Ultra Thread is a specialized fly-tying thread engineered for superior performance. Made from nylon, it provides better stretch and grip than polyester, allowing more uniform tension and durability. Its flat, minimally twisted design reduces bulk, ideal for small flies and precise tying. Light waxing gives it a smooth texture and enhances durability when head cement is applied.

Packaged on smooth-turning spools with color-coded caps, Ultra Thread is designed for optimal handling and identification.
