Need to hide with rare camo? Then Irish DPM field shirt will help you with that. 

Illegal to own privately in Ireland, I was able to grab a very small bath of Irish DPM, some of them were Irish DPM field shirts. 
 
Only sizes medium available
 
These feature a button closure, two breast pockets, and of course, Irish DPM camo pattern.  
Some may or may not come with patches.
 
Overall these are in good shape, but since these are used surplus, they may have small holes, tears, or stains. But nothing that will prevent you from wearing them.
