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 "Old Gen" parkas. They feature two large breast pockets, two large waist pockets, one internal breast pocket, adjustable cuffs, a hood, two sleeve pockets, and an adjustable waist. 
May or may not come with patches. 
 
These run big. I normally wear a size Medium and the size Small fits me perfectly. 
 
Overall, these items are in good condition, but since they are used surplus, they may have minor imperfections such as small holes, tears, stains, and/or markings.
 
One parka is a Grade 2 due to it missing the zipper. Other than that, the parka is in great shape, and the zipper could be replaced.
