Have you ever wondered where the kites you use are made? How is a kite made? In an attempt to answer these and other questions, our friends from Windsuf Spain decided to travel  to the factory from which the kites that Duotone kiteboarding markets. Maybe you are wondering where are Duotone kites made…  the old brand of North Kiteboarding changed to Duotone and they currently produce in Sri Lanka

Like many companies in the sector, the interest of Duotone, one of the leading companies in kiteboarding, does not focus only on the number of kites sold each year, its priority list includes product quality and willingness to technological innovation. During their visit, the managers of the factory showed them, in addition to its magnificent facilities, the process that is followed for the manufacture of a kite.

It was not until about few years ago that the company’s management decided to move the factory from China to Sri Lanka. The reason for the change was the difficulties that foreign companies in China encountered in running their own companies. This regulatory framework forced companies like Duotone to find local partners to deal with these limitations imposed by the Chinese government. The legal structure made it difficult to ensure the quality and set the prices of each product.

Strategically located between Europe and East Asia, production costs and quality in Sri Lanka do not differ from those of China. These factors have determined the relocation of several factories in the kite sector. In Sri Lanka, Duotone has found the support of the Austrian company GSL and the German company Aqua. During the visit they had the opportunity to see first-hand the GSL factory facilities, where a total of 360 employees work. These are responsible for the production of six models of kites for five days a week in nine-hour shifts. In total 100 kites are manufactured per day, representing 85% of Duotone total production. The production is divided into 10 sections, each with its own team leader and quality managers. From the fabric cutting process to shipping, a kite goes through seven independent quality controls. Duotone places great emphasis on the quality of each of its products. High-tech production techniques are used in two areas of the chain. For the initial cut of the fabric alone, 150,000 euros have been invested in a state-of-the-art machine. Computer controlled sewing machines are also used, which reinforce the critical areas of the kite that have to withstand significant stress (valves and gaskets). Most of the production is subject to high quality artisan methods. A good example of this is the thread, which is manually sealed individually. This level of attention to detail is what determines the production of a high-quality product versus a low-quality one. It goes without saying that 44 hours of manual labour are invested in the manufacture of a 12 m2 Evo. To produce a kite (including production and quality controls), it takes a whopping three weeks of work.

Duotone kites are produced in Sri Lanka, under a very strict quality control. Below we detail the steps followed in the production of a kite:

  1. Body. Each section of the kite is obtained from large surface panels. The sections are sealed at the edges, while the reinforcing layers are sewn in the critical areas. To further strengthen the joints, in 2010 Duotone began gluing the layers together before sewing them together. With this it is possible to avoid blind spots, reducing the probability of minor errors.
  2. Tube. Six steps are required to mount a tube. After drawing the patterns 28 layers of material are stacked. Next, the valves and tubes are cut and joined. The tubes are then inflated to identify possible air leaks. The excess material is removed with the help of scissors and the tubes are inserted into the kites.


  1. Printing. The printing section has 40 employees. These work exclusively on the printing machines that GSL has produced specifically to meet NKB specifications. Up to eight colours can be used for each print. Due to wear and tear from sun exposure, sea water and sand abrasion, the use of resistant colours has become a science in itself. One of the stress tests is carried out in the GLS freezer. During our visit we witnessed the testing of a new colour.


  1. Small components. A kite is made up of more than 500 individual pieces such as reinforcements, valves, rubber hoses, brackets, and velcro pieces. A part of these components come from companies specialisedin each type of material.


  1. Final check. In this phase, each kite is inflated to verify that it can maintain constant air pressure. Kites that do not pass the control return to the start of production. Kites that pass the tests are immediately shipped to the 39 countries where Duotoneproducts are distributed.
  • A part from Duonoce, there are other kite brands that produce kites in Sri Lanka, like Eleveight kites, that are also made in Sri Lanka
