Many mayflies around the globe are approximate 3/8 inches (10 mm) in size. During the dun stage plenty of these will have a transparent, almost dull grey color. And that is why you should have a couple of these in your box. We recommend that you use a J:son Swivel for all your fly fishing, no matter what type of fly you are using. However, it is necessary to use a J:son Swivel whenever you fish a size 1 or 2 J:son fly.
Size: 10 mm / approx 3/8 in. Hook: J:son SS.DF #22
