The hardest part of shopping for backpacks daypacks is deciding how much pack you actually need. A 20-liter pack can disappear into your luggage, and a 50-liter pack can carry a week's worth of gear - but they serve very different adventures. The decision comes down to what you're carrying and whether you want a bag that folds flat or one that's ready for heavier trail days.
Quick verdict
Choose the 20L Ultra Hiking-Daypack if you want a packable, lightweight day backpack for lighter loads and a lower listed price. Choose the Adjustable 50L Hiking Daypack with Rain Cover if you need more room, a larger capacity, and an included rain cover.
At a glance
| Product | Listed price | Capacity / key feature | Price bar |
|---|---|---|---|
| 20L Ultra Hiking-Daypack Lightweight Foldable Travel Packable Backpack | USD 14.65 | 20L, folds to about 8.6 x 3.1 x 1.06 inches | |
| Adjustable 50L Hiking Daypack with Rain Cover | USD 89.99 | 50L, adjustable daypack, rain cover included |
How to decide
Packability matters when this bag will ride inside another suitcase or be carried only part of the time. The 20L Ultra Hiking-Daypack folds down to a listed size of 8.6 x 3.1 x 1.06 inches, so it can be tucked away when empty. A 50L daypack is a bigger commitment in volume, but it can take on longer day trips that demand extra layers, food, or gear. The 50L pack also includes a rain cover, which gives you a layer of protection against heavy rain and dust without needing a separate cover.
Where each product wins
- 20L Ultra Hiking-Daypack Lightweight Foldable Travel Packable Backpack wins for packability, portability, and a lower listed price. It is suited to day trips, cycling, and stashing in larger luggage.
- Adjustable 50L Hiking Daypack with Rain Cover wins for capacity and weather protection. It offers a 50L load and a rain cover for heavier outdoor excursions.

This pack is the lower-priced choice in this head-to-head. It weighs 2.3 ounces, folds down to a compact storage size of 8.6 x 3.1 x 1.06 inches, and has a water-repellent coating on the surface. For day hikes, cycling, or as a spare bag inside bigger luggage, that packability is the main draw. The trade-off is capacity: it offers 20L of space, which is enough for a light load, but won't match the 50L pack for longer trips or bulky gear. If you want a bag that rarely takes up space when empty, this is the one to consider.
Adjustable 50L Hiking Daypack with Rain Cover - Perfect for Outdoor Adventures

The 50L pack has a listed capacity of 50 liters, making it the roomier option. It comes with a rain cover, and the features include tear-resistant polyester and nylon fabric, breathable mesh shoulder straps, and a no-internal-frame design. It is the higher-priced pack here, so you're paying more for a larger load plus the included rain cover. The trade-off is that a 50L daypack is a bigger bag for half-day trips or urban use; you may not need all that space when you're running errands or going on a short walk. If your trips include longer distances, larger gear, or weatherproofing, this pack gives you that room from the start.
Final choice by use case
- Quick trail outing, travel backup, or compact carry: the 20L Ultra Hiking-Daypack keeps things light and packable.
- Longer day hikes, heavier loads, or rain protection: the Adjustable 50L Hiking Daypack with Rain Cover offers extra capacity and an included rain cover.
