What to wear to Time Warp: Mannheim sits at 15°C (59°F) by day and 6°C (43°F) at night in April, on industrial site, with a moderate chance of rain. That means thermal layers under a statement outer layer, cushioned trainers or a low boot, and a bag small enough for the gate rules. The crowd leans techno, warehouse and underground, so black and functional reads as insider.
