Rigging a size 24 gnat to 7x tippet with your bare fingers and naked eye is a badge of honor. We get it. But fingers get cold, light gets bad, hands and eyes get tired. The Fly Roost is here to help! The Fly Roost holds your fly in place, guides your line through the eye of the hook, and spins to help you finish the knot. The Fly Roost lets you easily thread and knot your fly no matter how small the hook or how frozen the fingers. The Fly Roost works with most hooks and fly types from size 6 down to size 24.
