Juggling your phone, wallet and keys while on the move can be a real hassle. A bulky backpack isn't always practical for a quick trip to the shops, a festival or a morning run. The modern bum bag, also known as a crossbody bag or sling bag, offers a hands-free solution that combines convenience with contemporary style.
As the Joybuy Product Recommendation Officer, my role is to help you navigate the options. This guide cuts through the clutter, focusing on practical features to help you find a bag that genuinely suits your lifestyle, whether you're commuting across the city, travelling abroad or simply need your essentials within easy reach.
Before diving into specific products, let's consider a few key features that separate a great bag from a mediocre one.
The British weather is nothing if not unpredictable. A water-resistant bag is a practical choice for protecting your electronics and other valuables from sudden downpours. Look for materials like high-tenacity nylon or treated polyester, which offer a good balance of durability and low weight. This is especially important for a travel bum bag or festival bag that will be exposed to the elements and frequent use.
Consider what you need to carry daily. A compact bag is ideal for just a phone and keys, but what if you need space for a power bank, sunglasses or snacks? Some models offer expandable compartments, providing flexibility. Internal pockets are also crucial for keeping items organised and secure, preventing keys from scratching your phone screen. A well-designed small shoulder bag with smart dividers can often be more practical than a larger, single-pouch waist pack.
The modern bum bag is rarely worn just around the waist. Look for models with long, adjustable straps that allow you to wear them as a crossbody bag slung over your chest or as a sling bag on your back. This versatility not only enhances comfort but also allows you to adapt the bag to your outfit and activity. For those with an active lifestyle, a dedicated running belt might offer a more secure, bounce-free fit.
Here are a few standout options that cater to different needs, from daily use to specialised activities.
Why It Stands Out: The Beneunder LC169’s most notable feature is its clever twin expansion system. It starts as a compact 1.2-litre pouch, perfect for minimal essentials, but can expand to a generous 3.6-litre capacity when you need to carry more. It’s also incredibly light, weighing just 98 grams, so you’ll barely notice it's there.
The high-tenacity nylon fabric is another highlight, offering resistance to water, oil and stains, making it a durable companion for urban life.
Pros:
Who is it for? This bag is well-suited for city dwellers, commuters and travellers who value versatility. Its ability to adapt from a minimal pouch to a larger carrier makes it ideal for unpredictable days.
Why It Stands Out: Coming from a brand known for performance gear, the Under Armour Essential Waist Bag is built to last. It’s constructed from a 160 GSM water-resistant polyester fabric that feels both lightweight and robust. Its design DNA is sporty yet understated, making it a seamless addition to casual or athletic outfits.
The versatility is a key selling point; it functions equally well as a traditional waist pack for a workout or as a stylish crossbody sling for daily errands.
Pros:
Who is it for? This is a great choice for fitness enthusiasts, weekend adventurers and anyone who appreciates a sporty aesthetic. If you need a reliable, no-fuss bag for the gym, a walk or running errands, this fits the bill.
Why It Stands Out: This waist pack is purpose-built for one thing: hands-free hydration. It integrates a soft, squeezable water bottle directly into its design, making it a specialised running belt. The zippered pocket provides just enough space for essentials like a key, card or energy gel.
Safety is also considered, with reflective accents that enhance visibility during early morning or evening runs. The bottle itself is made from taste-free, phthalate-free HDPE plastic.
Pros:
Who is it for? This is specifically for runners, walkers and hikers. If your primary need is to carry water and a few small items during exercise, this specialised waist pack is an excellent tool for the job.
If these recommendations aren't quite what you had in mind or if you'd like to see a broader selection of wearable bags, there are many other designs to consider.

The main difference is how they are worn. A traditional bum bag is a small pouch worn on a belt around the waist. A sling bag typically has a longer strap and is designed to be worn across the chest or back (crossbody). Many modern designs are convertible, functioning as both a waist pack and a sling bag thanks to adjustable straps.
Absolutely. The bum bag has seen a major resurgence but has evolved in style. Today, it's more commonly worn as a crossbody or sling bag and is seen as a practical and fashionable accessory. It has become a staple at festivals, in cities and for travel, prized for its convenience and minimalist appeal.
For most water-resistant fabrics like nylon or polyester, it's best to spot clean. Use a damp cloth with a small amount of mild detergent to gently wipe away any dirt or stains. Avoid machine washing, bleaching or using high heat, as these can damage the protective coating and the bag's structure. Always let the bag air dry completely before using it again.
