A necessity for any true backcountry outing, the Kelvin Active Jacket features 80 gram Polartec® Alpha insulation for maximum versatility - an ideal outer layer in mild conditions and perfect insulation under a shell when the mercury plummets. Soft, quiet and breathable, this workhorse knows no off season.

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.

Sitka sizing is comparable to New Zealand and Australian sizes - so if you wear a large in a work shirt a large in Sitka will generally be the right fit too. 

Order the same size in base and outer layers, the outer layer in the same size is designed to fit over the layers that are likely to be worn underneath it.
