SEVEN KINGS SAPHIR Polstar – Dense, Durable and Comfort-Focused
The SEVEN KINGS SAPHIR Polstar fleece .This model represents a premium balance of insulation and durability, using a dense fleece structure that retains warmth effectively during cold shifts. SAPHIR is soft against the skin yet robust enough to withstand daily movement, bending and lifting. It offers moderate reflective elements for visibility but does not follow strict high-visibility classifications, making it suitable for settings where comfort and warmth are prioritised over reflective category compliance. Its ergonomic cut provides full freedom of movement, which is essential for technicians, warehouse staff and maintenance workers who require flexibility. The SAPHIR fleece stands out for its long-term comfort and premium fabric quality, delivering excellent day-to-day performance.

SEVEN KINGS QUARTZ Polstar – Strong Thermal Performance with Visible Reinforcements
The SEVEN KINGS QUARTZ Polstar fleece. QUARTZ offers a slightly heavier insulating profile than SAPHIR, making it an excellent choice for colder indoor warehouses, semi-outdoor logistics areas, industrial halls and maintenance work where long periods of static standing can increase the feeling of cold. The model includes reflective elements for improved visibility during low-light tasks and adds reinforced paneling in areas prone to abrasion. These reinforcements increase life span and maintain fabric stability in high-contact environments. QUARTZ is ideal for workers in workshops, large distribution centres and industrial service roles where durability must meet advanced thermal requirements. Its design provides a good balance between insulation, endurance and ergonomic comfort.

SEVEN KINGS TOPAZ Polstar – Flexible, Lightweight and Ideal for Mixed Tasks
The SEVEN KINGS TOPAZ Polstar fleece. TOPAZ is the lightest and most flexible model of the three, designed for workers who frequently transition between indoor and outdoor zones or perform tasks that require unrestricted mobility. While it offers reliable insulation, its primary advantage is its lightweight construction, which allows easy layering under jackets or softshells without adding bulk. Reflective details increase visibility during warehouse tasks, evening shifts or technical checks in dim surroundings. The fleece’s material ensures breathability, preventing overheating during dynamic work. TOPAZ is well-suited for logistic technicians, drivers, electricians and warehouse operatives who need a responsive and adaptable fleece layer.

TOPAZ, on the other hand, is the most lightweight and flexible model, ideal for workers who move frequently between tasks and need a breathable fleece that won’t restrict movement. While SAPHIR works best as a universal premium choice, QUARTZ is stronger for colder or more intensive industrial tasks, and TOPAZ is ideal for dynamic workflows where mobility and layering flexibility are priorities.
