Patagonia duck down bivy reversible vest. One side grey one side 2 tone blue. Patagonia logo visible on both sides. Very warm! One side has zip up pockets and the other side buttons. Maybe worn twice. Great condition. No flaws noted. Size tag is no longer on it but I believe it is a size Mens XS. Approx measurements are as follows: 19 inches pit to pit (taken at the bottom of the armpit area) 23 3/4 inches length 18 inches across mid section.
