Signal-Trim Thoracic Knit

The skin is the largest sensory organ in the human body. It is also the most ignored when selecting clothing.

Every fabric you wear sends a continuous signal to the somatosensory cortex. Most fabrics send a bad one. The scratch of synthetic jersey against the sternum. The low-grade thermal complaint of a fabric that cannot manage its own moisture. The body registers these as threat — small, persistent, subclinical. Cortisol accumulates. You do not know why you are irritable by midday. The fabric knows.

This knit resolves the dispute.

The body of the garment is a 75% merino wool / 20% silk / 5% cashmere blend — a composition that the nervous system experiences as neutral. Merino's fibre diameter is engineered below the itch threshold (under 18.5 microns). The silk fraction reduces surface friction. The cashmere fraction increases loft — the yarn traps a micro-layer of air against the skin, regulating temperature without the heat build-up that triggers thermal stress responses.

The moisture-wicking mechanism is physiological, not chemical. Merino wool absorbs up to 30% of its own weight in moisture vapour before it feels damp — drawing perspiration away from the skin surface and releasing it into the air. In summer, this prevents the cycle of damp, cool, clammy, irritable that synthetic fabrics accelerate. The body maintains a stable thermal environment. The nervous system does not need to issue a complaint.

The highlighter yellow contrast trim at the waist is a signal. Not decoration. The body requires clear spatial anchors — proprioceptive cues that locate the physical self within its environment. The trim provides a visual boundary. The waist is confirmed. You are located.

The glow-in-the-dark SOME DOSE sigil on the chest operates on the same principle as the cranial variant: vital energy, externalised. Solar-charged. Released after dark. It is a private marker for the cognoscenti and a low-lumen reminder that the body continues to function after the building empties.

This is not a summer garment in the seasonal sense. It is a summer garment in the neurological sense: a thoracic layer that refuses to make the heat worse, refuses to irritate the surface it covers, and refuses to be noticed until it is removed.
