A crossbody bag or belt bag is the most practical choice — it keeps your hands free, sits close to the body and is harder for pickpockets to access in a crowd. Look for something with a zip closure rather than a magnetic snap. Size-wise, you need enough room for your phone, cards, keys, lip balm and a small portable charger — most festival bags don't need to be large. Avoid tote bags or shoulder bags at crowded events — they shift around, slow you down and are easier to access without you noticing. Wristlet phone cases are a good alternative if you're travelling very light.
