  • Standard Mouth Flex Cap is rated 4.5 out of 5 by 104.
    Rated 5 out of 5 by from Standard Mouth Flex Cap – Black My Flex Cap beverage container came with an old style conventional, hard plastic durable cap. The construction and durability of this beverage container is outstanding. I am very confident should this container drop from six feet to the floor, the cap and body would withstand any leakage or damage. This is a great cap and container for hiking, camping and everyday travel. The integrity of the cap will keep your liquids cold or hot, at the desired temperature for a reasonable amount of time. The cap fits well on all my standard water bottles. It’s very easy to attach, turn and protect your contents. It makes for a good tight fit with no leaks. It takes a little effort to open cap with one hand yet still manageable. Handle is well attached. I give this product a 5-STAR Rating for its design, integrity and construction.

    Rated 5 out of 5 by from No Spills, Icy Cold! The cap came with a matching stainless steel double walled water bottle. The combination of this cap and bottle makes it easy to carry and the cap fits nice and tight. I noticed it never leaks! Having a cap made in this fashion really is helpful in case I drop it or want to stash it in a bag. It helps the bottle keep my icy cold drinks safe and so very cold for hours! I look forward to using it for hot beverages this winter!

    Rated 5 out of 5 by from Great quality I received this item about 2 weeks ago. The Hydro Flask is of great quality and well made. I really like the twist on cap and wide open mouth on the flask. Makes it easy to pour and add ice cubes for cold drinks I highly recommend the Hydro Flask.

    Rated 5 out of 5 by from Ice Cold. Wow! Wow! I ordered the standard size Hydro Flask and we could not be more pleased. Since we live in a very hot climate, having our water remain ice cold is a big deal. You tend to run out of energy easily here, and taking a sip of ice cold water wakes you up. I even tried to check it's claim of staying cold for 24 hours, and it turned out to be true! I purposely left it inside the car of the hottest garage in the free world, mine! It absolutely stayed cold as it claimed. The exterior has a textured feel that isn't slippery at all. It fit easily into the bottle slot of my car. And no kidding, I've seen interior temps of 104 inside. It's vital in Tx to keep hydrated, and to remain ice cold is such a bonus. Awesome water bottle!!

    Rated 5 out of 5 by from Superior Construction to Keep Your Drinks Cold/Hot The Hydroflask needs no introduction and pretty much everyone I know owns one. But I want to stress how this stainless steel bottle is superior to any other bottle I've used when it comes to keeping the temperature of water for a longer period of time. It keeps liquids hot for longer than 12 hours and keeps liquids cold for up to 24 hours. Although the Hydroflask is prone to nicks and dents from rough handling, it won't ever shatter or break on you. The construction is extremely durable and well made. The flex cap that comes with this bottle is also pretty handy, no pun intended. The handle makes it convenient to carry around and the seal is pretty leak-proof. It's also pretty durable and the handle hasn't come off on me yet. I have never had any issues with leakage when it comes to this cap if it's tightened correctly on my Hydroflask. In addition, I love the customization Hydroflask has with their many colors and accessories. Changing out caps for different occasions and situations is convenient and being able to make your own Hydroflask stand out is pretty fun. Cleaning is a little tedious, especially when it comes to the standard mouth Hydroflask. I recommend getting a bottle brush cleaner that fits into the small opening in order to effectively clean the interior of the bottle. For those who want an easier time of cleaning, I would probably recommend the wide mouth bottle to them for easier cleaning access. Overall, Hydroflask is a bottle I use daily and I highly recommend it to anyone who enjoys drinking hot and/or cold water!

    Rated 5 out of 5 by from Durable and leak proof! Love my new 18oz Hydro Flask Flex. The handle is very flexible, very good to carry and durable. It is made sturdy with a stainless steel connector which is also leak proof! The hot liquid stays hot for upto 12 hours and cold stays cold too. Never tried using ice in it though. Overall it is very practical for everyday use , especially during long commutes to work!

    Rated 5 out of 5 by from I LOVE LOVE LOVE this water bottle. This is another great product by Hydroflask. I love the size of the mouth of the bottle. It is big enough to let water flow easily into your mouth but not too big that the water goes all over your face as you go over a bump in the car or riding your bike. The water stays ice cold for longer than you will need to drink it all. It's a great size and the cap is awesome. Easily able to be comfortably carried.

    Rated 5 out of 5 by from Convenient I like this flask because it's very convenient and easy on the go. I like it's size because it's not too big and neither too small. It's easy to take it to work attached with my lunch bag. The best part about this product is that it's insulated and so it keeps hot drinks hot and cold drinks cold, for at least 24 hours, for me. It's not too heavy either when it's full. I like the color and design of this product too. It seems durable as well. The handle is useful to carry it on. I'd definitely recommend this to everyone.

    Rated 5 out of 5 by from Love this bottle! I am absolutely in love with this water bottle! I love the flex cap because it makes it so easy to carry everywhere with me. I can put cold water in the bottle in the morning and it will still be cold in the evening. I can also use it for hot drinks and it will stay hot all day! This bottle also fits perfectly in my bag!

    Rated 5 out of 5 by from Great thermos This is a great thermos/bottle! The construction is heavy duty, but looks great while absolutely incredibly functional. The lid seals so tight without any leaks or spills, and it can easily attach to a lanyard or key chain/ring. It keeps drinks cold for at least ten hours. Very sturdy construction.

    Rated 5 out of 5 by from Fits great The lid fits snug so there is no leakage. The strap is sturdy and is great for clipping onto my bike and backpack. It isn't floppy which is nice, no swinging around smacking into my back or hitting me.

    Rated 5 out of 5 by from great The experiment I did was when you put a very cold liquid in the liquid will actually still stay the same temperature for a long time. The same with hot liquid. I also tried it with room temperature liquid and it actually stood room temperature for a long time. This item is perfect. It actually says what it does. I highly recommend it.

    Rated 5 out of 5 by from I LOVE THIS! Received this today and I LOVE THIS!! The color is gorgeous. It's a metallic gray with a tiny bit of sparkle. It's a perfect size at 18 oz. I love the new lid that HydroFlask has come out with. It's a loop that made of a hard flexible plastic/rubber vs. the old hard plastic solid loop that was hard on the finger if you looped your finger through it. The new loop makes it easy to hang onto and if it's dropped it won't break. I dislike that it's made in China but I hope that begins to change as manufacturing is brought back to the USA. Excellent purchase!

    Rated 5 out of 5 by from Great temperature control! I recently got this item, hoping to have a good quality water bottle for my car commutes. I wanted a bottle that kept water, or other beverages, cold AND that fit in the cup holder in my car. I also wanted one that was leak proof. This bottle and cap does all three! The cap is easy to remove, but at the same time, very secure. There are no leaks when my clumsiness tips the capped bottle! I definitely recommend it!
    Date published: 2019-09-30
    Rated 5 out of 5 by from Great product! Absolutely love this bottle. Nice lid, allows your beverage to flow more freely, the rubber material is soft. It feels solid, high quality, and durable. It kept my water cool in the intense heat; we are at triple digits in summer. Also, no condensation when cold liquids are inside. The handle is great for carrying. No leakage from the lead. Thinking of buying second lid as a backup to my original lid. This way I can alternate to have enough time to dry to avoid the mold.

    Rated 5 out of 5 by from Cold drink I got this container to keep my beverages not thot and cold. After the first time I had used this for a hot beverage I was totally amazed that after 5 hours it was as hot as it was when I put my drink into it! Then when I used it for a cold drink, I could not believe that the ice was still in there after 9 hours! I must say that this beats out all the other name brand containers that I have!

    Rated 5 out of 5 by from Standard Mouth Flex Cap for Hydro Flask I ordered my Mouth flex Cap and received it very quickly. This cap is great for me as I am always on the go and traveling with my Hydro in the airports. It allows me to tuck my flask in my computer bag and easily pull it out secured in my fingers without fear of dropping my flask. I am very excited to have this now and will use it several times daily. If you have the plain cap, upgrade to the mouth flex cap. It is well worth it. I would recommend this to anyone with a hydro flask.
    Date published: 2019-09-30
    Rated 5 out of 5 by from Nice size, sturdy handle. I really like my new 18 Oz Hydro Flask Flex. The handle is very useful and made sturdy with a stainless steel connector. It holds hot and cold pretty good but not as good as claimed. I filled it with coffee in the morning and 12 hours later the coffee was warm. The next day I filled it halfway with ice and then water and 8 hours later the ice had melted. The water was still cold though. I think if I filled it with ice the whole way it might have held. Either way it's a very good bottle and made very well

    Rated 5 out of 5 by from very handy I got the flex cap a week ago and love it, and it is just awesome, it really keeps the cool inside, no drips or leaks, nothing, after a long day of working in the sun, it is nice to still have some ice and water in he canister, really enjoyed it and will use it all seasons long.

    Rated 5 out of 5 by from Excellent product! I was received this products several weeks ago and all I can say is "WOW"! I was so pleasantly surprised at the ease of use and cleaning of the Hydroflask. My drink stayed cold with ice for over 24 hours and was even knocked over at one point and didn't spill a drop! Definitely will be recommending this to friends and family!

    Rated 5 out of 5 by from Keeps my Drinks the Right Temperature Great Thermos! My drinks stay the temperatures I want and since my two biggest drinks are coffee and ice water this thermos is super perfect. I am a mom so I have experienced many cups of unintended cold coffee. I make myself a cup and take a sip and then get busy with the hustle and bustle of the day and then by the time I make it back to my coffee I am drinking it cold. That always stinks, but not now. I just pour my coffee in my thermos and there is no rush in throwing it back as fast as I can just to get a hot cup in. I can come back to my coffee 12 hours later and it's still nice and warm!

    Rated 5 out of 5 by from Works great! Love this cap! It has a flexible carrying handle that doesn’t hurt your hand like some of the others. It seals super well so no leaks.

    Rated 5 out of 5 by from Environmentally conscious I really like this bottle. When it arrived , it came in this new packaging waffle like material and a recyclable bag that you can store it in or recycle it. The handle on the top of the flask is very strong and easy to carry it on the go with you, the metal is sleek stainless and cleans easily. It is a very nice size for me to use to take my nutritional water with me on the go to keep me hydrated. I am supposed to drink 4 to 4 of this size a day. This kept my water cold and my coffee hot. This would be great for all family members to use. It also has s wide mouth so it can be used for things like coffee.

    Rated 5 out of 5 by from Excellent Standard Mouth Flex Bottle! I never noticed this product to be a thermos, or very similar in nature to one. It can readily handle hot and cold fluids. It can keep the fluids at the desired temperature for a long time and after pouring some hot tea into the thermos-like product, it truly did hold its hot temperature for a good long while. I'm not a fan of brand-name thermoses because they are rather expensive for what you get and they cannot regulate their temperature as well. Anyhow, this product works as intended so I was rather ecstatic to see that there are good thermos products. I definitely thought that the size could be improved and the weight of the product could be lowered a bit. But I am not going to deduct any stars because this product works as intended. I think the manufacturer took great strides at making a quality product and it shows. I think this product would hold up well in today's market because people love portable products. You can take your hot or cold liquids with you now and drink to your heart's content. I definitely think that this product was made for me because I am a heavy drinker in general. I always need to drink either hot tea or cold brews. In the end, I love the nature of the product and hope that more products such as these will take effect in the coming future. Thanks!

Definitely would recommend this product fir anyone! Hydro flask is a must for any occasion!

    How does the standard mouth flex cap work? Do you unscrew it every time you want a drink? is there a hinged part that opens in order to get your drink?  Why don't you clearly explain how the "flex" cap works.  Thank you, DC

    You would need to remove the cap every time you want to take a drink.

    Sorry if this a repeat question, I purchased a 24oz insulted in 2014 and ive lost the lid. I got the flask from Amazon and in the description it said it was a narrow mouth bottle. What lid do I need to replace it? I didn't see narrow on the lid page?

    I am missing a cap for my 24 oz narrow (1.5 inch) mouth hydro flask. Can I purchase one of the old style caps?

    What's the difference between this flex cap and the standard cap that would come with the 12-ounce bottle? Thank you.

    Asked by: mlschuer
    The 12 oz standard flask would come with this cap. The 12 oz wide mouth flask would come with the wide mouth flip cap. We used to have the standard loop cap with the 12 oz, but that was discontinued and changed to the standard flex cap.
