Polartec Introduces Polartec® Alpha® Insulation
Polartec LLC, Lawrence, Mass., has introduced a man-made fiber insulation that provides improved
breathability and moisture-vapor transport in puffy-style apparel.
The company reports Polartec® Alpha® is highly stable and enables the use of more open and breathable fabrics on the outer and inner layers of puffy-style apparel, in contrast to down and existing man-made insulation batting used under high-density woven layers that form a vapor barrier but can trap moisture inside a garment. Polartec Alpha continues to insulate when wet; dries faster than traditional puffy-style insulation fabrics; is inherently wind-resistant; provides warmth; and is lightweight, durable and highly compressible.
Developed for the U.S. Special Operations Forces (SOF), the insulation received the highest ratings of any product tested by SOF. Polartec Alpha jackets will be supplied to all Special Forces operators, and the insulation will be offered at retail next fall.
