Keslars Dark and Dirty Pink

Very similar in style to the Thread Frenchie, Tungsten Torpedo, Silver Bullet Baetis and other current 'euro' style nymphs, this pattern from Josh Keslar of Pennsylvania is designed for off-color water situations. 

Here's what Fulling Mill has to say: "Josh Keslar knows a thing or two about catching fish in tough conditions. This pattern was developed for just that. Dark, dirty or muddy waters… for some reason this bug stands out and continuously nets fish."
