RIO's bass leaders are designed and built to match the needs of the bass
 fly fisher. The leaders are made of a medium stiff nylon and have a 
powerful taper design that will easily turn over large flies, and cope 
with tough winds. The copolymer material is incredibly tough and 
abrasion resistant.
