History
Ajungilak originated in 1855 as Fuglesangs Sønner AS on the Akerselva river in Oslo. The company was established as a textile enterprise and initially manufactured insulation and building materials. It was described as Norway's ninth textile company. Insulation was part of the operation from its beginning, and in 1890 the company began applying this capability to sleeping-bag production. Sleeping bags subsequently became the business's best-known product and the main source of its connection with the outdoor-equipment industry. The factory was renovated in 1947. In 1960, the company began exporting sleeping bags to European markets through the Helly Hansen distribution network. A new factory was built in Hønefoss in 1963, and from 1970 that location served as the company's sole production site. International expansion continued with the opening of a United Kingdom department in 1973 and a factory in Milton Keynes in 1979. The corporate name Ajungilak A/S was formally adopted in 1980, the same period in which the company established a factory in Hamburg. In 1991, the business grew through the acquisition of Nordiska Fjäder AG in Malmö. Production was later reorganized internationally: in 1999, the entire production line was moved to China, while design and development remained in Norway. This preserved a Norwegian development base while shifting manufacturing away from the company's historic domestic facilities. Mammut Sports Group Ltd. acquired Ajungilak in 2001. Mammut was part of Conzetta AG's holding structure, and the transaction integrated Ajungilak into a larger outdoor-equipment group. Public information does not clearly establish whether Ajungilak continued as a separate operating company, when independent production ended, or the extent to which the name remains in current commercial use. The brand is therefore best documented as a historically significant Norwegian sleeping-bag and insulation business with an uncertain present status.

Outdoor equipment · 1890
Sleeping bags
Sleeping bags became Ajungilak's signature product after the company began manufacturing them in 1890. The category applied the company's earlier insulation expertise to camping, trekking, mountaineering and other outdoor overnight activities. Historical materials identify sleeping bags as the principal product through which Ajungilak developed its international market presence, including European exports from 1960 onward. Specific current models, technical specifications and product status are not established by the available reference material.
Building and textile materials · 1855
Insulation materials
Insulation was manufactured from the company's establishment and formed the industrial basis for its later sleeping-bag business. The available historical account places insulation and building materials among Ajungilak's original activities, but does not provide a detailed catalogue of materials, applications or later product names.
