What’s the one thing most men forget when packing for a UK festival?

A decent waterproof.

Not the sweaty plastic poncho you panic-buy at a merch stand.
We’re talking about proper festival fashion that works with your outfit, not against it — and keeps you dry when the rain hits.

This is your essential guide to what to wear to a festival when showers are likely (which, let’s face it, they usually are). Whether you’re after a stylish waterproof jacket, a cag in a bag, or looking for the best packable raincoats for festivals, I’ve got you covered.

Cag in a Bag? Mac in a Sac? What Are They?
Call them what you like — cagoule, packable raincoat, jacket in a packet, mac in a sac, coat in a tote — they all do the same job: fold away small, whip out fast, keep you dry, and don’t ruin your festival outfit.

These aren’t camping-shop horrors either. The latest styles are slick, minimal, breathable, and made for modern men who want to stay sharp, not soaked.

Should I Take a Waterproof to a Festival?
Short answer: yes.
Even if it’s forecast to be sunny, you’d be mad not to bring one.

Here’s why:
• Most UK festivals involve open fields and unpredictable weather
• You won’t want to carry a brolly
• A stylish waterproof jacket is the easiest way to save your outfit

Showerproof vs Waterproof: What’s the Difference?
This is where a lot of people get caught out.
• Showerproof = water-resistant, not water-tight. Good for a light drizzle or short dash.
• Waterproof = fully sealed, designed to handle heavy rain and long exposure.

If you’re going to be dancing in fields for hours, choose a fully waterproof coat.

• H&M Rain Macs often deliver good styling at low prices. Just double-check they’re actually waterproof.

How to Style a Waterproof at a Festival?
Here’s how to wear a waterproof coat without ruining your festival look:
• Go for neutral colours: Black, olive, grey or tan always work
• Size up: Gives you that relaxed, oversized, festival vibe
• Layer smart: Throw over a hoodie or oversized tee
• Match your footwear: Think waterproof trainers, boots, or wellies
• Pack light: Make sure your jacket folds down — it should clip to your belt or fit in your backpack

Short-Term Fix or Long-Term Style Investment?
If you’re doing one small day festival, a budget could work but may not keep you dry.

But if you hit multiple events or like your outdoor wardrobe to be sharp, invest in a proper waterproof.

You’ll wear it again — from city commutes to countryside walks.
