Mesh made of plastic is originally used for various purposes, from embroidery (very fine) to aquaristics (medium) to sound-damping.
For fursuits it is often used for larger even or slightly bent areas of the head.
The advantages are:
- Hot air from the inside can pass it way better than foam.
- It doesn't rust.
- Various sizes and degrees of hardness
- The covering fur can be glued on without baring the advantages above.
Alternate names include: Plastik-stramin (german), wash basin inset
