These NEW 22oz Tumblers feature the same great technology that Swig Life is known for, but with bigger and better features. Each Signature Swig Life Tumbler keeps drinks cold up to 24 hours and hot up to 12 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.
The lid is BPA-free and spill-resistant. 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.
