Here is a sizing chart that i got from Tyson Hall
Armada 0910 Sizing Chart
And as far as my sizing opinion: I have last years Inverse in an XL, and it fits as big as my XXL Oakley PRS or my XXL Helly Hanson. and im 6'2" 220lbs
And Tyson also told me the Lorenzo is suppose to be the new replacement for the Hex tech, he says it has "5,000/3,000 waterproof/breath-ability" which is pretty sweet for a soft shell, but if i was going to pay over $100 on a soft-shell, i would just pony up and get a Arc'Teryx Gamma MX, which is like $40 more, for better ratings.
