The construction of the XKG Down Transition Jacket & Pant 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 in the jacket and 135 grams of 650 fill waterproof down in the pant. These pieces have the best warmth to weight ratio of anything in the XKG line-up. This jacket and pant easily fit 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 & pant that pushes the expectation of packable down. The exceptional insulating power of this jacket and pant 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 the most durable lightweight windproof nylon outer fabric along with a DWR finish to protect you ever more when the conditions are extreme. The jacket is available in Charcoal/Dark Olive & Olive with sizing small to 3XL and the pant is available in Charcoal with sizing S-2XL.
