Waterfly Ultra Lightweight Foldable Backpack 20L

This ultra-lightweight foldable daypack offers a compact carry solution for short hikes, city days and travel when you need a simple, stowable bag that takes little space and protects essentials. With a 20-litre capacity and a design focused on easy packing and everyday versatility, it works well for commuting, sightseeing and outdoor activities while keeping weight to a minimum.

Key Points

The pack weighs just 280 g, so it hardly adds to your load when you are already carrying luggage or outdoor kit. It folds into its own pocket for neat storage and quick deployment, making it handy as a backup bag on trips. The main compartment fits an A4 book or a tablet such as an iPad, while two front pockets give fast access to small items like keys, cards and earphones. The shoulder straps are breathable mesh to improve comfort on longer walks, and the side buckle helps stabilise the load during movement. Note that the fabric is water-resistant rather than fully waterproof, according to the manufacturer.

Usage Recommendations

Carry it as a secondary pack when travelling, slipping it into checked luggage or a suitcase to use for day trips. For hiking and sports, use the side buckle and adjust the mesh straps to keep the bag steady and reduce shoulder strain. The front pocket with both zipper and hook-and-loop fastener gives flexible access to frequently used items, so place valuables there for quick reach.

Positive Aspects

The combination of low weight and packability makes this rucksack a practical choice when space is limited and lightness matters. The tear-resistant nylon increases durability for repeated use on trails or in urban settings. Its simple layout keeps organisation straightforward without excess compartments, which is useful for those who prefer minimal carry. Some users may find the 20-litre volume limiting for full-day hikes that require additional clothing or larger water supplies, so consider pairing it with a larger daypack when necessary.
