Polyester filaments, from which a lightweight, heat-storing lining fleece is made.
Double 'D' ring buckle
Refers to a buckle (e.g. on helmets) in which a strap is pulled through 2 D-shaped eyes in order to regulate the length. To open the buckle, the strap must be pulled back through the eyes, and therefore the length adjustment is lost and must be repeated the next time the helmet is used. A little time is needed to thread the belt, but then it is very easy to adjust and always perfectly tensioned.
Double-shield visor
Two visor shields, bonded together by a layer of silicone between them. The silicone layer creates a thermal effect similar to the double glazing of a window pane. The result is 100% freedom from fogging.
Dry-Cool is a synthetic fibre. When it comes into contact with the skin, the skin's moisture is absorbed by the material - so your skin feels comfortably cool. As a result of the water-absorbing particles in the fabric, sweat and moisture are only absorbed by the surface of the material, where they quickly evaporate - the Dry-Cool surface therefore has a quick-drying effect.

Dynatec Reflex
This special fabric from Schoeller gives you active and passive safety combined in one product: abrasion-resistant Dynatec, woven together with 3M Scotchlite, shines in the dark, and offers increased protection in the event of an accident. Dynatec material brings a genuine improvement in safety, particularly for fans of traditional, black motorcycle clothing, without impairing the appearance.

Advanced nylon fabric made of particularly strong, closely woven yarn. Good resistance to abrasion, extremely hard-wearing. Widely used for protective reinforcements due to the strong material structure. Dirt-repellent finish. Robust, textured fabric appearance.

Dyneema was originally used as a competitor to Kevlar. The material consists of polyethylene fibres that undergo numerous manufacturing stages in order to achieve high UV resistance, very low stretch, outstanding breaking loads, high strength, light weight and high durability. Amongst other applications, Dyneema is used to make sails and tear-resistant cords. The material is also extremely suitable for glass fibre multi-laminate products, e.g. surfboards and motorcycle helmets.
