Expand your commutes with bold hydration that holds its ground. The Swig To-Go Tumbler 30oz is an expedition-ready powerhouse. Constructed from 304-18/8 stainless steel, this Swig Life® tumbler relies on double-walled, copper-plated vacuum insulation to keep drinks cold for 24 hours and hot for 3 hours. The built-in silicone coaster base secures your drink and prevents scratches on your workspace. A dual-threaded Flip + Sip leakproof lid with a flex carry handle gives you quick access to smooth sips, protecting your valuable craft station from accidental spills. To preserve the quality of your prints, we recommend to hand wash all items.
