Why Polartec® Alpha?

With a focus on thermoregulation, this down alternative enhances comfort and warmth during intense adventures in unpredicatable forecasts. It’s extremely durable, and—unlike conventional synthetic insulations—works with breathable lining fabrics.

How Does It Work?

Using lofted fibers connected to a solid mesh core, body heat and moisture vapor are released before the garment gets saturated. This keeps you comfortable and dry, plus improves airflow and creates an even distribution of warmth.
