Both JC Penney and Lands End sell husky size clothes for boys. Usually husky sized pants for boys are about 3 inches bigger on the waist than the regular boy’s size. For example, a boy’s size 10 regular has a waist size 24 inches to 25 inches and a seat of 27 inches to 28 inches. A boy’s husky sized pants in a size 10 includes a waist size of 27 inches and a seat size of 30 inches to 31 inches.
