Winters are cold. The high heating cost in Korea makes people feel even colder.
This campaign ran from Nov. 4 until Dec. 31, 2016 in all 189 Uniqlo stores in Korea.
A Heat Tech Window was given for free with each purchase of a Heat Tech thermal wear product. 500,000 people were given a Heat Tech Window, which was then applied to their window at home.
The campaign video reached 30 million impressions online.
As a result, Heat Tech sales recorded a year-on-year growth of 203%.
This winter, homes with the Heat Tech Window were able to save about 20% on heating overall.
