Champion Athletic Apparel has unveiled its final prototype of its Champion
Supersuit that will be the thinnest extreme-weather apparel gear ever
designed and tested at high altitude on Mount Everest.
The Champion Supersuit insulation is just 3 millimeters thick,
compared with a typical goose-down jacket thickness of 40 millimeters,
and uses a nanotechnology insulation layer and a proprietary radiant
warmth system. The result is a breakthrough ultrathin cold-weather
garment that is no thicker than a typical computer mouse pad but
provides equal insulating properties, greater mobility, and superior
wind resistance than typical extreme weather gear.
"The Champion Supersuit uses advanced technology to conserve,
capture and return heat unlike any other extreme-weather apparel
currently being used on Everest,” said Mike Abbott, director of research
and development for Hanesbrands Inc., the parent company of Champion apparel.
"It has been a rewarding research and development project. By developing
the Supersuit and other garment layers to be used on Everest, we have
identified new Champion products to roll out and new features and
enhancements to potentially add to our everyday line of Champion
Athletic Apparel.”
Champion is outfitting a Mount Everest climbing team led by
mountaineer Jamie Clarke with cutting-edge socks, base layer, insulating
layers, soft shell jackets and pants, hard shell jackets and pants, and
the Champion Supersuit. Clarke has been testing the gear and will
wear a one-piece full-body Supersuit on Everest in April and May to keep
him warm and mobile in the high winds and severe cold on the highest
reaches of the 29,035-foot mountain.
"We were given the challenge to develop a summit suit that would advance
the state of cold-weather gear, that wouldn’t look like anything else on
the market, and that would protect climbers against extreme temperatures
and conditions on Mount Everest,” Abbott said. "We have worked with
several technology partners in and out of the apparel industry,
including Element 21 Golf Company, which supplies the nanotechnology
insulating material for the Champion Supersuit. We have made some
significant breakthroughs, including the ability to use the nano
insulation in commercially viable apparel products for the first time.”
Hanesbrands has a booth at the Outdoor Retailer Show in Salt Lake City
for its Champion athleticwear and Duofold base layer
brands. Champion is displaying prototypes of its Supersuit jacket
in the booth, and Abbott and Clarke will be in the booth from noon to 4
p.m. Friday to discuss the Champion Supersuit project and the
Everest expedition.
The Making of the Champion
Supersuit
The Champion Supersuit is made up of four layers, each with
unique characteristics to preserve warmth. The Supersuit is designed to
prevent the loss of heat via air movement (convection), promote the
insulating effect of still air (prevent conduction), and capture heat
produced by the body (radiant heat source). Details of the layers
include:
Supersuit Outer Layer (anti-convection). A hard-shell polyester
fabric mated to a wind-barrier membrane prevents sub-zero winds from
penetrating the inner layers and conveying heat away from the body.
Blocking strong winds in extreme cold conditions prevents compromising
the effectiveness of the insulating and radiating layers of the
Supersuit.
Supersuit Nanotechnology Insulation Layer (anti-conduction). The Champion
Supersuit is the first commercially viable application of Element 21’s
Zeroloft Aspen Aerogels, which allow the Supersuit to be so thin.
Zeroloft insulation has four times the thermal insulation of goose down
because the transparent solid gel is made up of nano-sized multisided
spheres that have so much surface area that air movement is restricted,
which reduces conduction and prevents heat loss.
Radiant Foil (radiant warmth). A metallicized foil membrane
reflects heat generated by the body and returns it back to the person
wearing the Supersuit through conduction. This body heat is typically
lost when apparel relies on insulation alone.
Inner Lining (wicking). Made of polyester technical fabric, the
inner lining draws moisture away from the body.
Using the Zeroloft Aspen Aerogels insulation in the Champion
Supersuit is a breakthrough for the apparel industry. Aerogel is made of
puffed glass and is the lightest solid on earth. It has historically
been used by the natural gas and oil industries to insulate deep-water
pipelines.
"Our expertise and relationships in the textile science industry allowed
us to find a material that no one else was using,” Abbott said. "We
search for proven concepts and materials and determine how to reapply
them in the apparel industry. We felt that aerogel had a lot of
potential to give our climbing team more mobility while protecting them
from the elements.”
An additional side benefit of the development of gear for the Everest
expedition is that Hanesbrands also plans to use aerogel to insulate
equipment in its manufacturing facilities as a way to reduce energy
consumption.
From Everest to Everyday Activewear and
Athleticwear
The Champion and Duofold brands will use the Everest
project’s research discoveries for new products and enhanced products
for years to come. The first products inspired by or influenced by the
Everest project will come to market in fall 2010.
Champion will introduce Cold Weather Gear that can be layered in
various combinations to promote warmth and comfort, a technique that
will be used during the Mount Everest expedition. The Champion
Cold Weather gear is value-priced training activewear made from
lightweight fabrics to maximize mobility and reduce bulk, even while
layering for warmth in modest temperatures.
The compression base layer, quarter-zip and full-zip tops and soft-shell
jackets will feature soft fabrics, ergonomic design for stretch and
movement, chafe-resistant seams, lock-down zippers and grip-tape at leg
openings for safety, and MP3 and invisible zippers for convenience. The
gear is designed for colder-weather training, running, mountain biking,
hiking and other outdoor activities.
Duofold will introduce an advanced seamless base layer product in
the fall that is identical to that developed for Clarke and the other
climbers on Mount Everest. Using seamless construction, both the
synthetic top and bottom base layer pieces have at least six knit
techniques to create zones that deliver specialized characteristics to
promote moisture wicking, mobility and comfort. For example, the fabric
has a raised surface in the back to promote wicking moisture, while
compression in the shoulders help keep muscles loose and limber.
One piece that the Hanesbrands R&D team did not have to invent for the
Mount Everest expedition was the already available Duofold Varitherm
Mid-Weight Dri-release Wool top and bottom insulating layer. The
expedition team will wear a heavier weight of the same product.
