This is a generic foldable duffel bag from an unbranded Amazon seller. At under £25, expectations should be calibrated accordingly. I bought one as a backup gym bag and have used it for six months.
What You Get
A medium-sized duffel (48 x 28 x 28 cm) made from thin polyester fabric. It folds flat for storage, has a separate shoe compartment, a trolley sleeve to slip over suitcase handles, and several external pockets.
This is the type of bag you see selling under dozens of different brand names on Amazon – essentially the same product repackaged. The quality is consistent across sellers: budget materials, functional design, and acceptable performance for light use.
Features
Foldable design: The bag compresses and folds into a compact packet. Useful if you want a backup bag that doesn’t take up much space when not in use.
Trolley sleeve: A strap on the back slips over your suitcase handle. Works as advertised – convenient at airports.
Shoe compartment: A separate vented pocket on one end holds shoes away from your clothes. The ventilation is minimal (small mesh panel) but it keeps dirty trainers isolated.
Multiple pockets: Front zip pocket, internal slip pockets, and a “wet pocket” (basically a lined pocket for damp items). Organisation is adequate for a gym bag.

Pros
- Cheap – Under £25 for a functional bag
- Folds flat – Good as a backup or secondary bag
- Trolley sleeve – Genuinely useful feature
- Shoe compartment – Keeps dirty shoes separate
- Lightweight – Easy to throw in a suitcase as a spare
Cons
- Thin material – Won’t survive rough handling long-term
- Basic zips – Functional but not smooth
- No structure – Flops without contents, looks messy
- Unbranded – Quality varies between batches
- Limited durability – Fine for occasional use, not daily abuse
Is “Waterproof” Accurate?
The listing claims water resistance. The fabric has a coating that repels light splashes, but this isn’t a waterproof bag. Heavy rain will seep through, and the zips aren’t sealed. Fine for walking from car to gym in drizzle – not suitable for genuine wet conditions.
Who Should Buy It
This bag works for:
- Occasional gym-goers who need something cheap and functional
- Travellers wanting a foldable backup bag to pack in luggage
- Anyone needing a secondary bag for shopping, beach trips, or storage
- Budget buyers who’d rather spend £20 now and replace later than £60 on quality
It’s not suitable for:
- Daily use – The materials won’t last under constant wear
- Heavy loads – The straps and fabric aren’t designed for weight
- Rough treatment – This won’t survive being thrown around by baggage handlers
- Quality seekers – If you want something that’ll last years, spend more
Compared to Alternatives
vs UA Undeniable 5.0: The UA costs about double but has significantly better materials, water resistance, and durability. Worth the upgrade for regular gym use.
vs Decathlon duffels: Similar price, similar quality. Decathlon bags often have marginally better zips and stitching.
vs Other Amazon generics: Near-identical. Pick based on reviews, colour preference, or whoever has stock.
Verdict
This is exactly what it appears to be: a cheap bag that does the job for light, occasional use. The foldable design and trolley sleeve are genuinely useful features. The shoe compartment works. The build quality is adequate but not durable.
If you need a backup bag, a secondary gym bag, or something you won’t cry about if it gets damaged, it’s decent value. If you want something that’ll last through regular use, spend more on a name brand.
