Waterfly Ultra Lightweight Foldable Backpack 20L

This ultra-lightpack daypack from Waterfly combines low weight with a surprising 20 litre carrying capacity, useful for day trips, commuting and travel. Foldable into a small pouch, it tucks into luggage or a larger bag so you have extra storage when needed, and it reduces shoulder strain during short hikes thanks to breathable mesh straps.

Key Points

The pack weighs around 300 g, making it one of the lightest options to carry for extended periods. It is made from ripstop nylon that resists tearing and helps keep contents dry in light rain, according to the manufacturer. A removable front pocket adds a playful, customisable element and can be exchanged with other pockets of the same model to change colour or organisation. The design includes side compression straps to stabilise the load and prevent items shifting while you walk.

Usage Recommendations

Use this pack as a compact spare for day hikes, urban exploring or as a gym carrier. When folded into its tiny pouch it occupies minimal space in luggage, making it handy for travel. For outdoor trips with heavier loads consider using the compression straps and distributing weight toward the middle to keep the pack centred and comfortable.

Positive Aspects

Ventilated shoulder straps help reduce sweat build-up and shoulder fatigue on warm days. The ripstop fabric offers improved abrasion resistance over standard nylon and minor moisture protection in light showers. The removable front pocket is practical for separating small items such as a map, snacks or a lightweight rain jacket, and it allows personalisation if you collect different colour variants.

Note that the pack is best suited to light to moderate loads and may not offer the support needed for heavy or prolonged backpacking trips. The water resistance is limited to the fabric and does not replace a waterproof cover in heavy rain.
