We divide our Garment-System into Parts and Layers.  Parts are Hoods [HO], Collars [CL], Cores [CR] (upper body), and Sleeves [SI] / [SR]. Layers include the Shell, made out of the Parts mentioned above, and Insulations, integral garments that connect to the Shell as a Liner.All Parts exist in various designs and are modular. We utilize custom made lightweight zippers with high flexibility to facilitate the compatibility of all Parts while guaranteeing the performance of our jackets. The cross-combination of these various design options allows you to continuously adapt your outerwear to changing needs, desired appearances or unexpected situations. Adding additional Layers to your Garment-System extends its usability beyond aesthetics across seasons. All Parts and Layers have specific capabilities and functions. The more Parts or Layers you have in your System, the more capable it will be.
