WATERFLY 20L Packable Hiking Daypack
A 20-liter daypack that folds into its own pocket and disappears into a suitcase, glovebox, or the bottom of a larger pack until you need it. The 20L main compartment holds a light layer, lunch, and trail basics, with side pockets for bottles and a small front pocket for keys and a phone. The shell is water-resistant and the straps are breathable mesh, so it works as a real short-hike pack rather than a grocery tote. It weighs almost nothing when empty, which makes it the bag you keep as a spare rather than your only bag.

You get to camp or a new town, decide to walk somewhere, and realize your only options are hauling the big pack or carrying everything in your arms.
🏆 How It Compares
It sits below the BECOJADDE 15L and the Osprey Daylite in structure and durability, but it is the only pack in the catalog that folds away to pocket size — the right pick as a spare, not a primary daypack.
Pros & Cons
✅ Pros
- Packs down small enough to live in a glovebox or duffel and be forgotten until needed
- 20L carries layers, snacks, and two bottles without sagging or digging into your shoulders
- Water-resistant shell and breathable mesh straps handle real trail use, not just parking lots
- Cheap enough to keep one in the car as an emergency pack for spontaneous stops
❌ Cons
- No frame or padded hip belt, so it is not a load hauler — keep it under about 15 pounds
- Thin fabric and minimal padding mean it will not survive years of heavy use like a structured daypack
- Sizing is unisex one-size, so long torsos may find the strap range limited
