1. So, what is the difference between these masks?
All Triplette masks are approved by the FIE, and pass the 12 kg punch test required by both the FIE and the SCA. That test measures how much force is required to spread the wires in the mesh, and another factor of mask strength (and thus durability) important to SCA fighters is dent resistance. The mesh in the 183 will dent a little more readily than the 1999, and the 2000 is the strongest mesh available. This is the SAME mesh used in our FIE Homologated mask, and its production qualities are so strictly regulated by the FIE that ALL such meshes are essentially identical.
The 183 has a vinyl liner, where the 1999 and 2000 have removable, washable flannel liners.
The 183 bib is un-rated, the 1999 tests at 400 newtons, and the 2000 at 550.
Our recommendation for SCA fighters is the 1999 or 2000. These stand up well against the impact of schlagers. We do not recommend the 183 in schlager competition.
