Rambler® Insulated Food Jars FAQs

How do I open the MagVent lid?

The MagVent Lid vents as it opens, which causes a hard stop to occur after the first quarter turn counterclockwise. To remove fully, just keep turning past this point until the lid comes off.

What do I do if the Magvent lid gets stuck?

If the lower gray piece of the lid is stuck in the jar, you likely pulled the top piece off too early. Screw the top lid back on until it's fully closed. Then, unscrew the lid counterclockwise, past the resistance, until both pieces come off together.

If the issue persists, please contact YETI at yeti.com/contact-us for assistance. Do not force the lid open with tools of any kind.
