If you look young, lucky you. Except when you're trying to get served at the bar.

Waterproofs and wellies
Weather forecasting is not yet an exact science.

Sun cream
Yes it's Britain, but it is going to be July and no one wants to look like a lobster or have their nose flake off.

An umbrella
Yes it's summer, but it is Britain and no one has yet come up with a roof big enough to cover the mainstage area.

A big thing
Want to get on TV? Bring a big banner, an inflatable or something ridiculous on the end of a stick. You won't regret having to carry it around with you all day. No. That's definitely not going to happen.

Cash
Queues for the ATMs have been known to reach a mile long, so try to judge how much money you'll need over the whole weekend - then double it.

Fancy dress costume
Always guaranteed to help you make new friends but Sunday afternoon at Bestival is officially fancy dress time, something that everyone takes surprisingly seriously. Don't be one of those people who look like a lemon (unless you're deliberately dressed like a lemon). This year's theme is '30,000 Freaks Under The Sea'. We're thinking new-rave octopuses.

Inflatable matress
4music never goes anywhere without ours. It's the difference between a good night's sleep in a field and a trip to the osteopath.

Condoms
There's no chance you're going to pull, looking and smelling as bad as you will, even after the first morning. But you never know when you might run out of balloons.

A little stove
Personally, we can think of better things to do than cook at a music festival. But bringing your own mini-kitchen and a supply of beans will save you a lot of money.

A stupid flag
We hope we're not being tentist when we say that all tents look the same, especially in the dark. They do. So mark yours for easy locating with a big and unmistakeable flag.

We're sure there are plenty more things you should pack in your boot, like a tent and clothes and things, but you already thought of those. Didn't you?
