The Hydro Flip Lid is the instant conversion kit for Wide Mouth Hydro Flasks. Coffee, tea and other hot beverages are just a flip away and consuming hot beverages on the go is as easy as can be.
Like all Hydro Flask caps, the Hydro Flip is made out of 100% recyclable PP5 and is BPA-free. The lid features a flip-top opening with rubber stopper to plug the opening and help prevent spills when not in use. Please note that the Hydro Flip Lid is not leak proof
The Hydro Flip is now available in new colors, too, as part of the Hydro Splash Line! Hydro Splash colors include Electric Blue, Banana Yellow, Limeade and Perfect Purple.
The Hydro Flip lid fits our 18 oz Wide Mouth, 40 oz and 64 oz flasks. Please note that the Hydro Flip lid does not fit on the older style Wide Mouth flasks. To find out which style flask you have and whether the Hydro Flip will fit yours, check out the Hydro Flip Fit Guide.

This lid is so convenient. I've had no problem with leaking or anything like that but it does not help the flask keep the liquids cold nor hot, like the flat lid does.

My flip lid leaked when I first got it but upon the advice of a friend who had a similar problem, I took a chopstick (a cotton swab or similar object will also work) and ran it around the rubber gasket inside the lid to press it in more snugly. The lid stopped leaking and I have had no further problems with it many months later. Now that it no longer leaks, I really like it.

One of the best lids out there for my coffee. No issue with leaks and it flows fast! I was looking for a coffee cup that kept my coffee hot and this one does. Thanks

I have one of these lids that came with the coffee wide mouth bottle. Fits great and the mouth with the lid open is perfect BUT it leaks like crazy. Dont you dare tip it over at all or even think about shaking it unless you wanna wear your beverage. Now my coffee bottle is just collecting dusk in the cabinet since I dont usually enjoy coffee stains on my clothes. HUGE disappointment!

The flip-top lid is super convenient and I prefer it to any screw top lid. However, this plastic isn't the most durable - I've broken at least 3 of these in the last few months just from dropping them on the ground. I'll keep using these bc they are the most convenient but I really wish they'd make a flip-top lid that matched the quality of the flask itself.

The lid is very convenient, good concept. However completely defeats the purpose of a Hydro Flask. The bottles are PHENOMENAL: keep hot for 8+ in bellow 0, ice cold for 12+ if left in direct scorching heat. The smaller the Mouth opening is the better insulation. Now, this Wide Mouth bottle lid does not fit & screw INSIDE the mouth opening like all of the original caps. Instead it screws on the outside and it has a thin plastic layer, that as any Hydro Flask owner will agree is simply convenient, but the lack of substance in the design will have your tea/coffee lukewarm in about 2h indoor temp and ice cubes simply melt by the minute.

I've had my hydroflask for about a month now and i've literally shattered 3 caps from dropping it from a height of no more than a foot or two. Waste of money.

Pretty much leak proof... and the great thing it fits my Klean Kanteen...I like the style of their bottles but hate their twist lid coffee lid and the fact that the hydro flask lids fit saves me from buying a whole new flask.

Are you ever going to have the wide mouth flip lid back in stock? It has been out for months this would be a great stocking stuffer

My kiddos love these tops. I know they aren't "leakproof" but if you follow the thread to tighten - you'll never had a leak. we've used them for a few months now and they're still perfect. Try it.

Bought this to eliminate the screw top removal for easy drinking while working or driving. I bought the 40oz Hydro Flash 40-Ounce Insulated Stainless Steel Drinking Bottle and it does work but with the new designs on the market that are push button to drink while keeping fully sealed by Contigo is design Hydro Flask needs. ***PRO's** *Tight seal *Fits Easily *Price *Shipping (fast and free) *EASY to clean *Works well with Hot and Cold **Cons** *2 hand operation *Design needs update

I like this top better than the straw type. Its very easy to drink from and has a very positive seal when closed which does not leak if the bottle is laid on its side.

Free shipping was super fast (I don't have Prime). I ordered it on Monday afternoon and received it on Wednesday in the mail. This cap works just as I had hoped. It has a smallish hole which prevents splashes while drinking. It is leak-proof as long as the gasket in the cap is seated properly. I'm really happy with this purchase.

I live Az so you carry water all the time. I bought a large insulated bottle with a wide mouth so I could add ice , it was nice if you didn't mind a bath every time you take a drink. This lid tamed the beast an made getting a cold drink while driving down the road a pleasure .

The flip cap is definitely the way to go with the wide mouth Hydro Flask. It makes it easy to get a drink without having to take the top off. The seal is very tight, so that if the flask rolls over, nothing spills out. The only negative I had was that after trying out the flask and lid with my coffee, I had a really hard time getting the smell of coffee off of the lid. I even tried taking out the seal and using bleach water, but I could still smell the coffee. So if you are going to use your flask for both, I would be tempted to have 2 lids and mark one of them coffee only.

I have used the Kleen Kanteen bottles for many years and have used their sip lids but have always hated the rotating closure mechanism. This Hydro Flask lid is so much simpler and easier to clean. It also gives a far better liquid flow compared to the Kleen Kanteen one. The fluid will flow out almost as fast as you can drink it. This is not a leak proof lid but it seals very well, again, far better than the Kleen Kanteen lid. Overall this is a great lid unless if you need complete leak proofness. I originally starting using this brand because of the larger bottle sizes available but will probably switch over even my small bottles because of this lid.

Just received the new flip lid for my 40oz wide mouth bottle, and it's perfect. I carry this bottle to work every day and have ice cold water all day. The reason my title said "The Perfect Lid...almost" is because the strap on the screw on lid was a perfect handle to carry the bottle by. If you guys could come up with a ring/handle that would work in conjunction with the flip lid, you would have The Perfect Lid! I currently have (2) 21oz bottles, (1) 40oz bottle, (1) 64oz Growler, and (1) 12oz food flask, love them all. They may seem expensive, but in reality they are a great value!
