This Fusion Thermo Flask is made of double insulated material. Double wall vacuum insulation makes drinks stay cold, iced or hot for several hours.

The Flask is made of safe stainless-steel material (outer and inner 304 and bottom 316 stainless steel) for safe use. Stainless steel and silicone straw included.

The cup is leak-proof in all directions, wear-resistant and scratch-resistant. We’ve also included an ergonomic, comfort-grip handle, so you can easily carry your ice-cold water to work, meetings, the gym or trips out of town.
