Surfwear brand Rip Curl is accused of using factories in North Korea, where the conditions are reminiscent of slave labour, to create the company's 2015 winter apparel line.
Workers at the Taedonggang Clothing Factory near Pyongyang, North Korea's capital, were photographed in July 2015 making the Australian company's garments, according to The Sydney Morning Herald.
The heavy jackets and pants were then sent to retail stores around the world, reportedly bearing "Made In China" tags.
School children through to university students are often forced to work in North Korean factories for more than 20 hours a day and are paid very little, if at all, according to the Humans Rights Watch.
"The harsh reality faced by North Korean workers and students is unpaid forced labour and exploitation," deputy Asia director at Human Rights Watch Phil Robertson said. "Those who refuse face being sent to forced labor camps where they must do hard labor, face physical abuse from guards, and are treated as less than human."
