Body length is taken from the highest point of the shirt to the lowest. The chest length is taken 1" below the armhole.
Awesome hoodie, ordered an XL it definitely fits big (6'2 205lbs) Personally I like a bit of a tighter fit, wanted to exchange it and customer service was the best. No questions asked, and no problems to get a L shipped out to me!
Team Hoodie - Army
Excellent color, shape, and sizing
