Product description
If you’re the kind of person who likes to travel light, this Waterfly Ultra Lightweight Foldable Backpack makes a lot of sense on paper. It’s designed to fold away for easy carrying, then unfold when you actually need a proper daypack. That “packable” idea is the whole point here, and it shows in the weight and storage-first design.
That said, it’s not the sort of backpack you buy expecting expedition-level structure. A 20L foldable rucksack will always be more about convenience and everyday practicality than maximum rigidity. If you want something tough for frequent heavy loads, it’s worth thinking through your use case before you commit.
Key points
This model is a lightweight, foldable 20L daypack aimed at the in-between moments: commuting to a walk, a day out on holiday, a camping stop where you want an extra bag, or even grabbing supplies while shopping. It’s made to be easy to stow away in a small space when you don’t need it.
For day-to-day comfort, it includes mesh, breathable shoulder straps, and there are side buckles intended to help keep the bag stable and the weight better distributed. Storage is practical rather than fancy: a main compartment with inner organisation, three front pockets, and two side pockets.
One of the more playful details is the removable front pocket insert. It comes off via the zip and Velcro, and the idea is that you can swap and mix it with other front pockets from the same model (and potentially different colours). It’s a small feature, but it can change how quickly you reach for smaller items.
What stands out
The headline feature is the foldable, ultra-light approach. The bag weighs only 300 g (as stated) and can be folded into a small pack for carrying around. If you often end up needing “one more bag” while out, this is the kind of item that earns its place.
The build also focuses on everyday wear and tear. It’s made from ripstop nylon fabric, positioned to resist tearing, moisture, and scuffs. There’s reinforcement in multiple places, plus SBS zips. It’s not a promise that nothing will ever get damaged, but it is designed to handle typical bumps, knocks, and wet-weather surprises better than a very flimsy foldable.
Capacity is clearly communicated at 20L. In real use, that tends to fit the sort of kit most people carry for a day: a light jacket, water bottle, a few layers, snacks, small toiletries, and some spare space for whatever you pick up along the way.

Getting the most from it
For hiking, travelling or camping, this kind of foldable daypack tends to work best when you pack with the “light and organised” mindset. Use the main compartment and internal organisation for items you don’t need instantly, then reserve the front pockets (and the removable front pocket insert) for small essentials like cards, a phone, keys, or quick-grab accessories.
A practical example: imagine you’re on a day trip. You keep the bag folded in your bigger case or under your seat. Once you arrive, you unfold it, put a water bottle into a side pocket, pack a thin rain layer and a snack into the main compartment, then use the front pocket for sunglasses and chargers. When you head back, it folds away again.
The side buckles are worth using properly. They’re meant to distribute weight and help keep the bag stable and centred. If you stuff it loosely or overload it, any lightweight bag can feel a bit unstable, so it’s best to pack evenly.
Where it may fall short
The main limitation is inherent to the product type. A foldable 20L backpack that weighs just 300 g can’t be expected to match the feel of more structured daypacks when the load is heavy or awkward. If you’re planning to carry substantial weight for long distances, you may find it sits less “confidently” than a backpack designed with thicker frame support.
Also, the removable front pocket insert sounds flexible, but it depends on what’s available for swapping within the same model range. If you don’t plan to buy additional front pocket options, you’ll still get the benefit of the included removable section, but the “mix and match” idea may not fully matter to you.
Who it’s for (and who should skip it)
It makes sense if you want a packable rucksack you can carry without thinking about it, then deploy for everyday activities like walking, travel days, camping trips, and quick shopping outings. The mesh straps and intended weight distribution are a bonus for comfort when the load is moderate.
It may not suit you if your priority is maximum support for heavier loads, or if you need a very rigid frame feel. It’s also better avoided if you’re expecting technical hiking ergonomics designed around long, demanding treks.
Final verdict
Worth considering if you like the convenience of an ultra-light, foldable 20L daypack and you mainly carry moderate essentials. The ripstop nylon, SBS zips, reinforced stitching, breathable straps, and organised pocket layout are all aligned with “grab it, unfold it, go”.
Don’t buy it expecting a heavy-duty touring backpack. If your plans involve carrying large weight or you’re very sensitive to how structured a bag feels, this one may feel more like a practical secondary daypack than a primary workhorse.
