Kinglet down vest
Kinglet full zip vest is a full zip down vest with 1.5in of loft and an Argon 90 outer shell. 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.
Approximate calculated weights 5.6oz - 800fp, 5.4oz - 850fp, and 5.2oz - 950fp.
