When effort spikes, warmth adjusts. 158 grams of Octa® bi-component knit tuned for the swing in the body’s condition. A half-zip front turns temperature control into a single motion.

Antoine is 188cm/6.2’ and wears a size M.

Octa® is a Japanese bi-component knit built from hollow-core fibers that trap warmth while keeping weight down. The structure wicks moisture and dries fast, holding its insulating power through sustained effort.

The front zip opens fast, releasing heat the instant pace lifts, then closes to hold warmth when effort settles.

Reversed paneling exposes the fabric’s textured side in high-heat zones through the back, sides, underarms. Where natural airflow opens and regulates temperature without sacrificing insulation.

Flat-seam construction, mapped to movement. An ergonomic cut sits close through the shoulders and follows the arm's natural swing.

Reflective SATISFY logo, centered.

Stealth-reflective ©SATISFY logo, for catching light in the dark.

Fully detachable care label on the outside. Nothing inside that shouldn't be.

Usage

Technology

- Fuzzfleece Octa®

Octa® is a Japanese bi-component knit, engineered with hollow-core fibers that capture warmth while keeping weight minimal. Its structure wicks moisture and dries almost instantly, sustaining comfort through effort and exposure. Our engineering reimagines the fabric, reversing its placement in key zones so the textured side faces outward where heat builds most. Along the back, sides, and underarms, these raised channels open natural pathways for air, releasing excess while preserving insulation. A half-zip front adds a second layer of control, letting temperature adjust in real time.
