Rain at a festival lasts an hour. Mud lasts the rest of the weekend. That is the distinction that catches people out: the sky clears, everyone cheers, and the ground stays a churned-up mess until you go home.
Build from the ground up
Boots first. Wellingtons or waterproof lined boots, with thick socks and a spare pair. Everything else follows from having dry feet.
Then legwear. Shorts over thermal leggings beat long trousers, because trousers wick mud upwards and stay wet. If you want trousers, choose quick-dry synthetic over denim. Wet denim is heavy, cold and takes two days to dry.
Then the layer that keeps you warm when wet. Fleece and wool keep working damp; cotton hoodies do not.
Then the shell. A packable waterproof over the top, worn over the outfit rather than instead of it. This is the trick the British festival crowd learned decades ago: the nice clothes stay nice, the shell takes the beating.
What actually fails
- Umbrellas. Banned at most festivals, useless in a crowd, and the person holding one is nobody's friend.
- "Water-resistant" jackets. Resistant is not proof. Look for taped seams.
- Suede and leather. Both are finished by one wet day.
- Canvas trainers. They soak through in minutes and stay wet for the duration.
- Long dresses and wide-leg trousers. They drag through the mud and then you wear it.
The layering system that works
- Base: thermal or merino, thin, next to the skin.
- Mid: fleece or wool, warmth even when damp.
- Shell: waterproof, hooded, packable enough to live in your bag when the sun comes out.
- On top of all of it: whatever look you actually wanted to wear, adapted for the fact that you will be seen in the shell for half the weekend.
The camping problem
Mud makes camping harder in ways that are not obvious until you are in it. A few things that help:
- Bin bags, one per day, for wet clothes. Wet clothes in a tent make everything else damp.
- A boot bag at the door of the tent, so mud stays outside.
- A microfibre towel, dries fast, packs small.
- Dry socks in a sealed bag. More than you think you need.
Getting the look right anyway
Mud does not mean giving up. The best-dressed people at wet festivals follow the same two rules:
Make the practical thing the statement. A bright poncho, patterned wellies, a good shell in a strong colour. If you are going to wear it for three days, make it something you like.
Keep one dry outfit hostage. Sealed, in the tent or the car, for the last night. Everyone else is on their third damp layer, and you turn up looking human.
Which festivals this applies to
Roughly: anything on grass in the UK, Ireland, the Netherlands, Belgium, Germany or Scandinavia between May and September, and anywhere else where the guide lists a high rain risk with field or forest terrain. Glastonbury, Roskilde, Wacken, Rock am Ring, Electric Picnic and Pukkelpop have all produced legendary mud years. Their individual guides list the ground condition and rain risk so you can plan properly.
