Chinook Wind Outfitter's Glacier Flash comes in amazing colors. It's 1/69" in width with the supported having 2 supporting threads in addition to the main colored thread and has approximately 250 strands and 19" in length giving you lots of material to tie with. The unsupported simply has the main strand with no supporting threads at all.
Glacier Flash can completely replace other flashes in your tying boxes and is strong so if you nick the hook, it will not instantly break like some other flashes. Use it on your wet streamers or as the wing on a Wulff pattern or replace the wool on a Red Tag with it. Tie in the UV colors in your big salmon patterns or make the popular Kreelex Fly in various colors. The uses for Glacier flash is only limited to your imagination.
Please look at the picture as it will show you the exact style of the flash. Some is supported meaning it has one main thread with two miniscule threads around it adding bulk while unsupported flash has only one main flat thread with no bulkiness.
