The Perka® Blake 8 oz. vacuum bottle features a double wall stainless steel construction, a minimalist design, and a stainless steel cap with a silicone seal. It's conveniently portable as it fits comfortably in the hand and in most car cup holders. It will keep your tea hot for 12 hours and your iced coffee cold for 24 hours. This bottle 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.
