Hitch Bottle
Look at the inside of your bottle lid. You should see a clear silicone gasket inside the bottle lid. If the bottle lid has been through a high temperature dishwasher, it may have become dislodged or come out. Locate it and reinsert into the bottle lid to create an airtight seal when pressed in place. For additional assistance, please email orders@carryhitch.com
Hitch Cup
Look at the underside of your cup lid. You should see a clear silicone gasket around the cup lid. If it has become twisted, adjust as necessary so that the gasket creates a consistent airtight seal when screwed into the cup. For additional assistance, please email orders@carryhitch.com
