TRREX TECHNOLOGY KEEPS YOU COOLER!
PERFORMANCE - COMFORT - CONVENIENCE
TRREX is a revolutionary cooling apparel system which helps maintain a more comfortable body temperature in extreme conditions.
Almost 90% of the body’s heat is located in the torso. When you work, play, or compete, excess body heat is generated and the body has to release that heat to maintain a healthy core temperature. In high heat or humidity, it has to use extra energy to protect against the heat. The body uses two properties of thermodynamics to naturally beat the heat – evaporation and convection.
TRREX uses that same science. It consist of two unique and interdependent elements: the TRREX athletic shirt fabric and the TRREX Coldpak.
TRREX ATHLETIC SHIRT
The patent pending fabric uses evaporation to pull moisture and heat away from the body. Its special vapor cells also efficiently disperse hot and cold across the shirt. The material is soft, the fit is comfortable, and the design represents current style.
Evaporative Properties Convective Properties

TRREX COLDPAK
The patent pending cooling inserts are different than anything on the market today. This ColdPak is superior in its combination of functional benefits attained through a unique set of materials and product design.
Thin and lightweight, for storage and shipping.
Lasts for 2-5 hours, depending on temperature and humidity
Can get down to subzero temperatures
Reusable
Flexible enough to adjust its shape to fit a desired surface
Nontoxic, prevent bacteria and mold, will not emit slimy ooze like
most gels.
Working in combination, the Coldpak serves as the cold source and the fabric distributes that cold temperature across the shirt. TRREX’s revolutionary performance apparel keeps you both dry AND cool, for maximum comfort and even enhanced performance, and is designed to
last for several hours.
TRREX’s design has been “combat tested” through lab thermal imaging,
US Military, and by NASCAR pit crews. Results demonstrate enhanced physiological comfort and design approval. Outside studies confirm that cooling the body actually increases physical performance.
The inserts can also stand alone for first aid and pain relief.
