Part of the prestigious Swiss Peak Elite series, this massive 1000ml flask is built with double-walled 18/8 grade stainless steel. The interior wall is plated with copper for ultimate thermal conductivity, allowing it to keep drinks hot for 8 hours or ice-cold for an incredible 24 hours. The durable black powder-coated finish is resistant to fading and cracking, and the entire unit is leak-proof and designed for heavy-duty travel or outdoor use.
