to clean
I got this sip lid to replace the original lid that came with our 20 oz hydro flask. I was glad to find that the lid pieces come apart making for easy cleaning. Some lids can be difficult to properly clean, but this one simply unscrews for a good wash.

Easy drinking
This lid fits my 20oz bottle perfectly. I like how with a simple twist I can open it. It makes drinking easier. It is easy to clean this just twist it off and wash it. This lid is probably one of my favories. I no longer have to remove it each time I want to drink. Just simply twist and open.

Perfect Addition!
We recently got a Hydro Flask 20 oz Wide Mouth and wanted to have a different lid. TheMy Review for Hydro Flask Wide Mouth Flex Sip™ Lid is great! You don't need to continually take the lid off to get a drink! My son loves it for drinks at school! A must have if you love Hydro Flask!

Great features
The main purpose for this lid is to drink hot beverage easier so you dont have to open and close the regular lid for drinking. It's easy to use, put together and pull apart for cleaning. Lightweight and no spill, no leakage guaranteed while using. Good product

Great!
We love our Hydro Flask wide mouth flex sip lid! Super great quality and no spills or leaks! I love that you just twist the top to open and close because that makes it easy for kids. And there is a handle attached for easy carry. Hydro Flask is the best and worth the money!

Perfect lid for on-the-go!
I had the opportunity to utilize the Hydro Flask Wide Mouth Flex Sip Lid with my 20 oz Hydro Flask Wide Mouth Tumbler. As a busy mom, always on-the-go, I absolutely love this lid option for drinking my coffee and tea in the car, while shopping or when at an event! This lid fits securely on my tumbler and features an easy-twist option for opening and closing the sipping spout. I love that the red line indicator makes it simple to see that my tumbler is sealed. I have had no issues with leaking, and love how hot my beverages remain, even hours after pouring. The easy-hold handle is a huge bonus for me, as it makes carrying my tumbler easier when I have other items (or people) in tow. The Hydro Flask brand holds true to its high-quality promise in every way!

Perfect addition to your hydro flask!
This makes your hydro flask even better! I love the ease of not having to take the lid all the way off to take a drink! I also LOVE how easy it is to take apart to be able to really clean it too! The handle makes for easy carrying which is nice too! Even if you leave it open it keeps ice frozen for hours!

Great addition
I got my new wide mouth drinking lid when I git my new hydro flask being very optimistic about how it would play a role in my everyday usage and I have to honestly say it works well for different situations especially when. On the go everyday walking I don't have to worry about spilling my beverage when walking and it simply twist on so it's not hard to innstall

Perfect for taking on a workout
I love having this option for a wide mouth flex sip lid for my hydro flask. I have found it to be very handy when working out. I can get a drink from the opening without taking off the whole lid. This was a perfect match for me and my hydro flask. Great quality at a excellent value. I would definitely recommend it to everyone that has a hydro flask.

Perfect companion
The flex sip lid that goes with my hydro flask makes it much easier to drink any beverage when you are on the go. The design secures a no-drip sip (my words not theirs) that is easy and convenient, along with looking really good. I think this product is very well thought out for anyone needing a solution to carrying hot or cold liquids.

Loved the lid
I was chosen to receive this product in an exchange for an honest review. I loved the wide mouth lid because it was much more convenient to just turn the lid when ready to sip and close when done to prevent spills. I prefer this lid rather than the spin top that the flask comes with. I have having to remove the lid every time I have to take a sip so the wide mouth flex lid was very appreciated! Overall this product was great and I recommend it!

Great lid!
Love this extra lid! It is very easy to use. The Flex Sip lid definitely makes sipping easy and spill proof. I prefer sipping my drinks rather than drinking straight out of the container! So this is the better lid for me!

Finally! Easy to Clean!
Where has this sip lid been my entire life?! I find it hard to actually clean any sip lid; therefore hesitate to use reusable sip lids due to worries about bacteria build-up. This Hydro Flask Wide Mouth Flex Sip Lid is the perfect solution. I use it for my workouts everyday now. The lid comes apart into pieces so that I can easily make sure that it is all the way clean. Taking it apart and putting it back together takes a little bit of learning; fortunately the lid is marked with directions on how to do it. No spills will happen when the red indicator is showing through the top of lid. It will definitely spill if it gets knocked over and isn't turned shut. Highly recommend for your Hydro Flask.

Wonderful cap!
Easy to use, easy to clean, handy carry strap, has a red dot indicator so I don't have to guess whether it's open / closed. It's a vast improvement over their Hydro Flip cap which easily breaks when dropped. Fits my similarly-sized Klean Kanteen thermoses. I also have Klean Kanteen's Cafe Cap 2.0. It too is leakproof but it has 5 pieces to take apart for cleaning; this one only has 4. I've only had this for one day so I don't know how durable or leakproof it will be in the long run. HydroFlask's website does not offer replacement gaskets; hope they will in future.

The Best
I bought this lid for me and my girlfriend about a year ago when it was released and it is the BEST thing that hydro flask has created! I don’t personally like drinking out of the wide mouth openly because I’m clumsy and it spills all over me so this lid is even a great replacement for just drinking water through! Definitely a thumbs up!

When Drinking your Coffee how do you know it's not to Hot?? With the Flexcap
We apologize for the delayed response.
Our best suggestion would be to let the flask sit open for a bit and then test it before you put the lid on.
