§ 02 — The Brief

Kneel On Wet
Ground. Stay Dry.
Stay Seen.

Standard work joggers fail the moment you kneel on wet ground — soaking through instantly. These are engineered with heavy-duty 300D waterproof Oxford knee panels that form a permanent moisture barrier. A deep-pile thermal fleece lining delivers essential warmth for 6AM winter starts, while 360° reflective banding keeps you fully visible around site machinery and vehicles.
