Customer Reviews Hydro Flask Standard Mouth Flex Straw Cap

I realized that although I had a hydroflask, I still wasn't drinking enough water on a day to day basis, and I realized it was because I hated having the unscrew and re-screw the cap every time I took a sip (sounds lazy I know). This new cap was a game changer, I can sip water idly while working on tasks at my desk and I am finally drinking enough water. I can still switch back to my regular cap when im going hiking or need to be able to pour water out more easily. Great product, would definitely recommend owning one of each cap style.

Good to have if you have the regular narrow neck water bottle because the original bottle doesn't cover the side so whenever you drink from the bottle, your lips are touching the exposed (germs) area.

The the straw aspect instead of the pull spout we had.

I find it more convenient than the larger Hydro flask. It also fits in most cupholders.

Love Hydro Flask and love this feature! I have several Hydro flasks and it fits them all!

Complements the bottle nicely! Makes drinking that much easier!

Love this non-leak top. Great & convenient handle to carry

Love my purple hydro flask! I take it to work and to go exercising! The flex straw option works perfect!

I am SO excited that you all finally created a straw top for the standard mouth bottles. I no longer have to turn the bottle upside down to drink from it.

Happy with this wonderful cap since my recent purchase.

My kids love their flip straw lid- and it's making water breaks a more frequent event in their day. Plus, customer service was over and above today's standards- a real person answered my email when I accidentally ordered the wrong lids. Even though it was my fault, my truly desired product was sent free of charge

Very nice cap. Easy to clean and works well. Very durable.

The straw lids for the wide mouth bottles now make these my go to water bottles. In the car, the straw lid makes it possible to drink without tipping the bottle.

Great, easy to use, and completely spill proof. A wonderful addition to my 24oz hydroflask.

Does not leak! That is the best part of this product. I believe they should come with this lid.

Cap is easy to be install; sturdy and functions as described.

This is the best option available yet! My daughter loves the flex straw cap. No more getting drenched in water.

Works as advertised. Read someone complaining about being difficult to decipher which way it flips open because it is a little symmetrical -- ehh if you're an adult you'll figure it out. However, I guess they could have added a marking/logo of some sort just to differentiate the two sides. You'll survive.

Excellent and helps me get more water in daily! Perfect !

Great lid! Fits snuggly so there's no leaking. Easy to drink on the go. Sealed to help keep on the cool too.

My whole family loves the new sip lid for the standard size bottles!

Love the top. It's so convenient to use without having to worry about my drink spilling. I love the attached handle also.

I needed a sip straw for a new bottle. It works great.

The only unfortunate part is the instructions telling you to cut the straw shorter than it should be. Following the directions leave you with about 1" away from the bottom of the bottle so you cannot get every drop. Fortunately there is a second straw, but expensive for having one of the straws be useless.

Love it! It does not leak, great choice for bottles that have a standard mouth. Better alternative than sport cap. Fewer moving parts, less chance for breakage.
