Finally finished this vest. I started this vest February 3, but had to undo at least 6 inches of knitting after I discovered it was way too big.
Zipped Vest by Veronique Avery, in Knitting Classic Style
size medium (but for an XL man
5 skeins of Cascade 220 in a charcoal gray, 24" separating zipper
The pattern is moss stitch (but a different variation than the one I have used before) alternating with welts. I loved that it is knitted in one piece, no seaming, just turning under the facing on the neck.
