IRON °FLASKFlip Lid for Wide Mouth Insulated Sports Water Bottles, Wide Mouth, BPA Free, 2 Lids

These caps fit perfectly on a water bottle I picked up at a gift shop in Hawaii. There was no brand name on the bottle, but I measured the bottle diameter and chose these. So in a way I got lucky, but these seal tightly and the quality seems excellent. The original cap broke when I dropped the open bottle on asphalt, chipping off a corner of the fliptop. It's a nice insulated bottle, so I'm delighted to find this replacement.

With how often I drop my water bottle I bought these to replace the lids I break. I've dropped my bottle with these lids on it and have yet to break one. Very durable, nicely designed, easy to use and clean, great value for the money.

Our household loves all our Iron Flask insulated cold and hot drink carrier cups... The quality of Iron Flask is top notch and worth every penny. We bought these as an accesory to our flasks and work exactly as described.

These are perfect replacements for the Iron Flasks. Four stars because I hate that these flip top lids don’t last long! Please address this Iron Flask!

I have a tendency to drop these bottles. I use them all the time so I was thrilled to be able to replace just the lid and not the whole bottle.

Love these! I go through kids regularly as I tend to drop my water bottle too often. These have been great replacements.

Works great, no spill. Love the option to switch lids

The mouth cover piece was a sticky material that was very difficult to clean
