RPM, Inc., a Minnesota-based manufacturer, has been in business for over 40 years. They started out in the promotional products industry working with companies to provide unique giveaways for their customers.

During this early phase of the business, Drymate came across a unique item – a blanket with a waterproof backing. Because there was nothing like it on the market at the time, they saw the potential for building a product line based on the material. So they bought the company that manufactured the material and, through continuous innovation, have created a multi-category line of waterproof mats that we sell under the signature brand Drymate®.
