What if one of the cells in the synthetic ice core gets punctured?
All the materials are non-toxic and each cell is completely sealed off from the others. The vest is over-engineered and will perform perfectly with as many as ten punctured and empty cells in the core. So if one cell breaks, the rest are still working and the HeatShield remains completely functional. If you need to stay cool when you’re working or otherwise in a heated situation, the HeatShield cooling vest is a great choice.
