The Santeco Kola is a 500 ml double-wall vacuum insulated bottle in Moss Green, with a two-tone look: a powder-coated colour shoulder over a brushed stainless steel body. Both the inner and outer shells are food-grade 18/8 stainless steel, and Santeco rates the bottle to keep drinks warm for up to 18 hours and cold for up to 24 hours. It is safe to hold with very hot or very cold drinks and does not sweat or leave water rings. The screw lid is leak-proof and pours easily, and it has a carry loop for a finger or a backpack clip. The wide mouth makes it easy to fill and clean. All parts are BPA free.
