Alpha®

The U.S. Special Forces needed a technology that didn't exist yet.


Polartec® Alpha® was originally developed for the U.S. Special Forces when they required a more advanced insulating material in their combat uniforms. This fabric is a new technology with active insulation that regulates core body temperatures during both dynamic and static activities. This latest advancement in adaptable breathability helps eliminate the need of shedding or adding layers while on the move.

Benefits
  • Superior breathability
  • Warmth without weight
  • Packable
  • Fast drying
  • Easy care
  • Available in multiple styles and weights
Best Uses
  • Adaptable temperature regulating insulation

Technology

Adjusting or completely shedding layers to release excess heat and moisture vapor is not always a viable option during activities. Pit-zips and vents have traditionally helped to balance airflow and warmth in micro-climates, but they leave surface areas exposed to the elements in the process. Polartec® Alpha® is the first high performance fabric to materialize the concept of active insulation.

By placing patented low density fibers between air permeable woven layers we created a more efficient fabric for regulating warmth and transferring moisture. This advancement increases thermal adaptability in changing conditions and different phases of physical activity.

HOW IT WORKS

Polartec® Alpha® is a highly compressible fabric, easily layering with other materials and storable in small spaces. A stable core of lofted knit fibers prevents fiber migration to keep a uniform consistency, even after heavy wear and repeated laundering.

By keeping moisture vapor moving freely through the fabric it increases overall air exchange and drastically speeds up dry times. This reduces discomfort from saturation and prevents it from turning into a sponge. Additional durable water repellency in the outer woven layers give Polartec® Alpha® the trusted ability to perform in the most challenging of environments.
