Since the Defense Act of 1954 was implemented, it has been illegal for civilians to own or wear Irish uniforms without proper authorization. And since the Irish government does not surplus their uniforms, it is almost impossible to get a hold of authentic Irish DPM. 
 
But The Surplus Front has managed to land a large batch of Irish DPM.
 
First developed in 1999, Irish DPM (Disruptive Pattern Material) has been used by its armed forces ever since. 
 
Available are Irish DPM field shirts. Choose between the Old Gen or New Gen patterns. 
The difference?
Old Gen will have two breast pockets
New Gen will have two sleeve pockets instead of breast pockets. 
 
The shirts close via button, and may or may not have the Irish flag and/or name tapes.
 
Overall, these are in good shape, but since these are used surplus, they may have small holes, tears, stains, and/or markings.
