6mm Fly Foam is a valuable and durable material that is perfect for creating realistic, buoyant bodies on different types of fly patterns. It is excellent for crafting foam terrestrials, poppers, and other topwater flies, as it adds superior floatation and structure. With its easy shaping and cutting, 6mm Fly Foam is a must-have for the creation of highly effective, buoyant patterns for both fresh and saltwater fishing.
