Best Travel Mug Idea Yet: Cuppow (Plus Cozy)

Anyone who’s been to our house knows how much we like a simple Mason jar.

We do have an actual set of drinking glasses. They even match. But we prefer to drink our water, juice, milk and margaritas out of regular canning jars, especially the jelly-sized ones.

They’re easy to clean, can hold hot or cold drinks, make great non-leaking vinaigrette jars, and are super durable. We’ve yet to break a single one.

We’re clearly not the only ones to appreciate a good Mason jar.

A couple of artists in Massachusetts have come up with an innovative way to turn a wide-mouthed canning jar into an eco-friendly, sip-on-the-go travel mug they call Cuppow ($7.99). It’s so simple it’s brilliant.

I saw some concerns about heat transfer. Canning jars can hold scalding liquids without a single crack. But most folks don’t touch the glass until they cool off.

Not to worry. There seems to be a solution to this problem: knitted Mason jar cozies at Etsy.
