Silicone Water Bottle Cap (6 Pack)

The dishwasher-safe part sold me, because I’ve ruined too many plastic lids in the top rack. These fit snugly over the bottle mouth and haven’t stretched out after a week of daily use, which is exactly what I needed for my kids’ cups.

I was skeptical about silicone caps fitting my various bottles, but these stretched over every one without tearing. Tossed them in the dishwasher after a week of camping and they came out spotless, no warping or weird smells.

The 6-pack covers everything from my kids' bottles to my own, and the multicolor set makes it easy to tell whose is whose. Threw them in the dishwasher a few times now and they’ve held up perfectly, no warping or weird smells.
