The Shackleton Fuchs Down Jacket is an ultra-insulated outerwear garment designed with style and comfort in mind to work well as we head into the coldest months of the year. The garment is constructed with 215-grams of 800 fill power RDS-certified goose down that is kept in place with a box wall baffle design to virtually eliminate cold spots as it locks in heat. The garment, however, is meant to not feel too bulky to accommodate everyday wear.

The Shackleton Fuchs Down Jacket has been tested down to -20-degrees Fahrenheit in the Rockies and the Alps to ensure it can withstand even the harshest winter conditions. The garment is finished with the Pertex Shield outer to maximize weather resistance.
