The Perka Cooley Vacuum Insulated Tumbler is designed to keep your cold water cold for 24 hours and hot tea hot for 12 hours. Its vacuum insulated construction provides temperature retention, and the durable powder coat finish prevents sweating and scratches. The translucent push-in lid features a silicone seal to secure the sipper when you enjoy your hot drink and the food-grade stainless steel straw for cold drinks includes a silicone tip for a more comfortable drinking experience. The Cooley is perfect for daily use as it fits into most standard car cup holders, is FDA compliant, and BPA Free. A portion of all proceeds is donated to Shelter to Soldier, a non-profit organization that rescues dogs to train as service animals for veterans in need.
