If you're in the market for an insulated bottle or tumbler, you'll find a lot to choose from. There are mugs and bottles targeted to sport-enthusiasts, outdoorsy types, and extreme adventurists… premium drinkware with women in mind. The company’s cups, tumblers and bottles rely on the same insulation technology that keeps other stainless steel hydration vessels cold or hot - including vacuum insulation, stainless steel double-walls and copper-coated linings. But SWIG differs from its competitors with its creative and appealing designs. SWIG offers more shapes, sizes and color choices (20!) than anyone else on the market, but what really sets them apart is their insulated stainless steel stemless wine cup – a SWIG original creation that took the marketplace by surprise!
