The ultimate personal climate control system. Merino Air-Con was developed to help ensure the wearer remains comfortable through variations in altitude, humidity and temperature. Wrapping merino wool around a nylon/elastane core keeps all the benefits of Merino whilst enabling Mons Royale to create a super-light fabric that is soft, highly breathable and dries quickly. Perfect next to the skin, Merino Air-Con is up to 60% stronger than 100% merino yarn.
