Straw Lid for Hydro Flask Standard Mouth Water Bottle 18 21 24oz, Flexible Handle Leak Proof Sports Cap Fit for Hydroflask, Flip Straw Top Lids (Black(2Pack))

This fit both of my hydro flask bottles, though I did trim the straw on one since the bottle was shorter—the straw barely fit in the taller bottle, but it does the natural bend to reach to the last drops. It’s easy to install, use, and clean, and has not leaked. I noticed that it also does not allow me to drink any water unless the spout is completely open, which was annoying at first but a nice protective feature. I would recommend this!

This is a wonderful cap to replace the stock Hydro Flask one. I like the straw feature that enables me to drive and drink water without having to tip a water bottle up in front of me while keeping my eyes on the road. This is well-constructed and great for me and my wife to use on each of our bottles.

Fits my hydro flask perfectly and doesn’t leak, got it so I wouldn’t make a mess at the gym when drinking water lol

My son (6) drops his water bottle on a daily basis and destroyed both of these lids in short order. All it takes is for the bottle to hit the floor head-on and the tab breaks off immediately, rendering the lid inoperable for small hands. Otherwise, the lids are of great quality. I would recommend them for responsible adult use, but they're a waste of money if you plan to use them for a kid's bottle.

I hadn't used my hydroflask in a while because tipping it to drink from was cumbersome and I kept reaching for a tumbler with a straw. This lid fits perfectly and my favorite thermos is used daily again. The flip down is secure and prevents leaks. I'm so glad I found this lid option when I considering a pricey replacement thermos cup.

I bought a hydro flask but was not keen on having to tip the bottle up to get water. This flip top option allows me to sip while driving on long road trips without obscuring my vision.

Love it

The straws are extremely long and do not fit my 21 oz water bottle.

This fit perfectly on my klean kanteen classic bottles replacing the old sports cap. Seem pretty solid with no leaks.

Very good cap for the standard hydroflask. The straw is a little long but it can be easily cut and adjusted. It even works without the cap. Very much needed for someone who uses their water bottle a lot! No leaks at all.

Like the ease of use over opening the cap to drink from.

Malheureusement, contrairement au bouchon original venant avec la bouteille, ce bouchon n'est pas étanche! En effet, je ne peux pas laisser ma bouteille de côté dans mon sac sinon mes choses seront toutes mouillées. Sur une note plus positive, le bouchon fonctionne très bien et il est facile à nettoyer!

These fit well and don’t leak. Overall good purchase.
