Much better!
[This review was collected as part of a promotion.] I love my hydro flasks that I have but I love them so much better now that I don’t have to unscrew the old cap. The straw cap is outsiding!

Straw Cap Is OK
[This review was collected as part of a promotion.] The old pop in-out nozzle flows easier, it is more intuitive to operate, and it allows me to fully empty the flask - all unlike the straw cap.

Leaky Hydro flask top, do not buy!
[This review was collected as part of a promotion.] I am very unhappy with it, it leaks all over the place, and I think I need to return it

You have to have the
[This review was collected as part of a promotion.] You have to have the straw in the perfect position for it to work. Also, based on how they direct you to cut the straw, you end up having to unscrew/take off the top in order to get about the last 6 oz or so of water. Also, it would be nice to have a non-plastic straw.

Go back to pull tops!!!
[This review was collected as part of a promotion.] I don't care for this straw top because it is difficult to get liquid from my bottle once it is down to a certain level. You need to tilt it. Also the straw still tastes like plastic after many washings.

Best Caps for My Hydro Flask Bottles
Love the handle addition! My old ones had none. Both caps are easy to drink from and they are water tight, no leaking, and easy to clean!

Great gift
I bought this for my dad who is constantly on the go. The sleek design allows it to fit into any car, any backpack; any suitcase without a problem. Keeps the water cold all day; great affordable, and usable gift!

Is this supposed to come with a straw? Mine didn’t when I purchased it through another retailer.

Can you just purchase the flex straw itself or do you have to order the entire cap and straw?

How do I get a steady stream of water? Usually when I drink from the straw, I mostly just get air. I tried removing the straw and putting it back in. Do I need to cut the bottom of the straw at an angle?

I recently purchased this straw cap for my 32 oz bottle. It seems like the straw is too long for the bottle, and the cap won’t close all the way unless the straw is bent while closing it? Does this new straw cap not work for the 32 oz bottle?

how do you get this straw lid to work? I mostly get air even though I followed the directions exactly.
