MorlaStandard Size Lid for Hydro Flask Standard Water Bottle and Simple Modern Ascent Bottle.

I looked at this too and thought I’d try it with my H2GO water bottle. The threads looked correct but it didn’t work. Fortunately, I also have a Hydroflask and will use it with that. Easy to carry and drink from. I attached a carabiner to the handle and was able to attach it to my work bag with no leaking.

The color drew me in but the quality has held up compared to other lids I have purchased in the past. I wouldn't say it is 100% leak proof when it isn't standing up, but it's not bad.

This is a great replacement top for my hydro flask with screw off lid. Much easier to use and easy to clean.

I was looking for something to make drinking from my narrow mouth HydroFlask easier without spilling it all over myself because I apparently don’t know how to drink water as an adult :) I liked this item at first, but realized that it leaks (made my entire bag wet) and also leaves an interesting plastic-y smell/taste in my water, which has never been an issue with the original lid. I don’t think I’ll use this item again but I can’t return since I realized it too late lol

Fits on my hydroflask perfectly. I have had it leak through the top a couple times but nothing major.

I have purchased different brands of a similar product. These far outweigh the rest. After heavy use they do start to leak a little - that’s when I replace them. These lasted longer than the original straw lids that come with a Hydro Flask

For Teacher Appreciation day my principal bought all teachers a thermos water bottle with a screw on lid. I like the size for going on my walks, but can't walk and unscrew a lid at the same time. This pop up straw lid was the perfect solution. It even came in a color that coordinated with the school logo. I was sure it wasn't going to fit, but it was a perfect fit with no leaking whatsoever! My only issue with it is that the loop to hold the lid while walking has a sharp edge. I will need to cover it to hold it on my fingers for a lengthy walk. It's uncomfortable having that sharp edge cut into my fingers.

This straw lid is exactly what I was looking for. I love my hydro, but don't like twist a lid off each time I want a drink. I wanted a straw option and came across this lid/straw and decided to try it out.Shipping was quick. I washed the items in my dishwasher and tried it out the next day. WOW, I was so happy it fit the bottle and worked so well. It came with a carabiner, an extra straw and 2 cleaning brushes. Lid/straw comes apart for cleaning and goes back together easily. The handle is great for carrying my hydro. From what I can tell, this lid/straw (when closed) is leak proof. I have turned it upside down and no leaks. I also like that they offer several colors.I am extremely happy with this purchase and will purchase again for additional bottles in my household.

Just what I wanted. Very happy so far - no leaks, no noises.

Wish I had one earlier...
