Kinglet down jacket
Kinglet is a full zip down jacket with 4 inch wide sewn through baffles. This spacing minimizes sewn through cold spots and maximizes loft between lines while maintaining sufficient fill control. Average is around 1 inch of loft and a medium get's around 4oz of 950fp down/4.6oz of 800fp down. Argon 67 outer shell is 0.67oz/square yard and very breathable. Nothing beats down for weight and compressibility for any given warmth. It's drawback has always been that if exposed to moisture it will lose loft. However, now with treated down that can handle moisture much better, the range of use is extended. It has vertical side seam zippered pockets (they can be left off if noted to firstname.lastname@example.org).
Available with a hood or collar.
A size medium is approximately 9-10oz for 800fp, 8-9oz for 850fp, 7-8oz for 950fp.
