Running vest or running belt — which suits you?

Fjorn — Running vest or running belt? Same goal, more options
Guide — Gear 9 min read

If you've just started running you've probably already run into the question: should you buy a running belt or a running vest?

I've run with both, and for me it actually started with the belt. It felt simpler, less technical and above all less like a statement. For a long time a running vest felt like something for people who ran marathons, ultras, or were training for their next big race.

But after a while I noticed the belt wasn't always enough.

On longer runs especially, it became clear how much easier things are when you can bring fluid, fuel and an extra layer. These days I'd rather use a running vest when I need to carry more — but I still think a belt can be the better option for certain sessions.

So which should you actually choose?

The running belt — simple and unobtrusive

A running belt is probably the simplest way to start carrying things while you run.

It fits a phone, keys, a card and sometimes a few gels or other fuel. That's particularly practical if you run shorter routes and don't really need much with you.

For a short 3–5 kilometre run you might not need multiple pockets, water bottles or room for an extra top. A running belt can be exactly what you need.

It's also less fabric around the body, and can feel cooler on warm summer days.

But there's a drawback I noticed fairly quickly: the space is limited.

Once you start adding a water bottle, more fuel or an extra layer, it gets hard to fit everything. A running belt also tends to bounce more as you run, particularly with a bit of weight in it.

That can make a real difference when the pace picks up.

The running vest — more room, nothing in your hands

What I like most about the running vest is how close to the body it sits.

Instead of one larger pocket around your waist, you can spread what you need across several pockets and compartments. The phone has its place, fuel another, the flasks another still.

That doesn't just mean you can carry more — it also makes things easier to reach while running.

If you've ever run with one big pocket you'll know the feeling of digging around for a gel or your keys. With several separate pockets you can instead keep things where you know they are.

The other big advantage is stability.

When the vest sits properly against the body it moves with you instead of bouncing around the way a belt can. You notice it especially when you run faster or do intervals.

When is the belt actually better?

Even though I prefer a vest for most sessions, I don't think the running belt is bad.

There are situations where I'd pick a belt instead.

01

Shorter runs

If you know you won't need water, a phone and keys is usually all it takes.

02

Plenty of aid stations

In races where you can top up along the way, carrying fluid is weight you don't need.

03

Warm summer days

Less fabric around the body can feel cooler in the heat.

A full water bottle does weigh something. Even if a good vest sits stable, it's unnecessary extra weight if you know you'll be able to drink along the route.

And on genuinely hot summer days a running vest can also feel warmer than a belt.

Which is why I don't think the question is really "running vest or running belt — which is best?"

The better question is: what are you going to do on this run?

When is the vest the better choice?

For me the difference becomes clearest when the session gets longer.

When I started running without any kind of carrying gear, the furthest I could go was around 15 kilometres before thirst and hunger became a major factor. I often felt that was exactly what stopped me pushing further.

Once I started using a running vest I could bring water and fuel and top up during the run instead. I noticed a real difference in my endurance fairly quickly.

That doesn't mean a running vest automatically makes you a better runner. But being able to drink and take on fuel during a long session can make it easier to keep going when your body starts asking for it.

01

Longer distances

Fluid and fuel to top up with become decisive the longer you're out.

02

Intervals

A vest that stays put gives you nothing to think about as the pace rises.

03

Nordic weather

Room for an extra layer when the clouds turn, mid-session.

04

Darkness & visibility

Reflective detailing keeps you visible, whatever the distance.

01 — A vest for intervals, not just long runs

One thing I think is easy to miss is that a running vest isn't only useful over long distances. It can be genuinely practical during interval sessions too.

When the pace goes up, the last thing you want is something jumping around and hitting you. Depending on the model and how much is in it, a running belt can move more as you accelerate and slow down. A vest that sits tight against the body keeps things more in place.

You can also spread gels, phone, keys and everything else across several pockets. That means you can get what you need without rummaging through one big compartment. It's a small detail, but over the course of a session it adds up.

02 — Nordic weather is another reason to choose a vest

For those of us running in the Nordics there's one more reason to appreciate a running vest: the weather can't always be trusted.

In spring and autumn you can start a session in cloudy but dry conditions at a temperature that feels perfectly fine. An hour later the situation can be entirely different.

I've been out on runs where you start in a single top and after ten kilometres wish you'd brought a rain or wind jacket.

That's when it's very welcome to have a spare jacket packed in the vest. Instead of cutting the route short when the rain starts, you just pull the jacket out and carry on.

The same goes for when the temperature drops. A thin extra top or another layer can be the difference between ending the session early and actually finishing it. It's one of the things that makes a running vest especially relevant for Nordic conditions.

03 — Reflectivity and visibility when you run in the dark

The Nordic climate isn't only about cold and rain. For parts of the year it also means many of us run in darkness.

Early mornings, evening runs after work and sessions through the darker months all make visibility considerably more important. A running vest with reflective detailing can be a good complement to your other reflective gear.

If you run near roads or in areas with traffic, you want to make it as easy as possible for drivers and others to spot you. Reflective detailing across a larger part of the body can also be an advantage compared to a small reflective element around the waist.

It's still important to use proper reflective gear and adapt to your surroundings, of course, but the vest can be part of the whole.

But aren't running vests just for serious runners?

No. That's actually one of the things I think is most wrong about how running vests are sometimes presented.

When I started running, a vest felt more like a statement than a belt did. I think a lot of beginners feel the same. But there's really no reason for it.

You don't have to run a marathon to get something out of a running vest.

Even if you're only running three kilometres it can be good to have somewhere to put your phone and keys. Particularly since a lot of running kit doesn't have especially useful pockets.

And if you run a bit further, being able to bring water and fuel can make it easier to reach your training goals. Being able to drink or take on fuel without stopping is sometimes exactly what lets you keep going a little longer.

A running vest isn't a sign that you're trying to be more serious than anyone else. It's simply a tool.

Fjorn Light #01

This is roughly the kind of use we had in mind when we developed Fjorn Light. The idea isn't that you should have to be an elite runner or race ultras to get something out of a running vest.

Fjorn Light is built to let you bring what you actually need on a run, without the vest feeling heavy or bulky. It has several separate pockets and compartments for water bottles, gels, keys, phone and an extra layer — so you can organise your things instead of putting everything in the same pocket.

The vest also carries a reflective print to help you stay visible in darker conditions. And although you can bring considerably more than with a simple running belt, the vest doesn't have to feel heavy — Fjorn Light weighs roughly the same as a running belt.

So — vest or belt?

If I were to sum it up:

Running beltSomething simple for shorter sessions, where you mainly need room for a phone, keys and maybe a little fuel.
Running vestYou run longer, want to bring water and fuel, need an extra layer, or want better stability as the pace rises.

And if you're unsure, you don't actually have to choose once and for all. I use both, depending on the session.

But if I could only pick one option to cover the widest range of runs, I'd take the vest.

Not because it's more advanced. Not because it makes you look more serious. Simply because it gives you more options.

Your running gear should help you run — not get in the way of it.
