Hareline Krystal Flash

The Original Sparkle Maker

Krystal Flash is the OG of flash materials—the one that started it all and still hasn't been dethroned. For decades, tiers have been adding strands of this stuff to flies because it does exactly what it promises: makes fish look twice, then strike.

Why It Works

The magic is in the simplicity. Krystal Flash is fine, flexible, and catches light like it's getting paid to do it. A few strands mixed into a wing or tail creates just enough sparkle to suggest scales, gills, or that indefinable "aliveness" that turns lookers into eaters. It moves naturally in the water, doesn't overpower your pattern, and fish have been falling for it since before you started tying.

Perfect For

• Streamer Wings: Add lateral lines to baitfish patterns without the bulk
• Nymph Tails: A few strands turn a basic nymph into something worth chasing
• Wet Fly Accents: Classic patterns with a modern flash upgrade
• Saltwater Flies: Shrimp, crabs, and baitfish that catch light underwater
• Steelhead & Salmon: Wing accents on intruders, spey flies, and egg-sucking leeches
• Bass Bugs: Because largemouth bass are basically underwater magpies

How to Use It

Less is usually more with Krystal Flash. A few strands mixed into a wing or tied as a tail is often all you need. Too much and you've got a disco ball; just right and you've got a fly that looks alive.

Available in every color you need and several you didn't know you wanted.
