A durable, double-walled vessel engineered to minimize heat exchange, keeping drinks hot or cold for hours. Ideal for travelers, students, and outdoor enthusiasts.

Key Features

• Double-wall construction: Inner vessel holds the liquid; outer shell provides an insulating air gap.
• Vacuum insulation: Evacuated space between walls dramatically reduces heat transfer by conduction and convection.
• Reflective interior: Polished surface minimizes radiant heat loss.
• Secure lid: Tight seal helps prevent spills and reduces heat loss when closed.
• Materials: Typically stainless steel for the inner vessel and either stainless steel or plastic for the outer shell.
• Versatility: Keeps coffee, tea, soup, or cold beverages at the desired temperature for extended periods.

How It Works

1. Fill with hot or cold beverage.
2. Vacuum gap minimizes heat transfer (no air, no convection).
3. Reflective interior reduces radiant heat exchange.
4. Sealed lid minimizes heat loss during transport and storage.
