What to wear to Igloofest: Montreal sits at -8°C (18°F) by day and -16°C (3°F) at night in January, on snow, with a moderate chance of rain. That means thermal layers under a statement outer layer, insulated waterproof snow boots, and a bag small enough for the gate rules. The crowd leans snow, techno and apres-ski, so black and functional reads as insider.

Below freezing, the outfit is a system: base layer, insulating mid-layer, windproof shell. Style happens in the outer layer and the accessories. Everything else is thermal engineering.
Everything below follows from those numbers.
