The Greenpeace fly, or Grænfriðungur as the name is in Icelandic, was originally designed by Kristjan Gislason and has since the beginning been a firm favorite for many anglers in Iceland.
A truly elegant hitch tube that has proven to be excellent as Grænfriðungur is extremely generous in salmon fishing.
The hole is in the middle of the tube and as such it floats 100%.
