We understand that water bottle caps sometimes get lost or go missing. These water bottle replacement caps are for use with both the 6oz (177ml) and 11oz (325ml) FlipBelt Arc water bottles. Purchase bottle cap replacements online.
NB: ARC Water Bottle Caps are not compatible with the pop-top style bottles made pre-2022. They have a larger circumference (better water flow). You can purchase the original Pop-Top style lids online.
