Fox's tumbler is set apart by the use of top-grade 316 stainless steel inside, providing superior anti-corrosion properties and resistance to acids. 316 stainless steel is the recommended option for liquids such as wine, cola or breast milk, but it works for anything! The outerior is 304 stainless steel, with a grippy matte surface.
6 layers of insulation keep your drink either hot or cold for up to ten hours. The lid conveniently functions as a cup.
Initially available in Pearl White. 15 oz (445 ml).
