We hopes to foster new user behaviours and drive the popularity of reusing insulated bottles in place of disposable paper or plastic cups. It can maintain the temperature of a drink for up to 24 hours and is conveniently sized to hold a maximum of 500ml. The rugged form language of a large diameter screw-top makes for easy carrying and fast opening and closing. Its cover is tethered to the bottle with a removable genuine leather strap to help ensure it will not be lost.
