What to wear to Mad Cool: Madrid sits at 34°C (93°F) by day and 20°C (68°F) at night in July, on city streets, with a low chance of rain. That means loose natural fabrics and real sun protection, cushioned trainers or a low boot, and a bag small enough for the gate rules. The crowd leans indie, rock and streetwear, so anything that survives the day reads as right.
