Product details

Mayoii lightweight bum bag — travel, sport and hiking (green, one size)

Handy, compact and no fuss — this bum bag is for anyone who wants to carry the essentials without lugging a bulky rucksack. It hugs close to the body, leaves your hands free and tucks out of the way when you don’t want it. Ideal for a morning run, a day on the trail, a festival or just popping into town.

Practical features

  • Two main zippered compartments for your phone, wallet, snacks and a small camera — keeps things tidy so you’re not rummaging when you shouldn’t be.
  • Hidden rear pocket for cards or keys that need a bit of extra security while you’re on the move.
  • Water-resistant outer fabric to guard against light rain and sweat during active use.
  • Adjustable waist strap that’s comfortable whether you wear it around your hips or sling it across your chest for a more urban look.
  • Breathable backing and an ergonomic shape to cut down on bounce when you’re jogging or hiking at pace.

Technical details

Constructed from a durable, water-resistant fabric with smooth zips and a solid buckle. The manufacturer lists the packaged weight at around 130 g, while the style is marketed as ultra-lightweight — under 100 g — so expect a very light feel compared with most day packs. Compact dimensions but roomy enough for a smartphone, a small wallet, keys and a few bits and bobs. Country of origin: China. Manufacturer: Mayoii.

Who is this for?

  • Runners and hikers who want their essentials close to hand without the bulk.
  • Travellers and commuters who need secure pockets and quick access.
  • Festival-goers and shoppers who prefer hands-free convenience.

Care and tips

Wipe clean with a damp cloth and air dry. Avoid prolonged exposure to heavy rain — water-resistant means it’ll shrug off splashes and light showers, not full submersion. If you’re unsure about fit, fiddle with the strap and try both waist and cross-body positions — it often feels steadier across the chest for faster activity.

You might spot slightly different weight figures in listings; that’s usually down to packaging or small production variations. Either way, it’s still a very lightweight, no-nonsense bum bag that keeps your essentials safe and makes life a bit easier on the move.
