Whether you’re commuting to the office, heading for the trails, or training for an ultra, having the right running backpack makes a big difference. And with so many options out there: vests, packs, belts, it can be hard to know where to start.

That’s where we come in. We’ve tested the latest models, chatted with our coaches, and pulled together this list of our top picks for 2025, based on what real runners actually need. Read on to find the right one for your next adventure.

What to Look for in a Running Backpack

Fit matters

A good pack should hug your torso without bouncing, rubbing, or shifting. Look for multiple adjustment points and make sure the size is right for your frame.

Hydration setup

Soft flasks vs. bladder? Bottles are great for quick sips and easy refills. Bladders hold more, but take a bit more effort to manage. Many packs support both.

Storage capacity

Choose based on your runs. If you’re out for less than two hours, a 4–6L pack (or belt) will do. If you’re racing long or running self-supported, aim for 10–20L.

Breathability and build

Ventilated mesh, sweat-wicking fabrics, and bounce-free designs all help. If you’re hitting trails or changeable weather, go for something more durable.

Bonus features

Think whistles, reflective details, phone pockets, pole loops, and extra compartments. These little details can make a big difference on race day or longer adventures.

1. Best for Run Commutes: Stolt Athlete Backpack

If your run takes you from home to the office, the Stolt Athlete Backpack is a great choice. It’s sleek, structured, and loaded with performance features like a waterproof finish, odour-resistant lining, and space for your laptop and lunch.

The 18L capacity makes it roomy enough for most workday essentials, while the adjustable straps keep things stable while you run. It’s a bit of an investment upfront, but one that pays off if you’re running to work regularly.

  • Price: £149

  • Hydration: Side bottle sleeve (1L)

  • Best for: Runners commuting with tech, kit, and daily gear

Coach Anya Culling runs to meetings in hers and if it’s good enough for her, we’re listening! Subscribers to Runna Premium also get a cheeky discount on Stolt goods, making that initial investment a little lighter.

2. Best for Steady Long Runs: Salomon Active Skin 8 Set

This one’s for those longer midweek runs or weekend efforts where you want comfort, hydration, and just enough storage. The Salomon Active Skin 8 comes with two soft flasks (500ml each), space for a 1.5L bladder, and stretch pockets that fit your phone, gels, and gloves without fuss.

The vest-style fit hugs close to your torso to stop bouncing, and breathable fabrics keep things feeling fresh even when the miles stack up.

  • Price: £90

  • Weight: 249g

  • Best for: Marathon training, long runs, or supported ultras

It’s practical, lightweight, and hits the sweet spot between minimal and capable.

3. Best for Ultras and Trail Days: Ultimate Direction Fastpack 20

Got a big mountain run coming up? Heading into the hills for a full day out? The Fastpack 20 has your back, we mean it. With up to 23L of space, it’s roomy enough for extra layers, fuel, poles, and even fastpacking kit.

What makes it work so well is the way it balances load. We love the way the vest-style harness keeps weight close to your centre of gravity, while the mesh back panel adds breathability. Whether you’re racing or just exploring, this pack’s got the space and structure to help you stay self-sufficient.

  • Price: From £120

  • Weight: 715g

  • Best for: All-day trails, ultras, or fastpacking adventures

If you’re carrying supplies for any eventuality, this is the one to trust.

4. Best Budget Option: Harrier Kinder 10L

Looking for something that won’t break the bank? The Harrier Kinder 10L delivers big performance at a smaller price. It’s hydration-bladder compatible, has soft flask pockets, and even a zipped phone compartment, all wrapped up in a comfy stretch fit.

It’s an ideal choice if you’re building towards your first long-distance race or just need a reliable trail vest that doesn’t cost a fortune. This is great pack to dip your toe into the category of running

  • Price: £59

  • Best for: Runners who want solid features at a fair price

Harrier’s known for making quality kit at runner-friendly prices, and the Kinder is no exception.

5. Best for Storage: Salomon Adv Skin 12 Set

This is the Swiss Army knife of running vests. Whether you’re tackling a mountain ultra or just like to carry a lot (we see you, Type-A planners), the Salomon Adv Skin 12 has a spot for everything: hydration, fuel, poles, layers, phone, the works.

The snug Sensifit design keeps it bounce-free, and the expandable compartments adjust depending on how much you’re carrying. It’s comfortable, fully loaded, and barely noticeable when you’re running light.

  • Price: £140

  • Weight: 293g

  • Best for: Runners who carry it all

It’s a classic for a reason and still one of the best all-rounders out there.

6. Best Reflective Pack: Proviz REFLECT360

If you’re running in the dark, visibility is non-negotiable. The Proviz REFLECT360 lights up brilliantly under headlights, helping you stay seen on busy streets or dimly lit trails.

It’s not just reflective, either. With 10L of capacity and secure waist and chest straps, it works well as a commuter or compact run pack. It’s not fully waterproof, but it’ll see you through drizzly mornings without issue.

  • Price: £49.99

  • Best for: Early starts, late runs, and urban visibility

A great shout for winter running, or anyone who trains before sunrise.

7. Best Waist Belt Alternative: Salomon Pulse Belt

Sometimes, a backpack is more than you need. For shorter runs or race day, the Salomon Pulse Belt gives you just enough storage for your phone, keys, and a gel or two — all in a super low-profile design.

Made with 4-way stretch fabric, it hugs close to the body without bouncing or riding up. You can even fit a small flask if you want to bring some hydration along.

  • Price: £32

  • Weight: 62g

  • Best for: 5Ks, park runs, or light-and-fast training

Simple, streamlined, and surprisingly roomy.

FAQ: Running Backpacks

Can I run with a backpack?

Yes! As long as it’s designed for running, that is. Regular rucksacks bounce, rub, and hold sweat. Running backpacks are snug, lightweight, and breathable—and most importantly, they’re specifically designed to be your running companion.

Hydration vest or backpack?

For short to mid-range runs, a vest or belt is ideal. If you’re carrying layers, food, or a change of clothes, a larger backpack is the way to go.

How do I pick the right size?

Match the capacity to your longest runs, and check brand sizing charts for chest circumference. A good fit is snug but comfortable; no movement, no chafing.

Are they waterproof?

Most are water-resistant, not fully waterproof. Look for roll-top designs or pack a dry bag if you’re carrying sensitive kit in wet weather.
