Delta Insul Mug

Sold Out

5.0 star rating 0 Reviews

Past season
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
• Please note that Delta products should not be used in a microwave (early production versions incorrectly had a microwave-safe symbol)

All sales are final.
