Outlast Introduces Heat-Management Polyester Fiber

Boulder, Colo.-based Outlast Technologies Inc., developer of Outlast®
temperature-regulating technology and phase-change materials (PCMs) and applications, has developed
the first heat-management polyester fiber — a bicomponent fiber with a PCM core and polyester
sheath that combines climate regulation with conventional polyester fiber characteristics, such as
low moisture absorption; the ability to transport moisture; improved wrinkle, water and wind
resistance; and high tearing and abrasion resistance. The Outlast polyester fiber is suitable for
next-to-skin applications including T-shirts, socks, baselayers, athletic wear and

Outlast will launch staple polyester fibers at the Outdoor Retailer Winter
Market in Salt Lake City in January, and later will introduce filament fibers. The debut of Outlast
polyester follows the company’s introduction of Outlast viscose fiber four years ago and Outlast
acrylic fiber with PCM 11 years ago.

“Outlast is a leading R&D company in the PCM industry and the launch of
Outlast polyester fiber demonstrates our commitment to innovation,” said Greg Roda, president and
CEO, Outlast Technologies. “Outlast viscose and Outlast acrylic have seen great success and this
new polyester fiber allows Outlast technology to infiltrate the functional apparel market, leading
to company growth on a global level.”
