The Loon Outdoors Rigging Foams are designed to streamline your fly fishing experience by allowing you to pre-rig multiple setups before hitting the water. These sturdy, reusable foam housings securely hold various configurations, including multiple nymph rigs, dry-dropper setups, or single dry flies on a leader, facilitating quick and efficient changes during your fishing sessions. Sized identically to common tippet spools, they integrate seamlessly into your existing gear, minimizing waste and maximizing time spent fishing.
