A subsidiary of Optimer Inc., drirelease® uses a patented blend of natural and synthetic fibers. The natural fibers absorb moisture pulling it off the skin and into the fabric. Synthetic fibers repel moisture, forcing it through to the surface of the garment where it evaporates quickly as airflow moves across the fabric. Available in a range of performance blends, drirelease fabric dries 4x faster than 100% cotton and faster than any other performance fabric on the market today.

Optimer Inc. is a chemical research, development and testing laboratory in Wilmington, Delaware founded in 1993 by retired DuPont research scientist, Dr. John W. Moore and his children, John A. Moore, Chris Moore and later, Beth Moore.

Primarily involved with polymers, Optimer conducts research and development by contract for clients worldwide on custom materials, technical solutions and production support for engineering design concepts.

Optimer also conducts polymer research, testing and development for textile-related products on behalf of Optimer Performance Fibers, its consumer products division.

Sterling Capital Partners acquired a majority interest of Optimer, Inc. in February 2008. Optimer is now part of the Sterling Performance Textile Group portfolio, along with DRIFIRE® which Sterling previously acquired in 2004.
