What to Pack for O Days Festival 2026

For O Days Festival 2026, pack light and pack smart: ID, a charged powerbank, a light rain layer, sunscreen, comfortable shoes, and a small bag. O Days runs 30 July to 1 August 2026 at Refshaleøen in Copenhagen, and it is an 18+ city festival with no camping, so you are packing for long days and late nights, not a weekend under canvas.

The trick at a harbour-side festival is bringing what you need for the day without hauling it all on your back. Stash the rest in an Event Locker and move freely.

The O Days essentials

Start with the things that stop the day going sideways.

• Valid ID. O Days is 18+, and you need ID for entry and to swap your ticket for a wristband. No ID, no entry.
• A charged powerbank. Your phone is your ticket, your camera, your map, and how you find your friends. It will not last a full day and night alone.
• Card and a little cash. Most bars and stalls take card, but a bit of cash is a useful backup.
• Comfortable shoes. Refshaleøen is old shipyard ground. You will be on your feet from afternoon to 1 am.

Dress for Copenhagen in late summer

Late July and early August in Copenhagen can serve up warm sun and a sudden harbour shower in the same afternoon. Pack for both.

• A light waterproof or windbreaker you can tie around your waist.
• Sunglasses, a hat, and sunscreen for the open, shade-light site.
• A warmer layer for the evening, when the wind comes off the water and the temperature drops.
• Ear protection if you like being close to the speakers, and reusable ones fit in a pocket.

Keep your bag small

Festivals move faster when bags are small, and a compact bag gets you through the entrance quicker. Check the official O Days website for the current bag rules and the list of items you cannot bring, since those are set by the festival and can change year to year.

The smart play is to carry only what you need on you and lock the rest away. An Event Locker at O Days holds your spare layer, charger, sunscreen, and valuables, and you open it from your phone whenever you want something. That way you are not the person carrying a heavy backpack through a crowd all night.

What to keep on you

• Phone and a charged powerbank.
• ID, card, and a bit of cash.
• Sunglasses and sunscreen for the afternoon.
• Your rain or evening layer, or leave it in the locker until you need it.

What to leave in a locker

• Spare clothes and a change of top for the evening.
• The powerbank and cable when you are not charging.
• Anything valuable you do not want in an open pocket in a crowd.

Remember there is no power outlet inside the locker, so charge your powerbank the night before and bring it full.

O Days packing FAQ

Do I need to bring cash?

Mostly no. Card works at most bars and stalls, but a small amount of cash is a handy backup for anything card-only.

Can I bring a big backpack?

Keep it small. A compact bag speeds up entry, and the festival sets the bag rules, so check the official O Days site before you go. If you want to bring more, book an Event Locker and stash it there.

What about rain?

Bring a light waterproof. Copenhagen summers flip between sun and showers, and a jacket you can tie around your waist covers you either way.

Is there anywhere to store my stuff?

Yes. Volt runs Event Lockers at O Days, in all-days and single-day options, so you can lock away what you do not need on you and open it from your phone through the day.

Pack it, then plan the rest

Once your bag is sorted, tie up the other two:

• Book your Event Locker at O Days so the day bag lives on the island, not on your shoulders.
• Sort getting to O Days so the trip to Refshaleøen is the easy part.
• See the O Days festival page for everything Volt runs on site.

Light bag, charged phone, right layers. That is a festival you actually enjoy.
