    Rated 5 out of 5 by from YAY Hydroflask !!! The Hydroflask standard mouth Flex Cap is the bomb! Keeps my Hydroflask handy for both hot and cold portable refreshment!

    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 Awesome Water Bottle! Was not sure I would like this bottle. I have become very addicted to my yetti. This is amazing. Ice will last forever! I think it was about 13 hours since I made my water bottle and I grabbed my bottle and it was still icy and cold! Handy to carry this by the top and its slender so it fits really nicely in my purse!

    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!

    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.

    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!

  • Will this cap fit 25 oz Wine Bottle?

    Asked by: Sue95
    Yes, the Standard Mouth Flex Cap will fit the 25oz Wine Bottles.

    Our 21 oz, insulated flasks are our favs but over time, water got into the caps and the standard rubber ring developed mold.  Took it apart & cleaned it, but the seal is discolored & water is difficult to remove from cap.  Will new design solve this?

    Is this lid leak proof?

    Asked by: JordanK
    The flex cap is more of the leak proof option because it has no openings in the caps.

    What materials are the cap and strap made of? My girlfriend has an allergy to certain rubber and latex. She has a small rash on her hand that we're afraid is coming from holding the lid to her flask.

    Asked by: Maja88
    All of our caps are made out of BPA/BPS free polypropylene. All Hydro Flask products are certified by the US Consumer Product Safety Commission to meet or exceed government regulations. The straws for our Straw Lid are made out of low density, BPA/BPS free polyethylene.
