Best Backpacks in the UK: Trail Running, Gym Sacks and Character Mini Packs to Suit Every Adventure

Looking for the perfect backpack can feel like hunting for treasure — there are so many shapes, sizes, and buzzwords that your head can spin. Whether you’re pounding the trails, heading to the gym, or hunting for a quirky mini backpack that screams personality, the UK market has strong options. This guide pulls together top picks you’ll see at specialist stores like RunningXpert and gift-and-gadget retailer Menkind, plus other trusted UK sellers. Think of this as your treasure map: clear, practical, and pointing you straight to the bag that fits your life.

Why the right backpack makes such a big difference

Ever tried carrying a heavy load in a bag that sits awkwardly on your back? It turns even a short walk into a chore. The right pack acts like a good hiking partner — distributing weight, keeping essentials handy, and feeling invisible when you move. For runners, comfort can mean shaving seconds off your pace. For commuters, it can mean arriving at work without a sore back or damp laptop. So yes, choosing well matters.

Top trail running backpacks you’ll spot online and in stores

Trail running backpacks are a different beast from daypacks. They’re slimmer, more streamlined, and often designed to carry hydration, a wind shell, and a few essentials without bouncing. Stores like RunningXpert stock several standout models that cater to both speed and comfort.

The North Face Trail Lite Speed 20 — built for fast miles

The North Face Trail Lite Speed 20 is a classic for runners who want to cover long miles without bulk. With a capacity of about 5.3 gallons (roughly 21 quarts), it’s roomy enough for longer runs or light overnight trips. Expect clean lines, snug fit, and smart pockets so your phone and snacks are within thumb’s reach. If you’re running routes that stretch beyond 10 miles, this style gives you what you need without weighing you down.

Salomon XT 10 and Deuter Race 12 — versatility for mixed terrain

Salomon’s XT 10 (about 2.6 gallons) and Deuter Race 12 (about 3.2 gallons) are two great middle-ground choices. The Salomon leans minimalist — perfect for shorter, faster runs or days when you want to travel light. The Deuter offers slightly more room and a sturdier harness system, which feels better on longer outings or when you’re carrying a compact camera or extra layers. Both are common finds at specialist running retailers and outdoor shops across the UK.

Black Diamond Distance 8 and The North Face Sunriser Run Vest 8 — women-focused options

For those who prefer ultra-light setups, the Black Diamond Distance 8 and The North Face Sunriser Run Vest 8 (each about 2.1 gallons) are smart choices. These designs hug the body and minimize bounce, which is exactly what you want on technical trail sections. They’re hydration-ready and often feature pockets arranged to keep small items secure and accessible.

Gym sacks and everyday bags: practical, cheap and easy

Not every day needs a sophisticated harness. Sometimes you want something simple, light, and fuss-free for the gym, errands, or a quick coffee run. That’s where gymsacks and small daypacks shine.

Nike Gymsack 18l and Brasilian Gymsack — simplicity that works

Nike’s gymsacks (about 4.8 gallons) are a staple for a reason. They’re lightweight, foldable, and carry just enough for a gym kit or a quick commute. The Brasilian version adds a stylish twist with colour blocking, while the classic gym sack focuses on function. These are easy picks if you want something low-profile and affordable from mainstream brands.

Mini and character backpacks — style with personality from Menkind

If you want something fun, Menkind’s range of Loungefly mini backpacks is a go-to. These mini backpacks are perfect for fans, collectors, or anyone who wants a statement accessory rather than maximum capacity.

Loungefly character minis — from Monsters Inc. to Sanrio

Think Monsters Inc. Mike & Sulley, Minions Fluffy Unicorn, The Little Mermaid, Kung Fu Panda, Jack Skellington from Nightmare Before Christmas, Moana, Lilo & Stitch, and Sanrio’s Melody and Kuromi. These Loungefly mini backpacks are designed for style: bold graphics, quirky appliqué, and compact forms that hold essentials like a phone, wallet, and keys. They’re great for festivals, nights out, or as a talking point on the commute.

Where to shop in the UK: specialist stores and general retailers

Shopping for a backpack in the UK is easier than ever. Specialist stores like RunningXpert focus on performance packs for runners and outdoor athletes, while Menkind covers novelty and pop-culture styles. Other retailers worth checking include Decathlon UK for budget-to-midrange outdoor gear, Cotswold Outdoor and Ellis Brigham for serious hikers, Runners Need for running-specific items, Sports Direct for big-brand bargains, John Lewis for polished choices, and ASOS for fashion-forward options. Each store has a niche, so think about what matters most to you — fit, function, or flair.

Specialist running stores vs big-box and fashion retailers

Specialist running shops often provide fitting advice and demo kits that help you find the right harness and size. Big-box stores offer competitive prices and wide inventories. Fashion retailers prioritize style and trends. Which you choose depends on whether comfort on the trail, upfront savings, or looks top your list.

How to choose the right backpack for your activity

Choosing the right pack is like picking the right pair of shoes — different shapes for different jobs. Here are practical cues to help you decide quickly and confidently.

Capacity — match the pack to the mission

Capacity is the first check. For speedier trail runs you’ll often want a compact 2–5 gallon pack (that’s about 8–20 quarts). Day hikes or commute packs fall in the 5–10 gallon range. If you’re planning an overnight, step up to packs that feel comfortable carrying heavier loads. Avoid overbuying: an oversized bag encourages you to pack unnecessary weight.

Fit and comfort — it’s all about the harness

A well-fitting harness and adjustable straps are non-negotiable. Check shoulder straps, sternum straps, and belt adjustments. The pack should sit snugly on the chest and upper hips — not pulling on your shoulders. Imagine wearing the pack like a second skin: it should move with you, not against you.

Materials and weatherproofing — keep stuff dry and durable

Look for durable ripstop fabrics and water-resistant zips if you live in rainy parts of the UK. For serious wet-weather use, a pack with a built-in rain cover or treated fabric will reduce anxiety when clouds gather. Durability pays off; a pack that lasts several seasons is more economical than replacing a cheap one every year.

Storage, pockets and hydration readiness

Think about what you carry daily. Do you need a laptop sleeve, quick-access phone pocket, trekking pole attachments, or a hydration bladder? Trail running packs usually prioritize hydration compatibility and quick-access soft flasks, while daypacks lean towards organizational pockets and laptop protection.

Weight — the lightness factor

If you’re chasing speed, lightweight construction is crucial. Many running packs are intentionally minimal: think less padding, fewer buckles, and lighter fabrics. For general hiking or commuting, a slightly heavier but more padded pack can improve comfort over long hours.

Packing tips and care to keep your backpack working like new

Packing smart extends the life of your backpack and saves back pain. Put heavier items closer to your back and centrally, use compression straps to keep things tight, and avoid stuffing sharp objects that can wear through the lining. For washing, follow manufacturer guidance: many packs prefer spot cleaning with mild soap rather than a machine wash. Dry inside out and never leave damp gear locked inside; mold is the enemy of backpacks.

Budget tips: getting the best value in the UK

Want to save cash without compromising quality? Shop off-season for steep discounts, and sign up for retailer newsletters for exclusive offers. Specialist stores sometimes sell last-season models that are functionally identical to the newest release. Consider lightly used gear from reputable sources if you’re okay with second-hand — that’s often where you’ll find premium packs at friendly prices.

Matching style to use — choosing a pack you’ll actually use

Function is king, but style helps you keep using the bag. If a design makes you smile every time you sling it on, you’ll reach for it more. That’s why character minis from Menkind are so popular: they’re small, fun, and make a statement. For serious outdoor use, choose colors and reflectivity that match your visibility needs — bright colors for low-light runs and tasteful neutrals for commuting.

Final thoughts before you click “buy”

Before you commit, try the pack loaded with what you usually carry. Walk around, jog a bit if you’re buying a running pack, and ensure nothing chafes or bounces. Read reviews but treat them like tips, not rules — what’s perfect for someone else might not suit your body shape or habits. With the right approach, you’ll end up with a backpack that feels less like gear and more like a helpful companion on every outing.

In summary, the UK market serves every backpacking personality: RunningXpert and specialist stores offer performance-focused running packs like The North Face Trail Lite Speed 20, Black Diamond Distance 8, and Salomon XT 10; Menkind brings personality and pop-culture style with Loungefly mini backpacks; and general retailers supply solid everyday and budget options. Match capacity, fit, and features to your routine, and you’ll find a bag that makes life easier — and more fun.
