Festival season stopped being a weekend thing a while ago. If you are chasing lineups across Europe, or stringing three dates together with cheap flights and a couchsurf in between, you are not really going to a festival. You are travelling, with a festival in the middle. And the bag you pick decides how much of that trip you enjoy.
Why a Backpack Beats a Suitcase Here
Wheels are excellent on airport tile and useless everywhere else. Festival ground is grass, mud, gravel and kerbs, and a rolling case on a campsite is a comedy sketch. You also spend a surprising amount of a festival trip carrying everything at once: off a coach, across a field, through a security line, up to a hostel on the fourth floor with no lift.
A backpack keeps your hands free and your weight centred, which matters more at three in the morning than it does in the shop.
Getting the Size Right

This is where most people go wrong, in both directions. Somewhere between 35 and 45 litres covers a multi-week trip with a festival in it. Below about 30 litres you will be doing laundry constantly; above 45 and most airlines stop treating it as cabin baggage.
If you are flying budget carriers between dates, check the actual dimensions rather than the litre figure, because carriers enforce size, not volume. A soft-sided pack that squashes into a sizer will save you more money over a summer than almost any other gear decision.
What Actually Matters in the Build

A proper hip belt is the single biggest comfort upgrade, because it moves the load off your shoulders and onto your hips. Plenty of good-looking travel packs skip it, and you feel that after twenty minutes.
After that: a clamshell opening that unzips flat like a suitcase, so you are not excavating to reach a charger; lockable zip pulls, which matter in hostels; a separate compartment for wet or filthy clothes, which after a muddy weekend is not optional; and water-resistant fabric with taped zips rather than a rain cover you will lose. A well-chosen pack from a range of backpacks for men travel use covers most of that list as standard.

Packing It for a Festival Run
Packing cubes are worth the small outlay, mostly because they let you pull out one cube at a campsite rather than tipping the bag onto wet grass. Keep a small daypack folded inside for the arena itself, since most festivals will not let a full-size pack through the gate anyway.
Heavy things go close to your spine and around waist height. Earplugs, charger and a rain shell go in the top or the hip pockets, because those are the four things you will want without taking the bag off.
Buy Once
A decent travel pack costs about the same as two tickets and lasts a decade. Given that the alternative is dragging a broken suitcase wheel across a field in the dark, it is not a difficult sum.
