These NEW 18oz Mugs feature the same great technology that Swig Life is known for, but with bigger and better features. Each Signature Swig Life Mug keeps drinks cold up to 9 hours and hot up to 3 with its double-wall, vacuum-sealed copper coated insulation. The non-slip silicone base keeps your cups from tipping or making too much noise when you set them down. Plus...it fits perfectly in most car cup holders!
The newly-designed SEAL-TITE Tritan lid is BPA free, spill resistant and shatterproof. These clear lids seal tightly with a rubber seal gasket while allowing you to see inside. The straw friendly opening can be covered with the sliding closure to minimize spilling. Always use caution when handling hot liquids and please take care not to drink hot liquids from any straw.
