Today, drastic global climate change results in severe cold weather in northern Thailand. In 2014 alone more than 160 people died from exposure to cold weather. For that reason, Lay’s wants to deliver warmth in order to return happiness to Thai people.

My team at BBDO Bangkok designed “Sleep-in Lay’s” – the world’s first solar heated sleeping bag using Lay’s packaging. Because Lay’s packs are made from Aluminum foil, they are able to effectively retain air.

Once the sleeping bags are assembled, using black cloth, sheets of plastic and bottles of water, they are placed under strong sunlight during the day to imitate a “solar heating” process within each sleeping bag. This process creates a miniature “greenhouse effect”, effectively generating and increasing stored heat inside of the bags. Throughout the cold night as the bottles release the heat, the sleeping bags hold that heat to help keep the occupants safe and warm.
