Beginning as a liquid, microscopic cells are poured into a mold then polarized so each cell lies end to end creating a tunnel. Another layer is poured on top and polarized in a new direction, this process is repeated hundreds of times creating a honeycomb matrix allowing impact and heat to move laterally like rings of water when you throw a stone into a quiet pond. So impact and pressure is dissipated ACROSS ThinLine! Just watch the golf ball test!
