A fabric made of polyamide fibres, coated with a layer of Teflon, renowned for its extraordinary resistance to adverse external factors. The fabric is lightweight, waterproof and very durable. It is used in the manufacture of specialised clothing and footwear, but also backpacks, harnesses and protectors.

A material used in Smith helmets that provides a high level of safety. It is characterised by a cylindrical structure that absorbs energy during impact and transforms it into kinetic energy, but does not give it back, as is the case with materials that act like a spring. In addition, thanks to their construction from small tubes, they are well permeable to air.
