300GSM · 100% Cotton
EVERYDAY / STRUCTURED / SUBSTANTIAL

CORE//WEIGHT™ is DAY//ONE's signature heavyweight cotton fabric, built around structure, substance and an elevated hand-feel.

At 300 GSM, it carries significantly more body than a conventional lightweight tee, creating a substantial feel and structured drape. Soft against the skin while retaining enough body to hold the oversized DAY//ONE silhouette.

Made from 100% cotton, CORE//WEIGHT™ balances its heavyweight construction with the natural comfort and breathability of cotton. The result is a tee that feels substantial in hand, structured when worn and designed for repeated everyday wear. Designed to be worn hard, worn often and lived in.

Plain
The cleanest expression of CORE//WEIGHT™. A smooth, heavyweight cotton base designed to give the black and white AFTER HOURS pieces a structured, premium silhouette.

Acid Wash
The same 300 GSM CORE//WEIGHT™ cotton, transformed through an acid-wash treatment that creates tonal variation and a worn-in character across the garment. The washing process means natural variations in colour and appearance should be expected, making each piece unique.

250 GSM · 100% Polyester
LIGHTWEIGHT / ATHLETIC / BREATHABLE

AIR//WEAVE™ is DAY//ONE's sport-inspired jersey fabric, built around lightweight comfort, airflow and an athletic drape.

Constructed from 100% polyester, its finely textured knit creates a breathable, tactile surface while maintaining enough body to hold the relaxed proportions of the LOCKED IN silhouette.

A moderately soft hand-feel and slight natural give allow the fabric to move comfortably with the body while retaining the structured character of a traditional sports jersey.

Selected areas feature open-mesh panel construction, introducing additional airflow, texture and visual depth while drawing from the material language of performance uniforms.

The result balances the functionality of athletic construction with the proportions and presence of contemporary streetwear.

Light on the body. Structured in form.

Sport heritage, rebuilt for everyday wear.

230 GSM · 95% Polyester / 5% Spandex
MOVEMENT / STRETCH / VENTILATION

FORM//FLEX™ is DAY//ONE's technical stretch fabric, developed for fluid movement, lightweight comfort and warm-weather wear.

Constructed from a 95% polyester and 5% spandex blend, the main fabric has a smooth, athletic-silky hand-feel with added stretch that allows it to move naturally with the body.

Compared with the more structured AIR//WEAVE™, FORM//FLEX™ has a smoother, more fluid character. The addition of spandex introduces flexibility and shape recovery while maintaining the relaxed proportions of the LOCKED IN silhouette.

The smooth main fabric is contrasted with open-hole mesh construction across selected areas, introducing greater ventilation while creating a distinctive contrast in texture and depth.

Together, the silky stretch fabric and open mesh create a lightweight, breathable construction particularly suited to warm-weather wear and movement.

Fluid in motion. Technical by construction.

The right care goes a long way. Proper washing and drying helps maintain the fabric’s texture, shape and fit, keeping your go-to pieces fresh for longer.
