From BRUMATE:

Hate warm beer? We do too. That's why we created the Hopsulator TRíO, the most versatile can-cooler in the world. It fits all your favorite 16oz craft cans, comes with an adapter for 12oz cans, and with one quick switch turns into a 16oz pint glass. There's a reason we patented it.

• Patented 3-in-1 design
• 20x Colder than standard can-coolers
• Keeps your drink at the perfect temperature
• Glass-free zone friendly
• No condensation
• Stainless steel insulated BevGuard tech
