Customer Reviews Hydro Flask Standard Mouth Flex Straw Cap

Great product, great customer service , Great shipping.

Best for keeping water cold or hot.

The instructions on how to cut the straw made it way too short. So I cut the 2nd straw the way that made more sense to me- it's better but still not great. I need something I can easily drink from while I'm riding my bike and this is a better solution than the screw off top but still not great.

r service is excellent & your guarantee is beyond reproach - the best there is! Thank you! I am so glad I purchased your product!

Very good

Has strong taste of rubberick

Happy wife happy life

The instructions say to cut off 1". That is too much on the 24 oz bottle.

Great idea but I have not been able to use ice cubes the way I could with my old cap. I also cant get the last bit of water out through the straw.

Works great so far

Theres a lot of air bubbles as I drink

Does not have a smooth draw which makes it difficult when hiking or exercising

This cap provides for leakproof drinking with or without a straw. It's great for one handed drinking while driving.

Awesome.

I was expecting this flask to keep things cold, but was surprised how well it holds carbonation! Fizzy till the end of the drink. Love it!

Much better design

I purchased this item to replay my cap, but I was thinking the straw would not require quite the effort. Its good and works just fine; it seems a bit small emerging front he mouthpiece. Nothing wrong with it, and the cap seals perfectly. One suggestion: cut the straw long and work down to the proper length. I think I cut mine too short and always have water left in the bottom that I cannot reach w/ my straw.

I didnt like the cap that came with my standard size drink bottle because it leaked unless it was upright. This flex straw cap can be put on its side without leaking.

Ive purchased so may of these wonderful bottles I have lost count. EVERYONE in my family has one!

Absolutely love my new cup.just really sad how easily the lid pops off if it gets bumped or jostled. As long as it stays on my desk its okay..except when it gets bumped into..thankful was able to save my computer before it got to wet.

Great for kids

Excellent. Thank you!

I am not a straw person and it works fine without the straw

I like the flask, but I do not like the flex straw cap because it will not pick up the last of the liquid in the bottom of the flask even though I cut the straw according to the directions.
