ROSSRORE Foldable Backpack 20L Waterproof Lightweight Daypack (folds into pocket) — for hiking, travel & cycling

The essentials (and where a foldable 20L really makes sense)

If you want a light daypack that packs away neatly, the ROSSRORE Foldable Backpack is built around that idea. On paper it’s a 20L waterproof, tear-resistant backpack designed for one-day trips and everyday carrying, with the added bonus that it folds into a small pouch using the built-in zip pocket. That makes it the kind of bag you can throw into a suitcase as a spare hiking daypack, or keep in the car for short outings.

It’s also worth setting expectations: at 0.46lb it’s clearly aiming for minimalist, on-the-move convenience rather than heavy-duty, fully load-bearing backpacking. If you tend to carry heavier kit for long days, you may find this approach a bit too light (not “bad”, just not trying to be a big expedition pack).

Key features that show up in day-to-day use

Where this backpack earns its keep is the combination of foldability, organisation, and small-item access. The main zip compartment is paired with two internal pockets, plus an auxiliary zipped section. There are also mesh pockets for items you want to grab quickly.

A standout practical detail is the anti-theft zip compartment on the back panel—useful for valuables when you’re out travelling or moving around in busy areas. On top of that, it includes five trekking pole straps, which hints at a hiking-first mindset even though it’s marketed as a travel and training daypack.

And yes, the zips are bidirectional metal, which is the sort of detail that matters when you’re opening and closing the bag frequently.

Waterproof & tear-resistant build: what to expect

The bag is made from tear-resistant nylon, positioned for water resistance, abrasion resistance and scratch resistance compared with other materials. That’s the right direction for rain-splashed commutes, light showers on a walk, or general day-to-day wear.

One limitation to keep in mind: “waterproof” can mean different levels of protection depending on how it’s sealed and used in the real world. For heavy downpours or prolonged exposure, you may still want to consider an additional rain cover if your use case involves that.

Size and pack-down convenience (the bit people actually feel)

This model can be folded into a compact pouch measuring 10.24 inches x 5.9 inches x 1.60 inches using the built-in zip pocket. That’s exactly the kind of size that makes sense as a spare bag in luggage, or as an extra you don’t have to think about carrying.

For a quick micro-scenario: imagine you’re travelling and your plan includes a morning hike. Instead of hauling your main backpack, you can carry this daypack for the hike, then fold it down after and tuck it back into your suitcase for the rest of the trip.

Who it’s for (and who may want to skip it)

It suits you if you want a unisex foldable daypack for short trips—hiking, camping add-on days, cycling, gym sessions, swimming/training logistics, beach outings, jogging, shopping and general travel carry. It’s especially appealing if you like having “just in case” storage with you.

It might not be for you if you regularly carry bulky or heavy loads, or if you want a more structured touring pack where comfort and suspension become the priority. In that scenario, this is more of a lightweight utility pack than a top-tier comfort pack.

What to check before you buy

Before deciding, it’s worth thinking about how you’ll use the 20L capacity. “20L for a daypack” is often perfect for essentials, but if your daily kit expands (layers, larger camera gear, multiple big bottles), the foldable design may feel more constrained.

Also consider your expectations around weather. The material and design are aimed at resistance and practicality, but if your trips involve consistent wet conditions, you may want to plan for extra protection.

The final verdict

It’s a sensible buy if you want an ultra-light 20L daypack that folds down into its own pocket, with organised compartments and trekking pole straps for hikers who also travel. The anti-theft back zip is a nice touch for everyday use.

You may want to pass if you’re shopping for a carry system built for heavy loads or long, comfort-critical hikes. In short: it’s a convenient, travel-friendly lightweight pack, but it’s not trying to replace a fully robust backpack when you need maximum support.
