Fulling Mill Ultra Dry Yarn

Fulling Mill’s Ultra Dry Yarn is a revolutionary synthetic material designed for fly-tiers who need exceptionally buoyant and durable dry fly wings, posts and shucks. It is the ultimate solution for flies that must float high and remain visible in any conditions.

With a legacy spanning over six decades, Fulling Mill is one of the world’s leading manufacturers of premium fishing flies, and fly tying materials. Based in the UK, the brand has built its reputation on a foundation of quality, innovation and an unwavering commitment to the needs of serious fly anglers. Their products are trusted by enthusiasts and professionals alike globally.

The secret to Ultra Dry Yarn lies in its specialised manufacturing process. Unlike standard yarns, this material is not just a synthetic fibre, it is engineered from the ground up to be water-repellent. The fibre undergoes a unique hydrophobic process during production that permanently seals the yarn, totally preventing water absorption and ensuring they remain light and buoyant.

This innovative yarn is incredibly fine and light, with a texture that is a pleasure to work with. Its hydrophobic properties means it sheds water instantly and never becomes waterlogged, keeping you flying high or surface film. This material’s durability ensures that your fly will withstand multiple fish and casts without losing their shape or buoyancy.

Fulling Mill Ultra Dry Yarn is also available in a range of highly visible, fluorescent colours, which make your fly easy to spot from a distance, even in low light or on fast-moving water. It comes in generous packs of yarn, providing ample material for dozens of flies.
