Straw Lid for Hydro flask Wide Mouth Water Bottle 32 oz 40 oz, Top Lids with Straw for Hydroflask Wide Mouth, Replacement Cap Accessories Flip Lid Flex Handle

This is honestly a perfect add for my hydro! It fits right on and I use it about everyday with mo problem. I can see where mold could possibly spawn but that is really up to you and if you keep up with the cleanliness. It doesn't seem wierd on the water bottle it blends right in. Honestly perfect quality and I love using this every time I use my bottle.

Fits my 64 oz hydro flask perfectly. So much cheaper than buying the on brand attachment. I’ve had this product for over a year and I’ve had no issues. Very durable

Fits my Hydro flask perfectly - 32 oz. good quality, black goes with dark blue flask. Leak proof.

This product is very easy to use, open, cand clean. It fits the exact bottles it claims to and I appreciate the extra straw. The suction I'd great. I think the only tiny problems I have is that sometimes when popping open the straw after not using it for a while, water will squirter out of the lid, no matter the position the bottle is held in. Another thing is, when the water in the bottle is low, continuously trying to suck the water will result in a bad plastic taste in your mouth.

Fit like a glove. Comes with straws and a straw cleaner. Pretty cool

I got this hoping it would fit my Coolflask 64oz water bottle and it does perfectly! I believe it would fit most sizes of the CoolFlask bottles that have the wide-mouth opening. No leaks and the straw works perfectly, but can take a little more force than usual if you want to chug water. I just had to cut it to the height of my bottle. This set comes with the lid, two straws, and a straw cleaner, so you get more than you need. Not bad at all for the price!

My son damage his water bottle cover so I went and purchased this and to my surprised it fit. It’s light no leaks how long it will last I don’t know we will see if it can take falls for now I am satisfied. The color is accurate it’s just like the picture

You get tired of using the straw after a while because you after you’ve had it a little while you gotta really try to suck it up because it gets more difficult
