Material

This product is made with Polartec® Alpha® Direct (136g/m²).

Developed in response to US Special Forces' need for an insulation system that could adapt to extreme temperature fluctuations and cycles of movement and rest, Polartec Alpha® was designed to provide consistent warmth during active wear while offering excellent breathability. Polartec Alpha®

Direct is an evolution of Polartec Alpha® insulation technology. This technology is designed to allow direct contact with skin and other fabrics, eliminating the need for a lining. This improves the fabric's breathability and performance, and refines the shape and size of the insulating fibers. Alpha® Direct's unique construction improves the product's breathability and reduces its weight.
