UTC Antron Yarn 

Add subtle sheen, buoyancy, and durability to your fly patterns with UTC Antron Yarn, a synthetic trilobal nylon fiber that's become a fly tying essential. Spooled for easy dispensing and storage, this versatile material is ideal for crafting wing posts, trailing shucks, bodies, legs, and even dry fly wings.

Antron yarn’s natural translucence and sparkle mimic the look of emerging insects, making it a favorite for emergers, parachute posts, sparkle duns, and nymphs. Its spooled format keeps your bench tidy while offering maximum control and consistency.
