I have a US Authentic A2 horsehide..very thick and heavy..and a horsehide US Wings...not nearly as heavy but also IMO a very servicible jacket. The US Authentic ...slim cut ...US Wings a much more generous cut ...I also have a goatskin orange label Cooper A2 goat which is a very thin skin and slim cut. Realizing that the wartime A2s were made by many companies with different hides ..is there any consensus from FL on how heavy / thick in comparison ... those jackets were...??
