TOPOKO Straw Lid for Hydro Flask Standard Mouth, Simple Modern Ascent Water Bottle. Improved Design Replacement Cap for 1.91" Mouth Insulated Water Bottle 12 oz, 18 oz, 21 oz, 24 oz. (2 Pack)

This is actually a really good product. We got it because the mouth opening is larger than most. I love this feature. It came with two different types of straws. One a firm plastic and the other silicon. The silicon one is cool, but is made for way too much friction as liquid came up the straw, making it difficult to drink quickly. I ended up switching it out for the plastic one. This straw was a little too long for my bottle so I just cut about an inch of the length off of it. Works great. Has kept up well. Washes easily. Dish washer safe. I've had it for two months now and have no complaints.

The picture shows oval shaped mouth pieces. I had one of these before and they are comfortable and don't leak. The lids delivered have a squared off side and the little hole at the end that leaks even when the lid is down. VERY unhappy.

This is a great addition to a hydro flask so that you don't have to unscrew the top each time you want a drink. Unfortunately if your flask gets knocked to the floor, the top handle is likely to break, at no fault of the product. We were glad that we bought the two pack so we had a replacement! Great purchase!

This is a good product. It came with two spouts, two flexible straws, two plastic straws, the cleaning bushes AND the hook chain. Everything is good about this product. ONLY complaint I have is that the regular plastic straw didn’t fit into my bottle; however the flexible straw fit just fine. Sad part is that I finish my water faster with this product. That just shows how easy it is to use.

These are spectacular! They are super easy to clean so they never get moldy or anything. Love the handle and clip comes in handy too!
