What this climate and context demand

Air this dry pulls moisture straight off the skin, so sweat evaporates fast and chill sets in faster once the sun drops. Fabrics with measurable moisture regain, merino wool around 30 percent or cotton near 8, buffer that swing, holding a little damp without feeling clammy and resisting the static and brittleness bone-dry conditions cause.

Business casual sits between suiting and weekend wear, so fabrics should hold a crease without stiffness: mid-weight cotton twill, fine merino knits, and wool blends with some elastane recover from sitting and movement while keeping a clean line.

Fabric priority — Moisture regain matters most here: a fibre that absorbs and releases water buffers both the dry air's static and the wide day-to-night temperature swing.
