D&L Diel starts off as a daring enterprise of a family, where skiing is everyone’s passion, aimed to design and produce exquisite ski wear. 

The new company begins with five sewing machines and two original models – men’s and ladies’ overalls. The designs are impressive and the first orders start coming in.


Inspired by the favorable beginning, the company meets the new season with sixteen new models. After intense research Diel’s own fabric is developed, stamped with fancy up-to-date original patterns.

The first participation in a leading international exhibition - ISPO Munich – turns out to be a great success for Diel’s genuine brand and product.


Diel opens its own factory – an important step on the way to the foreign markets through constantly increasing production capacity and quality.

The first international order is coming from Slovenia, this first move abroad is quite successful and Diel’s apparel is well known and accepted in that country up to now as the brand is the official sponsor of the Slovenian Ski Pool and Slovenian National Children’s Ski Team.


Diel becomes sponsor and exclusive supplier of the official apparel of the Bulgarian Olympic delegation for the Winter Olympics in Nagano. This means prestige, but also a lot of effort and resources. The outfits are made to measure for each contestant individually.

In the century’s last Olympic Games Ekaterina Dafovska triumphs on the Olympic ladder dressed in Diel’s outfit. She wins the 15km biathlon race and becomes the first Bulgarian athlete to conquer the White Olympia.


Diel levels up to the high demands of the world users. The new models are made of high-tech fabrics, breathing and waterproof, revolutionary innovation at the time. 

Diel clothes the Bulgarian Olympic delegation again for the Summer Olympics in Sydney. The response is more than good and letters of appreciation from the Bulgarian Olympic Committee, sports federations, eminent sportsmen and journalists shower on Diel. Twelve Olympic medalists rejoice with Diel’s outfits.



At the Winter Olympics in Salt Lake City Diel’s outfits climb the winner’s podium with Bulgarian athletes Evgenia Radanova (shorttrack) and Irina Nikulchina (biathlon) three times and receive a prize from the sports journalists for the most beautiful and functional apparel at the games.

Diel is awarded the medal "The Sport for a Peaceful World" for contribution to the Bulgarian sport and the Olympic movement. This year Diel also sponsors the Bulgarian National Ski Team.



Diel Sport conquers the Antarctic and remains there as the professional cold-protective wear of eightteen consecutive missions of the Bulgarian Antarctic Institute and for the future.

The brand starts working with a professional communication agency and creates memorable advertising campaigns.

Diel is growing. The administration moves to a new headquarters together with the design crew. Innovative CAD/CAM system is introduced for the development of the new models.


Winter Olympics in Turin. Bulgarian Olympians like Diel’s sports outfits so much; they decide to march in the opening procession with them, rather than with the official ones, as the tradition demands. Evgenia Radanova wins the silver in the 500 m short track.
