Sea to Summit Delta Insul-Mug

This mug features a groundbreaking advancement in thermal insulation. We use an integrated molded EVA sleeve that actually insulates the liquid inside the mug, unlike double-walled mugs which only protect your hands but donÂ’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, non-absorbing EVA insulating outer sleeve
• Patent-pending Protex™hex pattern base
• Leak proof sipping lid
• Assorted colors: Blue, Orange, Green, Grey
