Dryflies or Skaters as I prefer to call them.
They are fished stripped on the surface and the mark they make on the surface appeals the fish that often take the fly very hard. 
Body off thick deerhair with rubberleggs. Backshield from foam. If you like to fish them hitching, just make a knot with the leader behind the plasticcone.
Skaters are avaliable in sizes 3 & 5cm
Price 6,6€uros/each
