Spirit River UV2 Mallard
Spirit River UV2 Mallard is a loose fly-tying material made from mallard feathers. Individual feathers vary in length, shape and fibre layout, allowing each piece to be matched to the construction. They work well for wings, tails, sides and contrasting pattern accents. A feather with an even profile helps form a clean wing, while the fibre arrangement can be selected to suit a tail or side detail. The UV2 finish increases colour visibility in the ultraviolet range.
Construction and use
Select each feather according to its role and the proportions of the fly. A wing benefits from an even profile, while a tail or side detail depends more on the direction and arrangement of the fibres. Align the fibres before tying and secure the feather in controlled sections with moderate thread tension. This preserves the shape of the delicate material during construction.
