Ummm...if you're selling the item, you should probably just measure it.
But Unionmade sold it and they had measurements on the site. Might have to google search for a cached version if they are sold out.
Finally copped my first SNS!!! I got a Navy-mix Ion just like my nephew NAMOR. Chose it over the black pullover memento, which if anyone wants, is about $170 shipped right now in L and XL.
I read that LA Guy said the Ion is the thickest/most dense of the SNS cardigans. Is this true?
It's thicker than the Stark (which is listed as 5 gauge - the Ion is 6 gauge, iirc), but there are some heavier gauge cardigans.
