SKYSPER Lightweight Travel Backpack Anti-Theft RFID Foldable Daysack (20L)
Product description
The essentials
If you’re the sort of person who wants one bag that’s easy to pack away, then gets used once you’re actually out and about, this SKYSPER 20L foldable daysack is built around that idea. It’s described as lightweight and packable for travel and day trips, and it also leans into theft concerns with an RFID-blocking layer plus a hidden zip pocket.
On paper, it ticks a few practical boxes: it folds down to a small carry size for luggage, opens up to a 20L layout for everyday bits, and uses a 210D nylon build intended for day-to-day wear. It’s not a big expedition pack, though—this is more about convenience and organised carry for normal outings.
If you’re comparing it to bulkier daypacks, the trade-off is clear: you’re buying portability and quick packing over maximum capacity or heavy-duty trail performance.
You may want to ask yourself: do you need anti-theft features for your typical plans, or would a simpler pack be enough?
Key features that matter in real life

Packable, travel-first design
The backpack is positioned as lightweight for travel and day trips, and it folds down compactly so it can fit into a suitcase or luggage. That’s genuinely useful when you’re going away with a main bag and want a secondary day option without adding much extra weight.
A good micro-scenario: you arrive at your destination, stash the folded daysack inside your larger case, then pull it out for a walking day. With a 20L capacity, it’s the kind of size for a change of clothes, a layer, snacks, and your essentials—without turning into a carry-all that feels cumbersome.
Anti-theft RFID plus hidden storage


Where this bag tries to be more than “just another daypack” is security. The listing mentions RFID blocking to help protect credit cards from copying, and a hidden back zippered pocket aimed at shielding passports, wallets, and phones from scanning theft.
It’s worth keeping expectations realistic: RFID blocking can reduce certain risks, but it won’t replace common-sense habits like keeping valuables with you and not leaving the bag unattended.

Organised carry with multiple pockets
You get three zippered compartments, plus additional pocket space: a main compartment for clothes, a kangaroo-style pocket suggested for snacks, and two side pockets for a water bottle. There’s also a mention of secure storage for maps and valuables.
This kind of pocket layout tends to suit people who hate “everything mixed together” bags—think documents in one place, day essentials in another, and snacks instantly reachable.

What you’ll notice day to day

The overall feel you should expect from a foldable, lightweight bag like this is practicality over stiffness. The listing specifically notes soft mesh shoulder straps meant to keep you cool and comfortable, which matters on longer walks or warm days when you’re carrying it for hours.
The design is described as minimalist, but with “smart storage”, meaning you’re not only relying on one big compartment. For commuting to work, popping to a shop, or going on a short hike, that organisation can make the difference between “it works” and “why is everything hard to find?”.


Who it’s for (and who should skip it)
Worth considering if
It makes sense if you want a compact travel backpack you can pack into luggage, and you like having separate zip sections for valuables and everyday items. The RFID and hidden-pocket approach is a sensible extra layer if your trip includes busy places such as cruises, amusement park visits, or international travel where you might be handling documents.
It’s also a good fit if you typically do day trips, light hiking, work outings, shopping, or cycling/fitness style errands and don’t need a large load.

It might not suit you if
You may want to skip it if you’re expecting a high-capacity backpack for multi-day trekking, heavy loads, or rough off-trail use. With a 20L size and a packable, lightweight construction, it feels more like a dependable day companion than a serious endurance pack.
It may not be a great match if you don’t care about RFID blocking and hidden storage—because then you could choose a simpler pack without paying for features you won’t use.
Buying verdict
This SKYSPER 20L foldable anti-theft RFID daysack is a pragmatic choice if you need one bag that packs away easily, opens out into a neatly organised 20L daypack, and includes a security-focused hidden pocket plus RFID blocking for cards. The 210D nylon build and soft mesh straps suggest it’s aimed at everyday travel and light use rather than heavy-duty adventures.
Buy it when your plan looks like: “main luggage for travel, plus a smaller day pack once you’re there”, and you want separate storage for documents and valuables.



Avoid it when you’re after maximum space, top-tier technical hiking support, or you’re carrying heavy gear. In that case, it could feel undersized and its foldable, lightweight approach may be less reassuring for demanding loads.
