The Santeco Kariba is a 500 ml double-wall vacuum insulated thermal tumbler, here in Carbon Black. It is made for coffee, tea or cold drinks on the move: the body is 18/8 food-grade stainless steel with a powder-coated, sweat-free finish, so it stays comfortable to hold with hot drinks and does not leave water rings with cold ones. The clear lid has a flip clip that opens and locks with one hand, and double silicone gaskets on the lid and the clip make it leak and spill resistant, which helps in a bag or a car. Santeco rates it to keep drinks hot for up to 6 hours and cold for up to 12 hours. At about 20.5 cm tall it is a good size for a commute or a long day at the office. All parts that touch your drink are BPA free, and the reusable tumbler cuts down on disposable cups. Santeco is a French-designed drinkware brand.
