From the pattern:

Size 24” (27”, 30”, 33”, 35”, 40”): 8 oz. (10, 11, 13, 16, 18)

From the designers:
If using double-stranded worsted rather than bulky yarn, you would need 550 yards of worsted weight yarn for the smallest size and 1200 yards of worsted weight yarn for the largest size.

A “fix” to even up the knit and purl rows for the top of the vest is included in the Instructions on page 2.
