This is a coverall made of shiny Rubber NG fabric which is 1000g/m2 thick! It is the same material they use for their Strong chest and thigh waders. It feels and functions exactly like Opalo.
 
Shiny!
Very thick!
Cleans easily!
Looks hot!
 
There are also wind locks / cuffs on both the legs and arms.
 
The size XS/48 I have in stock has neoprene cuffs.
