Features & Benefits

Highly Breathable and Thermally Regulating
Polartec Alpha Active is a non-migrating lofted fleece insulation that offers superior breathability and moisture management. This versatile insulation allows us to construct a garment with a more open liner fabric, greatly improving breathability. By keeping moisture vapor moving freely through the fabric, it increases overall air exchange and speeds up dry times. This advancement increases thermal adaptability in changing conditions and different phases of physical activity.
Durable Water Repellent Finish
The DWR finish resists light precipitation and prevents the face fabric from wetting out.
Brushed Fleece Hand Zip Pockets and Interior Zip Chest Pocket
The zippered chest pocket secures your necessities and doubles as a stuff sack. Hand warmer pockets are lined with brushed fleece for added warmth.
Neck and Chin w/ Brushed Tricot Lining
The neck and chin are lined with a brushed tricot to prevent chafing and add warmth and comfort.
