Sea to Summit Delta Insulated Mug

This mug features a groundbreaking advancement in thermal insulation. Sea to Summit uses 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
• Leak proof sipping lid. Patent-pending Protex hex pattern base
• Volume: 16 oz (473 ml). Weight: 4.4 oz / 125g
