Top Souls Wide Mouth Straw Lid and Silicone Boot fit for Hydro Flask and Most Sports Water Bottles from 12-40 oz, with 2 Straws and 2 Brushes in 1 Set Full Value Pack Medium

This size did not work for my bottle that I already had. I was trying to replace a piece that had worn out but it was too big and didn't work.

I have a 32 oz watermelon hydro flask and the watermelon color matches perfectly. Zero leaking from the lid. Both lid and base fits perfectly. I ordered the medium size.

I love the silicone boot. It protects a crack I already got in these stinkin' cute epoxy bottles, haha! Good peace of mind that it will help in the future. The straw was good, but the lid leaked. I need to check out the seal and hope it was just something in the way. Boot is great, though!

This leaks like crazy, it also doesn’t fit nicely as my regular lid which is a bummer but it didn’t matter it’s missing a plug shown in first picture. I can return it but it’s like 15miles to return & gas isn’t cheap right now. I will just keep it anyways since I like the silicone bottom piece! Keeps my bottle from banging around when placed on the table/counter or wherever.

The lid would fit my water bottle, but the boot came ripped, so was unusable. The boot silicone seemed a little thin and therefore could become easily ripped. I think If the item was packaged better it might not have gotten damaged.
