What to wear to Dekmantel Festival: Amsterdam sits at 22°C (72°F) by day and 14°C (57°F) at night in August, on forest, with a moderate chance of rain. That means a light base with one warm layer you can carry, broken-in boots or sturdy trainers, and a bag small enough for the gate rules. The crowd leans techno, underground and forest, so black and functional reads as insider.

Function reads as style: technical shells, utility pockets and proper footwear are no longer the compromise choice. Here that plays out mostly in the layer you carry rather than the one you start in.
