I'm crossing my fingers hoping it is. It was hard to find a size chart (gee, I wonder why), but if each XL number climbs with every other number, the rock-throwing mayobarge would be a 8XL: https://www.ashleystewart.com/on/demandware.static/-/Sites-ashleystewart-Library/default/dw3ac6f6ef/images/sizechart/v2-Size_Chart_BTTMS_03.jpg Additionally that would mean it has a 61" waist and 73" hips... Again...please PLEASE be satire
