PrimaLoft, Inc., the world leader in comfort solutions, high-performance insulations and fabrics, has collaborated with MitsuiBussanTechnoproductsCo., LTD, acompany specializing in the research and development of innovative textile technology, to manufacture PrimaLoft® Performance Fabric.


Launched at the Outdoor Retailer Winter Market in Salt Lake City, UT, the PrimaLoft® Performance Fabric collection consists of a broad range of technical knits primarily developed for base layer applications.

“Performance and comfort are the hallmarks of PrimaLoft® insulating products, and it made sense to extend our technology into a line of performance fabrics,” said Joe Rumiesz, Vice President, PrimaLoft. “Mitsui, who is known for its tremendous expertise in the design and manufacture of fabrics, has been a long-term partner with PrimaLoft in Japan and we are grateful for its collaboration on PrimaLoft® Performance Fabric.”

Created with the PrimaLoft® ‘Feel the Performance™’ concept in mind, the fabric collection is categorized into Gold and Silver groupings to distinguish each fabric’s specific performance and potential end-use.

The high-performance Gold group includes knits positioned as PrimaLoft® Performance Fabric Heat or PrimaLoft® Performance Fabric Dry. The Heat collection delivers maximum comfort and temperature-regulating properties, and the Dry collection offers exceptional moisture management and rapid drying characteristics.

The Silver group features Merino wool/poly blends along with other knits constructed of technical fibers and advanced materials to provide moisture management, softness and comfort within a broad range of activities and weather conditions.

“Initial feedback on the fabrics has been great,” said Joy Gruver, Business Development, Mitsui Bussan Techno Products Co., LTD, representing PrimaLoft® Performance Fabric.. Brand designers we’ve met with who use PrimaLoft® brand products in their product lines view the new fabrics as a natural fit and reinforcement to the PrimaLoft® story, which is all about comfort and performance,” added Gruver.
