The zipper runs the length of the scarf, so it closes on itself into a collared shawl instead of depending on a knot that works loose by the second block. The same track mates with Outlier’s Zipscarf-compatible jackets, turning the scarf into a removable storm collar. The cloth is Albini’s: a dry wool-and-polyester flannel woven in Italy at 250gsm, midweight enough to keep on indoors.
