Waterfly Bum Bag Fanny Pack (Peacock Blue) – 1.5L RFID anti-theft crossbody/waist bag
Product description
A bag that fits your day (and doesn’t get in the way)
A slim bum bag sounds like one of those “nice to have” accessories—until you actually want your hands free. The Waterfly Bum Bag Fanny Pack is designed for exactly that: keep essentials close, wear it crossbody or around the waist, and move through travel days, commuting, walks or runs without juggling a tote.
On paper, it hits a sensible middle ground: a compact 1.5L capacity with a light 170g weight, so it’s not trying to replace a proper backpack. It’s also built around everyday practicality—smooth-feeling zips, an adjustable belt for different carry styles, and security features that aim to reduce both physical and digital worries.
What stands out in use
The most noticeable day-to-day feature is the carrying flexibility. The bag is sized to sit neatly at the waist or be worn as a shoulder or crossbody option, depending on what feels comfortable that day. If you’re heading out for a city commute or a quick errand run, you can keep it low on the body and access the front without rummaging.
There’s also a thoughtful safety touch: reflective strips that flash when hit by vehicle headlights. That’s aimed at low-light visibility, such as night runs, cycling or darker commutes. It won’t turn you into a safety beacon in all conditions, but it does add a layer that more basic waist packs sometimes skip.
A small note that may matter to some people: the bag is slim by design, so it’s best suited to smaller “on-the-go” items. If your idea of a day bag includes more bulky gear, you may find the capacity restrictive.
Storage and capacity: what it’s realistically for
With a slim 1.5L capacity, this fanny pack is built for essentials: things like a mobile phone, wallet, passport and similar daily carry items. The dimensions given (23cm x 13cm x 5cm) reinforce the idea that it’s an organiser for the basics, not a storage box for everything.
The rear pocket is lined with RFID-blocking material, which is intended to help protect cards/passport details from unauthorised digital scanning. Alongside that, the front zipper is lockable for physical security.
So if you often travel with documents and cards in a pocket, this is the kind of bag you buy to reduce friction: no awkward bag management, fewer opportunities for pickpocket-style distractions, and a bit of peace of mind when you’re on the move.
Materials and build: durability where it counts
This waist pack uses 500D nylon with a PU-coated surface. That combination is presented as abrasion- and tear-resistant, which is what you want for frequent wear—especially if the bag brushes against seats, luggage handles, or outdoor surfaces during hikes and walks.
The zippers are described as SBS, and the design focuses on smooth pulls. In reality, that’s the kind of detail you appreciate most after a few trips—when you’re pulling open the bag repeatedly and you don’t want it to feel snaggy.

Who it suits, and who should look elsewhere
It’s a good fit if you want a compact travel and everyday hip bag that keeps essentials secure, with the bonus of RFID-blocking and a lockable zipper. You’ll probably like it if you cycle or do evening walks and you’re after that extra visibility detail. It also suits buyers who prefer switching wear styles—waist for hikes, crossbody for busy days, or a shoulder position for events.
You may want to skip it if you’re trying to carry a lot more than phone, wallet and travel documents. Because it’s intentionally slim, it’s more “grab-and-go” than “full day kit”. Also, if your main requirement is maximum storage space or heavy technical outdoor carry, this looks more like a practical everyday pack than an all-terrain organiser.
Is it worth it?
Buying the Waterfly Bum Bag Fanny Pack makes sense when you want lightweight, hands-free access to your essentials, plus dual anti-theft features (lockable front zipper and RFID-blocking rear pocket) for travel and commuting. It’s also reasonably well thought through for low-light use thanks to reflective strips.
It may not be the best choice if you need a larger bag for bulkier items or if you expect it to replace a backpack on longer days. For day trips, running errands, walking the dog, and travel-on-the-move, though, it reads as a tidy, security-minded everyday solution.
