  • Thermal Air Barrier: Dual-wall construction traps hot coffee or iced brew temperatures while outer glass stays cool and condensation-free.
  • Hand-Blown Borosilicate: High-strength borosilicate 3.3 glass resists thermal shock from -4°F to 300°F (-20°C to 150°C) without cracking.
  • Silicone Pressure Valve: Patented hydrophobic silicone plug at the base safely equalizes atmospheric air pressure between the glass walls.
  • Floating Optical Presentation: Crystal-clear outer wall showcases espresso crema, matcha latte layers, and iced cold brew colors beautifully.
  • Microwave & Freezer Safe: Heat a latte directly in the microwave or chill glasses in the freezer for cold summer refreshments.
