1. TENT - Yes, you'll need one of these, they come in many shapes and sizes and degrees of putting-up-difficulty. Failing that you may be able to make some kind of deal to share somebody else's tent!
2. SLEEPING BAG - It fits nicely into a tent as you fit snuggly into it's shiny, sheath-like surround. Buy one with a zip or buy two and zip them together!
3. WELLIES - Or a big, hard pair of boots. Avoid trench-foot, stay dry-toed, and perhaps snap up some really funky festival ones.
4. TOILET ROLL - Do not assume toilets will be regularly restocked, as most don't even stock in the first place. Take lots and keep it on you.
5. TICKETS and WALLET/PURSE - If you forget to bring this, then you may as well forget all the above, unless you own a camper van and fancy ram-raiding your way in.
6. RUCKSACK - They are handy for carrrying all your stuff to the festival and if you are like me, everybody elses stuff too.
7. PANTS and SOCKS - These have a habit of getting wet, smelly, lost, or stuffed down toilets fairly regularly, so stock up unless you are comfortable wearing none.
8. SUNCREAM - Listen to Rage Against The Machine's 'Bomb Track' before you go ('Burn, burn, yes you're gonna burn') should remind you to slap it on.
9. TROUSERS - Just one spare pair is necessary for emergencies, but you'll probably spend the entire weekend in the same ones and not care.
10. TORCH - It gets dark out in the middle of nowhere - and you probably get drunk. Very useful for navigating your way tentwards without tripping over guy ropes.
11. WET WIPES - Great for keeping clean, waking you up in the morning, and generally keeping disease from spreading all over your face or other parts.
12. JUMPER - One mammoth fleecy xxxxx of a body warmer, plus a few lighter numbers. You'll fluctuate in warmth throughout the weekend so good to have various layer combinations.
13. MOBILE PHONE - It may work on site, it may not, but good to have all the same. Stay in contact with your friends or find them again when you lose them all and make new ones by collecting numbers from nice people.
14. TOILETRIES - Keep your breath, armpits, and other bodily parts fresh and clean with a range of products, including toothpaste, deodrant and soap.
15. HAT - Conquer dodgy wake-up hair by covering it with a hat. Experiment with degress of wackiness, practicality, and style. I always buy a new festival hat every year!! Or try dabbling in a wig.
16. SUNGLASSES - Ensure you can still see by the end of the weekend by wearing shades to protect from harmful rays. Remove intermitently to avoid panda eye, which one of my friends didn't do last year and they are still being slagged off for it!
