Customer Reviews Hydro Flask Standard Mouth Flex Straw Cap

There are few products that come around where you know that product is at a whole different level, whether its the engineering like a Kuat bike rack or technology in an Apple Watch. Hydro Flask is in the category. They have a bottle for every situation and tops for how you like to drink. Between my wife and I, we have at least 10, one size and style for morning coffee while driving, one size for walking, one size for work like the 32 oz. They have made cleaning so easy also. They are far and away the best on the market in this space and we know cause we have 5 different brands of water bottles in a box in the garage collecting dust.

Is exactly as designed. Keeps fluids cool for a long time.

Same as the other comment

Definitely worth it! It works great and I appreciate the product

Hi

Haven't had a chance to try them yet but they look like just what I had in mind

Customer service was on point and very professional

Love all my hydro flasks! The best

My daughter loves her new water bottle. It is also easy to clean. We will be buying more.

Attractive functional and it does keep it cold!

Awesome customer service. I misplaced a part of the cap and you replaced it for me without charge. Otherwise the bottle was destined for the recycling bin.

I love my new bottle. The ice lasts more than 24 hours. Water stays cold. I take my bottle everywhere. The hot yoga studio doesn't affect the cold water. I will definitely purchase more in the near future.

It works like a dream!

So happy to have found a cap that doesn't leak. Other Hydro Flask caps have leaked, so I am excited about this one. My only complaint is that it's hard to tell which way it will flip open. I feel like that should be marked somehow.

The sipping spout should be soft and allow more flow and easy to clean. If its not completely closed into position it does leak.

The standard mouth flex straw cap was perfect for my new Hydro Flask. It makes it easy to drink and no spells. Very impressed with that. It actually makes me drink more water throughout the day.

I bought this because I like the caps with straws. My bottle is a pretty blue and the red stripe on this does not go at all. Why not make it just black? The red ruins the look.

You do have to prep the straw to the bottle height. I'm glad it came with 2 straws, I made the first a bit too short and couldn't slurp the last of the water.

Make sure the part you drink out of is all the way back. Many times I go to drink and find that it doesn't work but it's due to that.

Allows use of hydro flask anywhere. No need to figure out "what to do with cap" while using it. Great addition.

Love having the straw but trimming it to length was not as easy as anticipated

i love it for sports drinks. easy to clean. i wish the flow rate were higher, but that's a tradeoff of it being leakproof, i guess

I appreciate it doesn't leak. Easy to open. The straw is simple to install. I am having a harder time getting use to the effort to drink with it coming from the old standard one you tip the bottle and get a good gulp from.

I don't like that the stew needs to be cut. My straw was cut too short by accident. My partner is not a straw cutter. It's really too bad.

This is the straw cap for the Hydro flask I have. This is a nice cap although sometimes it is hard to suck through the straw. After a few uses air gets in the straw and you have to readjust it. It is difficult to set up to make sure that it is working right. But overall it works fine. The dishwasher safe so that's nice
