Super HD EVA Foam Blocks

Upavon Super HD EVA Foam Blocks are high-density closed-cell foam in block form — 30% denser than standard craft foam alternatives, which means cleaner cuts, more precise cylinder shaping, and bodies that hold their form under thread pressure without compressing flat. Use them with the Gunville Foam Cutters to produce consistent cylinders for hopper bodies, Cranefly abdomens, large dry fly bodies, popper heads, and surface lure patterns where foam density directly affects buoyancy and durability.
