Made to endure
The majority of materials we use for our commercial production are the same which we use in equipment for the Finnish Defence Forces and other defence and security clients. Our most commonly used fabric in load carrying equipment is extremely wear resistant 1000D Cordura, as per FDF specs, with polyurethane coating on the inside. The webbing and edge tape we use are, again as per FDF specs, strong polyester webbing in various widths and thicknesses for different applications.
Our green and M05 camouflage materials and accessories are by default compliant with strict FDF specs for NIR reflection levels, as should be since these same materials are used in official military equipment.
