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 powder-coated finish keeps your Swig looking fresh and is dishwasher safe! LIDS + STRAWS: This Swig includes a slide-closure lid to reduce messes while on the move and to maximize temperature retention. The straw-friendly opening can be covered with the slider to minimize spills when not in use. The slider is removable for easy cleaning and will snap back in place.
