If you mean “fly krystal” as krystal flash for fly tying, the best matches are the flash materials: Snake River Fly Krystal Flash, Hareline Krystal Flash, and Orvis: Quality Clothing, Fly-Fishing Gear & More Since Krystal Flash Wing Material. They’re used to add sparkle, visibility, and movement to streamers, buggers, Clouser-style flies, and small nymphs.
If you want a finished fly or kit that already uses krystal flash, Postfly Fly Tying Kit | Clouser Chartreuse is a strong baitfish-pattern option, and Postfly Fly Tying Kit | Heisenberg Articulated Streamer is a bigger trout streamer kit with krystal flash in the materials.
