Mammut develops the world’s first laser fused jacket

At ISPO 2019, Mammut will be presenting a world first: the award-winning Photics HS Thermo Hooded Jacket – the first laser fused jacket. Consequently, the innovative, completely waterproof and breathable down jacket is ideal for extremely cold, windy and wet weather conditions (down filling: 750 cuin goose down). Mammut is significantly involved in the development of the technology and owns the world’s first and so far only production facility for textile laser welding. The Laser Fuse device is located at the headquarter in Switzerland (Seon), where the first limited edition (500 pieces; B2C only) is developed and produced.

Mammut’s latest technological innovation has the potential to revolutionize the production of down jackets. With Laser Fuse Technology, materials are joined without adhesive to create seamless isolation zones. A completely new production facility for textile laser welding has been developed for this purpose, enabling an unprecedented production method: the laser penetrates through the outer, laser-transparent textile layer and hits an absorbing layer that converts the light into heat. This brings the joining spots into the range of their melting temperature, which are then connected by mechanical pressure. By doing so, the outer layer and the inner layer of the jacket can be connected without visible seams. In addition, the new laser machine allows complete freedom of design. Different sizes of insulation chambers can be welded together and therefore allow different filling quantities to be placed as required. Furthermore, there is no loss of down thanks to quilting seams without pinholes. The new product incorporates an innovation process of more than two years.
