Eco-Engineering™ Renewable Wool

Keep it green.


Simply put, renewable resources are resources replaced by nature faster than we can use them. From food, to energy, to everyday items, renewable resources are rapidly becoming crucial to the sustainability of our way of life. One such resource that offers unique performance benefits is wool.

  • Wool/recycled polyester blend
  • Promotes warmth, wicking and quick drying
  • Naturally odor resistant

Polartec® Pure Wool™


Merino sheep produce a particularly fine quality wool that is soft and comfortable next to skin, while offering the seemingly disparate performance benefits of being warm in the cold, but remaining comfortable during heated pursuits.



Wool Structure


Wool has a very complex structure making it one of nature’s greatest defenders from cold, heat, and wetness. Microscopic scales cover the surface of a wool fiber, similar to roof shingles. The scales are hydrophobic, and their stacking gives the fiber water repellency. Yet, moisture vapor can penetrate under the scales where the cortex, or inner structure, is hydrophilic. This gives the fiber breathability. Wool can be processed to give a garment water repellency or water absorbency (wicking), depending on how much of the scales are left on or removed. In addition, the chemical make-up of the cortex causes wool to release and absorb heat as moisture is attracted to and released by the fiber.

On a more macro level, wool is a crimped fiber, meaning it has little curls. This creates pockets between the fibers for air entrapment, which promotes insulation against both hot and cold temperatures.
