Waterfly waist fanny pack – water-repellent bum bag with bottle holder, army green
If you want a straightforward, reliable bum bag that does the job with no faff, the Waterfly ONJ07 is a tidy little option. It’s cut from tough, water‑repellent nylon so a bit of drizzle or splash won’t ruin what’s inside, and the anti‑scratch finish helps it shrug off the knocks you get when clipping it to a belt or using it on muddy walks.
Practical details that matter
There are two main zip compartments plus a small outer pocket, so your phone, keys, cash, poo bags and dog treats all have a proper home. A handy key clip stops metal keys from disappearing to the bottom of the bag, and the breathable mesh back panel helps reduce sweaty backs on longer strolls or runs.
- Water‑repellent nylon fabric that sheds light rain and splash.
- Breathable back mesh pad for comfort during exercise.
- Two zipped compartments and an extra outer pocket for quick‑grab items.
- Elastic bottle holder fits a standard 650ml bottle and secures it with a strap for stability.
- Reflective strip for added visibility on early morning or evening runs.
- Adjustable waist strap from about 30cm to 117cm (12–46in) and a smooth, sturdy buckle for easy on and off.
Where it really helps
Great for dog walking, local hikes, running or everyday errands — no need to lug a rucksack when you only need the basics. The bottle holder keeps hydration close at hand so you’re not juggling a bottle while out and about. If you’re often out in low light, the reflective strip is a small but useful safety extra.
Technical specs and a few notes
Dimensions are roughly 25 x 7 x 19.8 cm and the bottle pocket is designed for a 650ml bottle. The manufacturer model number is ONJ07 and the pack is unisex. The buckle and zips are made to cope with typical outdoor use, but for heavy, prolonged rain it’s worth keeping electronics in a dry bag or using a waterproof cover.
Wondering about fit? It’s sensible to measure your waist if you’re unsure. The stated strap range will suit most people, though if you’re wearing thick winter layers the fit may feel a bit different.
Care and common questions
Wipe clean with a damp cloth and leave to air dry — avoid machine washing to preserve the water‑repellent finish. If you want to be absolutely sure your phone stays dry in a downpour, a thin waterproof sleeve is an easy precaution.
All in all, the Waterfly waist pack is a simple, no‑nonsense bit of kit that makes short trips and daily use easier. Light, handy and built for practical everyday wear.
