This year, sleep-system experts Therm-a-Rest continue to celebrate 50 years of their category-defining outdoor gear with the launch of a special behind-the-scenes video within their European manufacturing facility in County Cork, Ireland. Hosted by Irish Therm-a-Rest ambassador and ultra-marathon runner Conor O'Keefe, the video delivers a never-before-seen glimpse of how the brand's iconic mattresses are built, and the team who build them.
