Product details

Waterfly bum bag fanny pack: waist pack with RFID anti-theft, army green

Looking for a neat, no-nonsense bag that keeps your essentials close without getting in the way? The Waterfly bum bag (model FP01-06) is just that — slim, lightweight and built for days when you only need the basics: phone, wallet, passport, keys and maybe a few snacks. Brilliant for travelling, daytime strolls, doing errands or nights out when pockets just won’t cut it.

Practical features

Made from 500D nylon with a PU coating, it stands up to light showers and the odd splash — not a substitute for a dry bag in a proper downpour, but perfectly fine for typical British weather surprises. Smooth two‑way SBS zips make access simple, there’s a reflective cord for better visibility after dark, and breathable mesh padding on the back keeps things comfortable when worn snug to the body.

  • Anti‑theft protection that actually helps: a lockable front zip for physical security plus a discreet rear pocket lined with RFID‑blocking fabric to help stop unauthorised electronic scans of cards and passports.
  • Adjustable and versatile to wear: the strap extends from 62 to 120 cm, so it fits a wide range of builds and can be worn around the waist, across the chest or slung over a shoulder.
  • Compact but practical capacity: about 1.5 litres (internal dimensions 23 x 13 x 5 cm) — roomy enough for modern smartphones, a slim wallet, passport and small essentials, but not for bulky kit.

Technical specifications

Dimensions: 23 x 13 x 5 cm. Capacity: 1.5 L. Weight: 170 g. Strap length: adjustable from 62–120 cm (24.4–47.2 in). Material: 500D nylon with PU coating. Hardware: SBS two‑way zips, sturdy adjustment buckle. Safety: reflective cord, lockable front zip, hidden RFID‑lined back pocket.

Who is this for?

Anyone wanting a fuss‑free way to carry the essentials without lugging a backpack. Ideal for travellers navigating busy stations, runners who want visibility, festival-goers after hands‑free freedom, dog walkers or day trippers who prefer to travel light. The long adjustable strap means it fits most body shapes.

Common questions and quick answers

  • Will it hold my phone, wallet and passport? Yes — the slim 1.5L main compartment and rear pocket are sized for those items, though very chunky wallets or large power banks might be a tight squeeze.
  • Is it waterproof? It’s splash‑resistant thanks to the PU coating, so it’ll cope with light rain, but it isn’t fully waterproof for prolonged heavy downpours.
  • Does it really stop RFID skimming? The hidden rear pocket is lined with RFID‑blocking material to reduce the risk of unauthorised scans — a handy extra layer of security when you’re travelling.

Final thought: a tidy, well thought‑out little bag that removes the faff from carrying essentials. If you want to go light, stay visible and add a bit of protection against snooping or pickpockets, this does the job — and it comes with a one‑year support promise from the manufacturer for a bit of extra peace of mind.
