Waterfly Bum Bag 1.5L RFID waist pack
Product description
A compact, hands free waist pack can make a big difference when you are out for the day, especially if you want quick access to essentials and extra protection. The Waterfly bum bag fanny pack brings a slim 1.5L capacity for travel, commuting, and everyday errands, while keeping the fit flexible thanks to an adjustable belt. It also uses dual anti theft features with RFID blocking and a lockable front zipper, which is useful when you are moving through busy areas or catching transport. 🧳
If you carry a phone, wallet, keys, and a couple of travel documents, this type of bag is designed to stay out of your way while you walk, run, or cycle. The grey design suits both men and women, and the reflective strips can help visibility in low light when vehicle headlights hit them. ✨

Key features


Waterfly’s approach here is practical and straightforward, combining a slim silhouette with everyday carry capacity. The main body is made from premium 500D nylon with a PU coated surface, which is described as abrasion and tear resistant for regular use. For movement, the bag uses SBS zippers, designed to make opening and closing feel smooth even when you are on the move.

There is also a smart elasticated drawstring design, so you can secure the bag quickly and keep the contents stable during travel or outdoor activities. When you want to grab something fast, the front storage and zipper access are built for quick reach rather than rummaging. 🏃
A standout part of the design is the dual anti theft protection. The front zipper is lockable for physical security, and there is a hidden rear pocket lined with advanced RFID blocking material. That combination is intended to help protect your phone, cards, passport, and cash from both pickpockets and unauthorised digital scans.



What to know
Sizing and adjustability matter with bum bags, and this one is designed to suit different carry styles. The waist pack measures 9in x 5.1in x 1.97in, which is 23cm x 13cm x 5cm, and the adjustable strap ranges from 24.4in to 47.2in, or 62cm to 120cm. In practice, that means you can wear it as a waist belt bag, as a shoulder bag, or as a crossbody bag for city commuting.

The slim build is supported by a lightweight feel, with the bag weighing 170g as stated by the manufacturer. It is described as spacious enough for everyday essentials like a mobile phone, wallet, passport, and more, which helps if you want to travel light without sacrificing the basics. If you often go out without too many items, having hands free storage can reduce the hassle of juggling bags while you walk.


One more useful detail is visibility in low light. Reflective strips are described as flashing brightly when hit by vehicle headlights, which can be helpful for night runs, cycling, or urban commutes. Tenors can vary, so it is worth remembering that reflective elements rely on external light to be most visible.

Who it’s for
It’s a good fit if you want a slim waist pack that stays comfortable while you move, whether that is for travel days, walking in the city, or outdoor activities. You’ll like it if you prefer to keep essentials close and hands free, and if you value added security with a lockable front zipper plus RFID blocking. It also suits day trips and active routines such as running, cycling, gym sessions, hiking, and dog walking, because the bag is described as lightweight and adaptable.
Not the best choice if you need a large storage setup for heavy gear, since the capacity is kept deliberately slim. It might not suit you if you prefer a fully structured, rigid bag shape rather than the elasticated drawstring approach. If you want a compact 1.5L carry option with adjustable crossbody comfort and anti theft features, Waterfly Bum Bag is worth considering for your everyday kit.
