The Active Cashmere® proprietary technology and globally tested treatment process enables the garments to be water repellent, machine washable and durable without compromising the soft hand feel, lightweight nature, and breathability of the cashmere. Water repels off of the garment's surface, maintaining dryness on the inside, and eliminating wetness, staining, odor and water absorption. You can machine wash our garments without the risk of shrinking or pilling, maintaining their original shape and form over countless washes.
