3.0 out of 5 stars Lightweight, but Flimsy and Very Basic

2026-01-14    -Michigander

I’m honestly not very impressed with this COSCOOA travel backpack. Yes, it’s lightweight, just like they say, but that’s because it’s made of a thin nylon fabric. It doesn’t really hold its shape at all unless it’s fully packed, which makes it feel a bit flimsy to me.The size is small, so I can see how it would fit under an airline seat without an issue. Layout-wise, it’s pretty basic: small side pockets on each side, one large front half pocket, and one main large compartment. No structure, no padding, nothing special.It’s usable if you just need a very simple, lightweight personal item bag, but overall it feels cheap and underwhelming. Not terrible, just not something I’d be excited about or buy again.

It weighs nothing in your luggage but becomes a full-size bag when you need it. I use it for extra shopping, unexpected souvenirs, or as a daypack during tours. The self-storing pouch is genius—just stuff it in and go. Incredibly handy!

2.0 out of 5 stars Disappointing. Way too flimsy for travel use. Not durable. Photos are deceptive

I was really hoping this backpack would be a handy travel bag, but it ended up being extremely underwhelming and disappointing. The material is way too thin and it feels like it could tear easily along the seams and zippers. I would definitely not put anything heavy inside it. The zippers are also poor quality.The biggest disappointment was how the bag looks and feels nothing like the photos and the description in the Amazon listing. In the photos, the bag looks solid, firm and boxy, but in reality, there is no firmness at all to it and you will not be able to rest it flat because the bottom is way too thin and has no structure to it at all - (the entire bag, including the straps, is too thin and flimsy). It will just flop over and there is no way it can stand firmly upright on a carry-on bag or any flat surface.In the product description, it’s even described as “anti-theft design”. I don’t understand this one? I guess that only works if a thief yanks hard on it, the bag might tear apart and all your items will scatter onto the ground. Anti-theft…maybe in the sense that no thief can steal the backpack in one piece.But in all seriousness, I would not trust this backpack for anything important like a passport, wallet, or electronics. The thin and flimsy material makes it impractical to carry flat on your carry-on. Honestly, it feels more like a cheap novelty than a serious travel bag. Not worth the price at all. Buyer beware.

5.0 out of 5 stars From Pocket to Backpack in Seconds

The magic of this bag is how tiny it packs down. It literally fits in my jacket pocket, yet unfolds into a sturdy, comfortable backpack. Perfect for hiking, festivals, or beach days when you want a hands-free bag but don't want to carry it all day beforehand. The material is surprisingly durable. Love it!
