Caster's Squirmito is the original fly tying material for tying one of the most effective fly patterns, the Squirmy Wormy!  These long, skinny, and squishy strands of silicone create a lifelike movement in the water that imitate real worms. Looking to tie up an alternative to the San Juan Worm with a more realistic look and squirmy movement, try Caster's Squirmito and see just how much the fish love it.
