Waterfly 20L foldable backpack, lightweight

The essentials

Waterproof and packing-friendly days often start with the right carry option, and this Waterfly foldable backpack is built for that kind of flexibility. It offers a 20L capacity for everyday essentials on hiking trips, travel days, and sports outings, with compartments that help keep small items organised. What stands out is the balance between a light feel and practical storage, including a main section that can fit an iPad and an A4 book for commutes or day routes.

If you want a bag that does not feel bulky when you are moving around, the foldable design is a key benefit. According to the manufacturer, this rucksack weighs only 280g, and it folds down into its own pocket for storage. That means you can keep it in a larger suitcase, car boot, or travel bag without it taking up much space 🧳. When you need it, it unfolds quickly and you can use it straight away.

You also get a durable, easy-care build. The backpack uses water resistant and tear resistant nylon fabric, which is useful when the weather shifts or you are carrying items through outdoor spaces 🌦️. The fabric is described as easy to clean and anti friction, helping reduce the chance of wear during everyday handling.

Key features

The design focuses on practical access and a lightweight carry, not just general storage. The main pouch is sized for daily carry, including room for an iPad and an A4 book, so it suits school runs, travel planning, and straightforward office days. On the front, there are compartments for quick organisation, such as a pocket where you can keep keys, cards, earphones, and small personal items.

There is also a special front pocket with two opening options. One section uses a zipper, while the other opening uses magic tape, giving you a straightforward choice depending on what you are trying to grab quickly. If you prefer to separate items that you reach for often, this layout can help you keep them in reach without rummaging through the main compartment.

For comfort, the backpack includes breathable mesh shoulder straps. This is meant to help relieve your shoulders during longer walks, and it supports a more comfortable feel when the bag is on your back. A side buckle helps distribute weight and keep the backpack steady and centred, which matters when you are moving at a walking pace on trails or around town.

A useful note is that foldable packs like this are best treated as day carry bags rather than heavy load hauling. If you regularly carry very dense or bulky gear, you may want to load thoughtfully so the straps and shape can perform well.

Could it fit the kind of trips you do most often, short hikes, travel days, and gym or sports sessions? It is the sort of bag that tends to work when you want a light, organised rucksack that is easy to pack away after use.

Who it’s for

This Waterfly 20L foldable backpack makes sense if you want a compact daypack that you can pack away easily. It suits people who carry a tablet or documents, plus smaller essentials like keys, cards, and personal items, because the compartment layout is designed for quicker access. It is also a good match for active days when you want to stay comfortable on the move, thanks to the breathable shoulder straps and steady fit.

It may not be a great match if you need a very high capacity rucksack for large multi day loads. However, for day hiking, travelling, and everyday sports or outdoor use, it can be a practical option where light weight matters 🏃. You may also like it if you prefer a bag you can store neatly between uses rather than a permanently bulky backpack.
