For over 100 years Thermos has been the leading manufacturer of convenient, insulated products. The Raya line of lunch and can coolers is a perfect combination of fashion meets function. Beneath the bold, trendy prints, unique shapes and premium fabrics is IsoTec insulation, which features a layer of closed-cell polyethylene foam positioned between an outer layer of textile and an additional moisture repellant, heat-sealed PEVA lining. Raya coolers and totes are perfect for packing a lunch for the office, or sodas for the beach. Interior and exterior can be wiped clean with a sponge and mild soap. Not for use in the microwave or dishwasher.
