Long considered a trusted partner by parents in providing healthy food and drink options for kids, Thermos brand has brought its superior insulation technology to FOOGO, a line of children's products for ages six months and older. Freshness and safety go hand in hand. If not kept at the right temperature, food and beverages can spoil, causing potentially dangerous bacteria to form. FOOGO stainless steel products feature THERMOS double wall vacuum insulation which has been shown to inhibit the growth of bacteria in a laboratory test performed by Cornell University, and will keep contents cold and fresh for six hours. In addition to providing added protection from spoilage and food borne illnesses, Thermos brand offers parents extra peace of mind in knowing that FOOGO products use BPA-free materials. To clean, hand washing is recommended for best results, or top rack dishwasher safe.
