Review on Travel In Style: Foldable Duffel Bag 30" With 75L Capacity And Water Resistant Material by Dezz Watson

I bought this bag as a cover to protect my 75liter backpack from baggage handling equipment. This bag is ideal in the sense it weighs only 8oz and is just barely big enough for my pack and contents on an airline, where even the smallest Osprey AirPorter weighs 1lb and takes up more space when I have to carry it inside my pack. If I didn't put much in the backpack lid and cinched the straps for the lid down as tight as possible (to make the backpack as short as possible), with many of the contents like clothes put into corners outside the pack, then I could get my backpack to fit . barely.However it's not so ideal since there's no way to lock the main zipper of this duffel bag closed. There's only a single zipper pull, so you can't lock two zipper pulls together. There's no loop or ring that you can lock the single zipper pull to either.For my purposes taking buses when trekking overseas, a cheap-o fifteen dollar bag also effectively disguised the fact there was a backpack inside, and I didn't want people to guess it had really nice backpacking gear inside. So I suppose the lack of any luggage lock served to further disguise the fact there was valuable stuff inside. That's struggling to make a glitch into a feature - the OPTION to lock this bag would be better.The un-lined fabric material seems strong enough to survive multiple airline trips, it's the stitching that proved to be the weak point. Within the first five days, the main (top) zipper came off the zipper, and then that zipper pull was lost a couple days later when someone else opened the bag. I faced having to take long bus ride and then fly back home with no way to zip this bag closed. After spending 20-30 min working at it with my backpacking knife/multi-tool and a huge safety pin from my first aid kit, I managed to remove the zipper from the end pocket, get it onto the main zipper, and then put big safety pin at end of zipper run to (hopefully) keep zipper pull from going off the end again if TSA opened bag. By the time I got home the zipper pull came off again despite safety pin, however this bag served it's purpose for one trip - barely. No idea if this is a genuine Faraday bag.By the time I buy four of this disposable single-use bag for four trips, I may as well spend the same money on a ZPacks cuben fiber airline case that weighs only 3.3oz (vs 8oz for this bag) if not for the fact my big 75-liter backpack has a circumference over 41inches, so is too wide to slide inside that ultralight backpack cover.I still give this Faraday(?) duffel 3 stars only because it was still a good value at fifteen dollars and it served it's purpose for a single trip - barely!
