In our ISO 9001:2008 registered lab, we thoroughly test finished products for required stretch, durability, absorption, aging and compression properties. We will not ship a product unless it has met industry and our own strict standards.

Our dedicated QA Inspectors and Lab Technicians document all results for easy reporting, and we label products with a batch number so reports can be easily located and shared. To ensure you get products that are well within their usable shelf life, we closely monitor the status of products in our warehouses and maintain a First In, First Out (FIFO) inventory system.

In addition to performing routine product tests, we are able to apply specific customer testing for their added assurance.
