What is thermal insulated fabric?
Thermal insulated fabric is designed to retain body heat and provide warmth in cold conditions. It achieves this through a combination of materials and structures that trap air, which acts as an insulator.
How Octa® fabric is different?
Octa® filament has an octopus-like cross-section with 8 projections, which create air gaps that enhance heat shielding and insulation properties. That unique fiber structure makes Octa® fabrics roughly 50% lighter than regular polyester materials of similar thickness.

Active Insulation Material
Active insulation regulates body temperature and wicks moisture during physical activity. Octa® keeps you warm without sweat or chill, thanks to its superior moisture absorption and diffusion from its eight projection filament yarn
Customized to meet different needs
By customizing the knit construction, we offer a diverse range of weight options(70-300gsm) to meet breathability requirements.
Additionally, the new non-brushed type minimizes fiber shedding, further reducing ocean microplastic



Wicking maximized by capillary effect
The Octa® fabric uses low-count continuous polyester filaments. However, its unique 8-fin cross-section increases the fabric surface area, enhancing wicking through capillary action and
channeling water away for quick drying.
Heat Retaining Fiber Technology
Dead air forms in the gaps between each Octa® filament’s 8-fin projections, trapping and retaining body heat while prevent overheating with its highly breathable structure.
“Weightless warmth made possible with Octa®”


Every day
Outerwear and pants lined with Octa® brushed type fabric are airy, lightweight, and easy to carry. The moderate stretch provides extra comfort for daily wear, not just for extreme outdoor scenes.

Cycling
Cycling often leads to heavy sweating. Octa®’s moisture-wicking properties quickly absorb and expel sweat, reducing discomfort. Its breathability prevents heat buildup and overheating.

Mountaineering
In mountaineering, where weather changes and significant temperature drops are common, Octa® controls sweat and enhances insulation, making it ideal for ever-changing environments.
Product Listing
Octa® CPCP / Brushed
Utilizing hollow 8-fin cross-section Octa filaments, this functional tricot fabric seamlessly integrates padding and lining. By trapping a substantial amount of air, it achieves both lightweight and high insulation. Unlike traditional fiber filling, this tricot fabric prevents fiber leakage or shifting of the padding, allowing for unrestricted product design
Octa® Thermofly / Non-Brushed
The new structure features a unique, bulky plush design without brushing. It’s a double raschel knitted fabric precisely cut in half. The middle nodes use Octa, Teijin Frontier’s advanced hollow-core fiber with eight radial fins. The fabric incorporates a special dyeing technology to enhance Octa’s crimping and stabilize its plush structure. This results in exceptional comfort, with heat insulation (lightweight bulkiness and warmth) and yarn tips on the skin side that evenly absorb sweat and dry quickly
