Product Description
Superior Vacuum Insulation: This is the defining feature. The mug is constructed with two walls of stainless steel, separated by a vacuum-sealed space. This vacuum layer acts as a barrier, preventing heat transfer by convection and conduction, meaning:
- Excellent Temperature Retention: Keeps hot beverages (coffee, tea, hot chocolate) hot for several hours (typically 3-6+ hours) and cold beverages (iced coffee, water, juice) cold for much longer (typically 6-12+ hours).
- Sweat-Proof & Condensation-Free: The exterior remains dry and comfortable to touch, even when holding icy cold drinks, preventing rings on furniture or moisture in your bag.
- Cool-to-Touch Exterior: Even with boiling hot liquid inside, the outer surface remains safe and comfortable to hold.
