Calf hair is a fine, solid & very durable material that will not flare. It is typically used for wings on dry flies such as the royal wulff & parachute posts on many more.... The extra process leaves the calf tails very clean of dye & natural oils. Beautifully dyed, even to the roots. Because of the crinkled texture, calf tail has the ability to trap air between the fibers & is excellent winging material for large dry flies. You will find them a pleasure to use!
