The construction of the XKG Down Transition Jacket exemplifies the performance qualities of the XKG Series and sets a new standard for lightweight and packable layering. Built with 145 grams of 800 fill waterproof down, this jacket has the best warmth to weight ratio of anything in the XKG line-up. This jacket easily fits over any mid-layer piece and can be worn under any of our shell pieces for when conditions are at their toughest. Traditional down has its shortcomings when it gets wet – it loses all its lofting and insulating power and takes forever to dry. That’s why we’ve chosen a new waterproof treated down technology to overcome these faults and deliver a jacket that pushes the expectation of packable down. The exceptional insulating power of this jacket can quickly go from compressed to lofted and traps more air than lesser fills to keep you warmer and performing at a high level. We’ve also added lightweight windproof polyester outer fabric along with a DWR finish to protect you even more when the conditions are extreme. This jacket packs into its left side pocket for easy storage. It has drawstring adjustments in the waist and hood to lock in heat more efficiently. Finished with XKG and King’s logoing on the pull tabs, chest and shoulders. This jacket will thrive during long glassing sessions, testing days in the tree stand, and sleeping or lounging around camp. 800 Fill Traceable Waterproof Goose Down 95% Down / 5% Feather 145 Grams of fill DWR Treated
