For Fall/Winter 2025, Blue Monte has adopted Teijin Frontier's high-performance material Octa® as its main material in pursuit of "lightness, warmth, and comfort."
Insulation, quick-drying properties, and ease of movement are all essential for outdoor wear.
Octa® was our chosen answer to achieve all of these in a single garment.
What is Octa®?
A unique, multi-lobal polyester fiber with eight protrusions, in addition to a hollow structure.
This innovative material simultaneously achieves lightness, breathability, and warmth through its special octopus-leg-like structure.
Hollow fiber + 8 "legs" → creates an air layer, making it light, warm, and quick-drying.
Why Octa® is superior
■ Surprisingly Light — Lightweight
Approximately half the weight of ordinary polyester of the same thickness.
Provides stress-free comfort even with multiple layers in fall and winter.
■ Comfortable even when sweating — Moisture-wicking and quick-drying
The hollow structure and radial protrusions quickly absorb and disperse sweat.
Prevents "sweat chill" common in winter activities.
■ Traps air for warmth — Insulation & Heat Shielding
Retains "dead air" (still air) between the hollows and protrusions of the fibers.
Achieves light yet warm, ideal insulation for winter.
■ Adapts to movement — High Breathability
Even with its thickness, it prevents stuffiness.
Comfortable for both outdoor scenes and urban use.
