Gentlemen: Is all the Vicenza leather used by Aero veg-tanned? Is it a Horween product or from an Italian factory? Or is it sourced from multiple companies?.. My question arose because I’m looking through the Aero sales section, and in a few of the listings for Vicenza jackets, the leather is described as veg-tanned. However, on most Vicenza jacket listings, the tanning process is not mentioned at all. I apologize, I know there’s been a lot written about this, I couldn’t find anything current however.
