Here we have the best thigh waders on Earth!  Made with high quality, shiny and easy to clean Opalo-fabric. 
 
These sizes I have in stock for immediate shipment.
 
Here are some information from the manufacturer:
 
The thigh waders have been produced with high quality PVC boots welded in.
The boots have been tested for slip resistance on ceramic floor with sodium lauryl sulphate solution (NaLS) and on steel floor with glycerol
Protection type OB FO E SRC.
Thigh waders have been made of waterproof, very strong new generation rubber, not demanding any special treatment.
High frequency welding makes seams stronger.
