A slightly kinked poly material that floats so it makes a wonderful material for use in terrestrials underwing, as a caddis wing or even as a spent wing material for those tricky Trico spinner falls in late summer and early fall. This product really shines as a parachute post material in that it floats like a cork and has a small size when compressed and tied into a pattern.  Some anglers have even used this material to construct micro indicators due to its' light weight and bright colors.
