Waterfly bumbag waist pack – complete black
After something simple, reliable and fuss-free for a run or a weekend stroll? The Waterfly ONJ12 bumbag does exactly what it says on the tin — keeps your essentials close and organised without faffing about. It’s the sort of kit you sling on, forget about and only notice when you need it.
Practical features
Three zipped compartments stop everything rattling into a tumble. Two larger pockets will take most phones, a powerbank and a small wallet, while an internal zipped pocket keeps cash or receipts tucked away. Four card slots prevent cards from rubbing together, and a keychain clip means you won’t be scrabbling around for your keys.
Comfort and fit
The belt adjusts from 40–125cm and comes with a 30cm extender, so it fits a wide range of shapes — from slim waists to those a bit more generous. The back panel is padded with breathable mesh, so it sits comfortably and helps cut down on sweat on warmer days. An anti-slip fixing buckle tidies away excess strap and stops the bag sliding when you’re on the move.
Built to handle outdoor use
Made from lightweight nylon with a water-repellent finish, it’ll shrug off light showers and perspiration but isn’t intended for submersion. Robust SBS zippers reduce snags and breakages, and the buckle is built to last even in colder weather. There’s also a headphone jack for listening to music while you’re out and about.
Where it works best
- Everyday running and jogging when pockets are a nuisance.
- Day hikes and short walks where you only need the essentials.
- Dog walking, cycling, or trips to markets and festivals where hands-free storage helps.
- Travel and sightseeing when organised, secure storage matters most.
What does it actually solve? No more rummaging for cards, dropping keys down the back of pockets, or feeling weighed down by a bulky rucksack on short trips. It isn’t a substitute for a full backpack, but for daily exercise and quick days out it makes life noticeably neater. One thing to flag — it’s water-repellent, not fully waterproof, so avoid heavy downpours or dunking it if you need proper protection.
