Waterfly large bum bag fanny pack – dark blue waist pack for hiking
What this pack is good for
Here’s a tidy little solution for days when pockets just won’t cut it. The Waterfly large bum bag, in a smart dark blue, keeps your essentials close without any faff. Perfect for a run, a day hike, a festival or popping down the shop — it’s simple, secure and comfortable to wear.
Practical design that actually works
There are five zippered compartments of varying sizes so everything has a proper place — phone, cards, keys, snacks and even a small water bottle. The largest compartment has a roomy inner divider and will take a standard 500ml bottle. Two inner slip pockets in the second compartment are ideal for a mobile and cards, while the front pockets give quick access to the bits you use most. No more rummaging about when you’re on the move.
Comfort and durability
Made from water-resistant nylon, the outer fabric helps protect contents from drizzle and splashes — it’s not a waterproof dry bag, but it’ll shrug off light rain and sweat. The back panel has a breathable mesh pad to cut down on sweating and ease pressure on the hips, so wearing it for hours is surprisingly comfy. Strong SBS zippers and a robust buckle mean it’s built to last.
