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 Gortex rain pants. These would be worn over your regular combat trousers to help protect you from the rain.
 
Sizing: Since these are meant to be worn over your combat pants, they run quite large. Fully loosened, the size small measures about 38 inches for the waist, and the size medium measures about 40 inches for the waist.
Please consider this when purchasing one.  
 
Only 2 available, and the size small is missing the suspenders, hence the price difference. 
 
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.
