Waterfly waist bum bag — water-repellent bottle-holder, navy blue
Practical, straightforward and well thought-out — this Waterfly waist pack is perfect for anyone who’d rather not faff about with a bulky rucksack. It keeps your essentials tidy and within easy reach, while staying comfortable, breathable and secure. The navy finish looks smart for day-to-day use but won’t shy away from a walk in the park or a muddy trail.
what it is and why it helps
This compact bum bag has two zip compartments, an outer pouch and a dedicated bottle holder that keeps a 650ml bottle snug thanks to an elastic strap. The main fabric is water-repellent nylon, so light showers and splashes won’t ruin what’s inside. A breathable mesh backpad helps cut down on sweat and rubbing when you’re walking, jogging or out with the dog — a proper bonus in the warmer months.

size and practical notes
Dimensions: approximately 25 x 7 x 19.8 cm. Adjustable waist strap fits roughly 30 cm to 117 cm (12″ to 46″). The bottle holder will take most 600–650 ml bottles; very wide bottles or insulated flasks may be a snug fit. The pack suits phones, keys, cash, small cameras and other essentials — if you’ve got a particularly large smartphone, it’s worth measuring first against the pack dimensions.
Care is simple: wipe clean with a damp cloth and leave to air dry. If you’re planning to use it for very heavy loads or in extreme weather, check that it meets your needs — this pack is designed for convenience and everyday outdoor use rather than heavy-duty mountaineering.
All in all, a no-nonsense, comfortable and versatile little pack that keeps the things you need close at hand. No more rummaging, no bulky kit — just a tidy, practical solution for getting outside.
