Anti-perspiration pad, also known as anti-sweat pad. It works quite simply by creating an air gap between you and the mattress, reducing or preventing sweating. Although the principal is simple the technology is far from simple. 3mesh from Muller textiles in Germany is made from thousands of tiny fibres that literally create an air gap allowing air to circulate. We at High & Dry Manufacturing Ltd then convert the 3mesh spacer fabric into a mattress protector with an elasticated skirt to hook over your mattress and a quilted face with poly cotton lining. It really works.
