Your body cools itself by first releasing heat to the air around it
and then by producing perspiration which evaporates, also producing a
Conventional clothing creates a "dead air" space around the
body...insulating it from the air that could provide cooling. Your
body begins to sweat in an effort to become cooler.
Many conventional clothing fibers such as cotton will absorb this
sweat and swell up, closing the pores in the garment and trapping even
more heat. Cotton under racing leathers is the worst possible
So called "technical fabrics" use synthetics that will not swell and
also repel water vapor to encourage evaporation. Too much evaporation
leads to rapid dehydration...a potentially deadly problem for
motorcycle riders and motorsport drivers.
COOL STUFF products go the next step and combine these "technical
fibers" with an acrylic fiber that contains thousands of chemically
charged bubbles that react to skin temperature and can help defer
COOL STUFF foam uses a “phase change material” technology to absorb
and release thermal energy. The phase change “bubbles” applied to the
foam are activated by the temperature of your body.
The pads are placed between your skin and your helmet or backpad liner
so that the pads can make contact with your body. When your skin
temperature is above 95 degrees fahrenheit, the COOLSTUFF pad starts
to provide a cooling effect. When your skin temperature is below 95
degrees, it provides a warming effect.
Once the phase change material is completely "saturated", then the pad
will act as an extra insulator between you and the
environment...continuing to provide extra comfort and impact
protection just like the other foams in your helmet or backpad.
COOL PANTS and COOL SHIRTS are
worn under your leathers or riding apparel, directly against the skin.
Available in men's or women's designs, in black or white.

• Blended fabric consisting of 45% Outlast
Adaptive Acrylic fiber and 55% polyester. Garments are set to activate
at an average skin temperature of 90 degrees F. These garments can
reduce skin temperature up to 2 degrees compared to conventional
polyester based garments. • Treated with a wicking agent to repel moisture and allow fast
drying. • Cuffs and ankles are elastic for an easier fit under riding or
racing apparel. • Waist bands are elastic. Women's waist band includes a scalloped

COOL HEAD helmet pads are inserted
directly into the top of your helmet. Absorbs heat from inside the
helmet allowing better concentration and comfort.
COOL HELMET Pads from Cool Stuff feature:
• 10mm thick foam pad saturated with Outlast Technologies Adaptive
Temperature Regulation technology. Set to activate at 90 degrees F.
over the point in the body where the greatest heat release occurs.
• Pads are sandwiched in a nylon mesh packet that is inserted directly
into the top of the helmet.
Cool Stuff products
are made of a patented technology developed by NASA for the Apollo
space program. Motocoolstuff, Inc. is bringing this technology into
the motorcycle industry by marketing a line of garments that contain
the unique Outlast Technologies phase change fibers.
The patented Outlast Temperature Regulation system used
in the MotoCoolStuff pads contains micron-sized Thermasorb additives.
With their unique ability to absorb and release heat, Outlast cools
you when you're warm, and warms you when you're cool. When you stop
riding, the Outlast Temperature Regulation system "recharges" itself
automatically for continued comfort and protection.
MotoCoolStuff shirts and pants use the same technology as our pads but
embedded directly into the fibers of these unique garments. Outlast
fibers in the MotoCoolStuff garments under your leathers provide the
best temperature regulation available. Now you can slip out of your
leathers without the sticking and grabbing of the past...and you can
be more comfortable even at higher outside temperatures.
These specialized garments were pre Under Amour and work very well as
under garments for your race suit. I have keep all that I need for my
personal use so here is what is left.
Unfortunately the Cool Stuff company has not survived.
