Peruvian Perfection 100% Alpaca Wool Gray, Brown, Ivory Block Pattern Armpit to armpit = about 24 inches Length = about 31 inches Sleeve = about 38 inches Size (Label says XXL) But you will have to go by the measurements. From what I can tell, the width is what you would normally consider Medium to Large, the Length is what is typically more a Medium and the Sleeve Length is For a Tall Man. For reference, my husband who is 6'4" and size XLT liked the sleeve length but found it too small around. Worn Once for a couple hours.
