Satisfy FuzzFleece Octa Long Tee - Japanese Hollow-Core Insulation for Shifting Effort and Climate

Insulation and airflow take on new dimension. 169 grams of FuzzFleece™ Octa® fabric built from Japanese hollow-core fibres that trap heat in their structure whilst keeping weight minimal. Reversed panelling exposes the textured side in high-heat zones for natural airflow regulation without sacrificing insulation. A quiet system of breathability without compromise.

FuzzFleece™ Octa® Japanese Hollow-Core Fabric

FuzzFleece™ Octa® is a Japanese bi-component knit built from hollow-core fibres. Heat is trapped within the fabric's structure whilst weight is kept minimal at 169 grams total. Fast-drying and moisture-controlling properties manage output across varied effort levels, light enough to disappear in motion.

Reversed Panelling for Ventilation Where It Counts

Reversed panelling exposes the fabric's textured side in high-heat zones through the back, sides, and underarms — precisely where natural airflow opens during running. This construction regulates temperature without sacrificing insulation across the rest of the garment. A considered system that breathes where you need it and retains warmth where you don't.

Ergonomic Construction with Clean Internal Finish

Anti-chafe flat seam construction eliminates irritation across extended efforts. Ergonomic cut flows seamlessly with your stride. Reflective Satisfy logo centred at front. Fully detachable care label on the outside — nothing inside that shouldn't be.

Is the FuzzFleece Octa Long Tee Right for You?

Built for runners who move through shifting effort levels and temperatures and need a single layer that adapts rather than requiring a wardrobe change. The hollow-core Octa® fibre structure traps heat without the weight penalty of traditional fleece, whilst reversed panelling at the back, sides, and underarms opens ventilation precisely where body heat concentrates during effort. The result is a layer that keeps you warm during easy efforts and breathes during harder ones without needing adjustment. At 169 grams it genuinely disappears in motion. Anti-chafe flat seams and ergonomic cut keep things comfortable across extended runs. If you want a long-sleeve layer that handles the full range of a variable outdoor run without compromise, the FuzzFleece Octa delivers it quietly and without fuss.
