The FKM Active Band Pro utilizes an advanced hybrid construction combining waterproof leather with an inner layer of FKM material. The leather is permanently bonded to an elastomer, achieving both a classic look and high functionality in demanding conditions.
This combination of materials ensures versatility – the strap retains its structure both during physical activity and everyday use. The entire band has been designed as a unified system, with each element performing a specific technical function, without compromising durability or aesthetics.
Waterproof Heinen Leather: The leather has undergone a specialized tanning process that infuses its structure with natural oils. This gives the material hydrophobic properties without the need for surface protective coatings.
The leather not only repels water but also retains its properties when exposed to sweat or dirt, which can be easily removed without affecting the material's structure. This process ensures the durability of the waterproof properties throughout the entire material, not just on its surface.
As a result, the strap maintains consistent performance throughout its lifespan, regardless of the conditions in which it is used. FKM Inner Layer: The inner layer of the strap is made of FKM fluoroelastomer, a material used in environments requiring high chemical and mechanical resistance.
FKM is characterized by high elasticity and structural stability, which translates into comfort and durability of the entire structure. Additionally, the inner surface is equipped with a microstructure that improves contact with the skin and supports stability during wear.
This material is resistant to easy wear, even with intensive use, making it a suitable choice for solutions with increased requirements. The use of FKM is an integral element of the design, responsible for the strap's functionality in dynamic conditions.
FKM Ventilation Channels: The internal structure is supplemented with holes that wick away moisture and improve airflow between the strap and the skin. This solution reduces the accumulation of sweat and water during use, directly impacting comfort and stability.
The holes are an integral part of the FKM layer and have been designed to not weaken the structure while simultaneously supporting its functionality under conditions of increased activity. This allows the strap to retain its properties even during intense contact with moisture, and its design allows for quick cleaning by rinsing with water.
316 Steel Elements: The strap features fastening elements made of 316 stainless steel, including the hooks and buckle, manufactured using metal injection molding. This process allows for high precision and dimensional repeatability, resulting in a stable fit and durable connections.
316 steel is characterized by corrosion resistance and high mechanical strength, which is important in the context of contact with moisture and external factors. The entire design takes into account high manufacturing tolerances, which influences the aesthetics of the construction details.
Water-resistant Construction: The entire strap structure has been designed to be fully waterproof. The materials used and the method of joining them allow for direct contact with water without affecting performance.
The strap can be cleaned by rinsing, allowing for the quick removal of contaminants accumulated during use. The structure is designed as a cohesive system, with each component maintaining its properties.
