I recently bought an Aero Type III thru Thurston Bros. (I should really do a write up on it.) I ordered it in the Vicenza Blackened brown. Definitely a boxy fit. After the fit jacket, and measurements, when I took delivery, it was still too loose and too long. IMHO a Type III should fit tight and short. I ended up shrinking it down with the HWT. Here's a pic. BTW- according to Thurston Bros. the Vicenza is just as thick and the same weight as the regular FQHH.
I had samples and the Vicenza was thinner than FQHH and definitely thinner than steer.
I kind of assumed these Type III's had a boxy fit buy doing some internet image searches. I may now have to re-evaluate my want for the Type III.
