Stones of Warmth

It is quite common for Koreans to use hot stones for warming themselves during harsh winters. Keeping this in mind, we have here the ST-ON concept, which is a stone warming unit for mountain climbers. When the stone-shaped units are fully charged and warm, they turn orange and start radiating heat when removed from the charging unit. They keep you warm during your mountain climb, but I reckon anyone with cold feet can use this.
