Until recently, the only A2 reproductions worth considering were those made by Eastman Leather Clothing down in Devon, UK.

However, there is a new ‘kid’ on the block in Seattle, USA based Goodwear Leather Clothing who’s attention to detail cetainley seems to match or exceed Eastman’s.

There’s also Aero Leather Clothing in Scotland, and Real McCoys’s based in New Zealand.
Anything from anywhere else isn’t worth considering if an accurate A-2 is something your looking for.
It’s worth having a read through this first….
