These briefs have a laced pouch made from soft cowhide nappa leather, to which a flap can be attached with press studs.
The butt straps and the side straps are made of sturdy, 2.1 to 2.3 mm thick cow split leather and can be adjusted with buckles.
Sorry, the cuffs and harness shown are not included.
