Semperfli Flat Fly Tyers Foam

Closed Cell Foam Sheet — The Material That Revolutionized Dry Fly Tying

Closed cell foam changed the game for terrestrial and dry fly tyers. Nearly unsinkable, endlessly versatile, and easy to cut and shape at the vise, it opened up a whole new world of realistic fly patterns that ride high on the surface no matter how rough the water gets. Whether you're punching out hopper bodies, stacking beetle shells, or building realistic ant patterns, this foam delivers the buoyancy and durability that natural materials simply can't match.
