IRON °FLASK Flex Straw Lid for Wide Mouth Insulated Sports Water Bottles, Simple BPA Free, 2 Lids, 4 Straws, 2 Cleaning Brushes (Aquamarine)

Needed a replacement for my straw lid after the strap broke and night these. They fit the 40z perfectly and so far holding up well. 2 lids, straws and a brush for $10 is a great value! No issues with the product as it works as intended and the seems are lined up for easy attachment to the bottle

Works great

These perfectly fit multiple old bottles I've gathered in the past few years. My kids love these too. Revived their favorite bottle (25oz standard lid size) with new straw top. Also fits my 40oz thermos bottles.

These lids match my iron fat flask, exactly and I love them. They fit the lids perfectly. Something I don’t really love about them is that the straws come in the longest length possible and it’s not exactly easy to figure out how long to make the straws. As an example, I have a 40 ounce and a 20 ounce water bottle. And obviously these are made for the larger ones and you can cut them down if you want. But if you do it improperly, the straws are pretty useless. A stencil that shows the lengths would be awesome.

Works very well!.

I got this set of lids to replace the one that came with my iron flask. Unfortunately I dropped and broke that lid so it leaked constantly. So far this set is perfect and doesn't leak at all.

This review would have been 5 stars but one of the lids just broke. I've only had the lid a fee months and all of a sudden, the plastic on the lid that was attached to the silicone handle just broke away. It didn't get dropped or anything. I just reached for it this morning, where it was sitting on my bedside table, where it had been all night, and it was just broken. I'm glad there's a second one, at least, but it should have lasted more than a few months. The set itself is great, the lids are easy to clean, especially with the brush they include. I'm disappointed.

I ordered this to replace the broken one that came with my ironflask. This lid is even better than the original. I like that the carrying loop is now a moveable silicone instead of the fixed hard plastic on the original, PLUS you get 2!
