Delta Insul-Mug

Go Back

This mug features a groundbreaking advancement in thermal insulation. We use an integrated molded Polyurethane sleeve that actually insulates the liquid inside the mug, unlike double-walled mugs which only protect your hands but don't necessarily keep your beverages hot or cold. Well designed leak-proof sipping lid has an ergonomic rolled edge and thumb grip with hang loop.



Excess liquid flows back into the sipping hole because of the concave design of the lid.

  • Ultra-durable food grade Nylon 66 inner is BPA free
  • Fitted, ThermoSkin non-absorbing insulation sleeve
  • Patent-pending Protex™ hex pattern base
  • Leak proof sipping lid
  • Assorted colors: Blue, Orange, Green, Grey
Proper Use:
  • Please note that Delta products should not be used in a microwave
  • (early production versions incorrectly had a microwave-safe symbol)
