Waterfly Bumbag waist fanny pack – Dark Grey, adjustable belt

Waterfly bumbag waist fanny pack – Dark Grey

Modern, practical and utterly unfussy — this Waterfly bumbag is for folks who want sensible storage without any faff. The slimline design sits comfortably at the waist, across the chest or on the back and keeps your essentials neat while you crack on with a walk, run or commute. It’s made for everyday outdoor use rather than diving in a river, so expect good weather resistance rather than scuba-level waterproofing.

what fits inside

The bag has three separate zip compartments plus an inner zipped pouch for valuables. Two main compartments will happily hold most phones, a powerbank and a compact wallet, while the front pocket is perfect for tissues, dog poo bags or a few snacks. There are four card slots to stop cards rubbing together, and an internal keychain clip so your keys won’t disappear to the back of the bag.

features you’ll actually use

• The belt adjusts from 40–125 cm and a 30 cm extender is included — so it fits a wide range of sizes and can be worn a few different ways.
• Breathable mesh padding on the back keeps you more comfortable on warmer days and during longer efforts.
• High-quality SBS zippers and an anti-slip fixing buckle that tucks away excess webbing and stops the pack shimmying about.
• Water-repellent nylon outer sheds light rain and sweat, protecting your gear on quick showers or sweaty runs.
• Lightweight at around 181 g and compact (23 x 4 x 12 cm), so it won’t feel bulky while you’re out and about.

typical use and why it helps

Ideal for running, hiking, cycling, dog walking, festivals or everyday travel. Need your phone and keys handy for a quick loop? This bag makes them easy to reach. Heading out for a longer hike and want a neat way to carry a powerbank, map and snacks? Two main compartments keep things organised so there’s no rummaging mid-route. No complicated setups — just clip it on and off you go.

If you’re wondering about heavy rain: it’s water-repellent and will cope with showers, but for prolonged wet weather a dry bag or waterproof cover is a safer bet. The small internal zipped pouch is handy for cards or cash, which is a proper bonus in busy towns or on public transport.
