Product details

Lightweight bum bag for travel, hiking and everyday use

Need a tidy, no-nonsense way to carry the essentials when you’re out and about? This Mayoii bum bag does exactly that — light, neat and up for a bit of drizzle. It’s ideal for dashing from the station to the trail or when you’d rather avoid the faff of a bulky rucksack.

smart, simple design

The bag has two zip compartments plus a hidden pocket for anything you’d rather keep under the radar — phone, wallet, keys or that stray boarding pass. Pockets are roomy enough for everyday kit but compact enough to stop things bouncing around. The adjustable strap lets you wear it around the waist or sling it across the chest for a more contemporary look.

who is this for?

Perfect for hikers, commuters, festival-goers, runners or anyone who likes to go hands-free. If the thought of rummaging through a big bag while balancing a coffee makes you wince, this is a far better option. It sits close to the body so it won’t swing about when you’re walking briskly or jogging — a proper plus on the move.

key features and advantages

  • Lightweight build — sits at under 100g, so you barely notice it on longer walks.
  • Water-resistant fabric — will shrug off light rain and spills.
  • Two main zip pockets plus a hidden pocket for safer storage.
  • Adjustable waist belt for a comfy fit — wear it low, high or cross-body.
  • Ergonomic cut and breathable backing reduce bounce and keep things comfortable.

technical details and practical notes

Package dimensions are approximately 27.8 x 15.4 x 5.2 cm and the bag weighs around 100 g. Made in China and supplied by Mayoii, the model is listed simply as ‘bum bag’. The fabric is water-resistant rather than fully waterproof, so for heavy downpours or submersion you’d want a dry bag, but for everyday showers and sweat it does the job well.

Will it take a large smartphone? In most cases, yes — though if you’re carrying an oversized phone with a chunky case it’s worth checking the pocket dimensions first. The strap adjusts to fit most shapes, but a specific waist range isn’t provided here, so try before you buy if you need an exact fit.

All told, this is a practical, stylish and fuss-free waist pack that ticks the boxes for travel, sport and everyday life. No faff, easy to use and dead handy when a full backpack would be overkill.
