The manufacture of the original authentic, so called, red Airam thermoses began in 1934. A boiling liquid stays at a temperature over 50 degrees celsius for at least 24 hours - a promise that still holds today. Airam steel thermoses have established and solidified their status and position in outing and camping uses as well as at the coffee tables of homes and workplaces. The broad collection is comprised of a wide selection of bottles, jugs, dispensing (pump) thermoses and mugs. All Airam steel thermoses have a 5-year guarantee.
