So we've compiled a useful list of festival essentials to check off as you go.
It's by no means comprehensive, but should get you started when you're staring at your backpack and trying to decide what and how to fit everything in...
Any prescribed medication you will need (for special requests / needs visit this page)
Glasses and/or contact lenses
Mobile phone (download the official IoW app here)
Tools to put up your tent
Air mattress or roll up mat
Air pillow or pillow from home
Flag or ribbon to identify your tent from a sea of identical ones
Hat, if it's sunny, to protect your head
Welly boots and/or comfy shoes
Long socks, to stop your welly boots chaffing
Enough clothes for the weekend if you get wet / dirty
A jumper or hoody for when it's getting colder at night
Change of socks - nobody wants wet feet!
Something to sleep in at night
Small bag to carry around festival, preferably zipped and across body to keep your money safe.
Watch, so you don't miss any bands
Hairbrush and/or comb
Sun cream (let's be optimistic!)
Face wipes and/or baby wipes
Tooth brush and toothpaste and/or mouthwaste
Anti-bacterial hand gel
Booze (no glass)
Food if you don't want to buy on-site
Snacks for when food stalls aren't open or you get the midnight munchies
