Pacsafe Citysafe CX 後揹包，超完整開箱評測！ (A Complete Review of Pacsafe's Citysafe CX Backpacks)
- Of course the one thing that I like about this bag and why I always choose this as my go-to travel bag is the anti-theft features there every zipper has an anti-theft feature like this pull tab right here when it goes through the loop um you can't just easily unzip it I mean you have to kind of tuck it in and then unzip it which you know it's not so easy to do if you're not someone who's familiar with the bag and you're trying to pickpocket someone like an instance it's really not doable with these bags also the top part as well it's a little bit more complicated on how to undo the anti-theft an anti-lock feature where this is like the rhubarb system but it kind of locks into place clips into place at the top the two tabs and then you stick it inside this loop which is like a second layer of security so yeah it's a it's really nice that it has this feature because it really does make it difficult for pickpocketers to you know easily get into your bag so the main thing about me when I travel is I want to have a bag that has a luggage sleeve so I don't have to carry it on my back all the time especially when I'm going to the airport or I don't really need where I have my suitcase with me so this has that feature right here and it fits and it fits on all my suitcases um it glides on or slips on really easily and then if I wanted to carry my bag like this I can easily carry it like this also if I want to put this down somewhere which I don't really do this that often but I guess it's a feature they put on there because there are people that do this like if you're sitting at a cafe or a restaurant and or you're just somewhere sitting down there's nowhere to place your bag but on the ground if you just put it down and you're not really paying attention to it someone could just walk by and snatch your bag so what these bags have is you can undo the strap on the bottom and then loop it around something that you know like a the leg of a chair or a table and then clip it back into place so when this is attached to something obviously it's harder for someone to just snatch your bag also what I like about this bag when I'm traveling is it has two side pockets and I use these pockets all the time I like to keep a water bottle or some you know one of my drinks on this side and on the other side for miscellaneous items for like an umbrella like a small umbrella the top also is like a bucket style so when you open it you're really able to open this bag and see clearly inside everything without much trouble and there is a laptop sleeve again a feature I need when I'm traveling because I do carry my laptop with me when I'm traveling and this fits a large my 15 inch laptop so actually let me grab it real quick so yeah the laptop slides in just fine I love that there's a padded sleeve in there and this also eliminates the need for me to have another like bag to protect the laptop I can just carry my laptop like this so yeah this is it's another feature that this is another reason why I carry this bag with me when I'm traveling there are other little pockets in here which I don't use the RFID pocket here a zipper and in here I usually put my valuables like my passport or extra credit cards because it's basically you know a pickpocketers can't or not even I guess you don't want to call them pickpocketers but these can't scan your information off the cards or your passport when it's in this protective sleeve so the front pocket is nice and big as has different compartments I just throw in a bunch of stuff in here any little miscellaneous items I like to stick in here I like that pack safe makes bags that are more stylish for women I when I'm wearing something nice and not so sporty I like to have a bag that matches that and yeah it's not I don't really like when I'm wearing something less sporty and then having a super sporty bag it's not something I think matches and I want to match so I do like that pack safe makes bags that are more feminine when I travel with this bag I put my laptop my camera my valuables and also one day's worth of clothing and it fits all of that and then my my drinks on the side so this this bag handles a lot so this is why it's my go-to bag when I am traveling okay next is the city safe cx backpack mini and this is an 11l and it's pretty much the same anti-theft features as the other bag actually let me hold it side by side so um just do this like a size comparison it is smaller much smaller than the 17l so this is 17l this is 11l there's a big there's a big size difference this bag like I said it has the same anti-theft features has the rubar lock here has the pull tab here it has the strap here that you can unhook and then you wrap around something and also it has the rfid safe zipper inside so um yeah so all the anti-theft features are the same some of the other features that are similar is it has a front pocket and also has the laptop sleeve now this one fits a I believe what was it I think it fits a 13 inch laptop let me just double check on that all right so yeah this one fits a 13 inch laptop so my other laptop won't fit in this one but that's fine because I don't really use this bag for traveling I use this bag more for stuff like where I'm in the area where I'm traveling so like say if I want to go to the aquarium or go to the museum that's when I would use this bag over the other bag top part too is the same how it's like a bucket style when you and it opens like really wide and then also there's handles like this so you can carry it like this as well if you're looking for a bag like to do things around town or sightseeing this is a great size bag so next to the packsafe city safe cx petite backpack isn't this so cute but for size comparison so here is the mini and this one is the petite I like the color this one this is a cute bag it's also a little bit more of a rounded shape whereas this one's a little bit more boxy like the other one so like here's the three bags like these two look more similar than this one let's see how this one's a little bit more round it's because it doesn't have that bucket style zipper opening it does have the you know very similar anti-theft features it has the the ru bar here also the same feature where you can undo the strap and wrap it around something and there is a pocket in the back where you can access your items and it does have that anti-theft feature there the pull tab so you can grab things from there so the mini bag doesn't have the side pockets but this one does which is great it does have two side pockets and it's a it has a pocket but I don't think you can I mean I guess you can fit a small drink in there it might be a little bit hard because there's not much room but on the other side it's a little bit different because there is actually a button here and there's like a little bit of a there's like elasticity here so it actually expands so you can put and I have like stuck my tumbler here and if it if it's just fine there is a front pocket but it's it's hidden with from this cover on top so if I flip it up so you can see that there is a hidden zipper there so what's different about this one I think I mentioned it earlier the other two like when you open it's kind of like a bucket style so it has more of like a square opening this one's more rounded so it it opens up more like a normal backpack and it does have the RFID safe zipper pocket here and it has a cup it has a couple of sleeves and then it does have an iPad sleeve so you can fit up to I believe an 11 inch iPad or tablet I would say there's enough room to maybe have like some miscellaneous items a small camera just like little things I would say like this bag I use more for like running around town like little errands or if I go to a cafe you know nearby it's not a bag that I travel with when I'm like going on a flight because it's a little bit too small for to fit all the things I want to bring on bring with me I love this color I also like this feature right here because this makes it easy to hang it up when I'm not using it instead of just putting it on the floor if there is a hook you know I can hang it up so I like that it has that feature this petite bag is adorable I love the anti-theft features yeah and I like the the one in the back here too it's like it's like I feel like this one is more it has more hidden zippers than the other ones because I forgot that there was like a pocket in the front and then this one in the back where the other two bags don't have the um the zipper in the back and the last bag is the CitySafe CX convertible backpack and this is the 8.5L to 5L and the reason why there's two measurements is because once I convert this into a crossbody bag it's then a 5L what I like about this bag is that it's a two-in-one so if you're someone that wants to travel light or if you're a minimalist this is a great bag for you so right now it is in the backpack style and of course it has like a lot of the same anti-theft features it has the pull tab down here there is a front pocket here and also has a little sleeve in there this one does not have the uh side pockets for you know like a drink or something it also does not have the trolley sleeve which makes sense because when it's a bag this small I don't think it's really necessary to you know put it on a suitcase so in back here there's also a zipper there's like a little zipper back here and then there is a RFID safe zipper pocket inside and you can also fit a 11 inch tablet or ipad because there is a a sleeve in here for that if you want to protect it but the greatest feature about this bag is that it's convertible say I don't want to use it as a backpack I want to use it as a purse so all I have to do is um oh yeah I forgot to mention also has the the feature where you can um undo the straps and you know wrap it around something so anyway so I just undo the straps and remove both sides of it and then all I do is then hook it on a different d-ring on the sides that they have here and then I just fold this down and there is a magnet inside you can't see but that's what's holding it down so now it's a cute crossbody purse so now I can wear it like this and you can still grab stuff from here it's got the pockets the RFID pocket and then if I want that's more easily accessible if I want to grab things from here you can do it like this way as well I think the other way is easier though to just grab things from this side but um you have two ways of opening the bag oh yeah for size comparison so this is the petite and this is the convertible I want to say like they're very similar in size yeah like if you're not if you're not someone that needs a convertible backpack I would say go with this one because I do like I like the design a little bit more of this one it's a little bit more sleek I like having things a little bit more hidden and it has the side pockets um whereas this one doesn't have the side pockets but you know if you do want a bag that's convertible um yeah definitely go with obviously because you can't convert this bag I love the color too such a cute color this pink color so those are the four bags there is one more bag from the city safe cx line I'll show it to you but it's not really a bag that I use that often again because I like bigger bags because I carry camera equipment if you're someone that doesn't need a backpack doesn't carry a whole lot of things with you just you know your small essentials you just want to cross body this is a great bag it's you know it's a cross body bag it's got the strap here it's adjustable it's got the same features it's got the um anti-theft feature here if you want to loop it around a table or a chair and the zipper here it does uh it clips on the top the tabs and then it does have that rhubarb system here there is an RFID safe pocket and there is also a padded sleeve here I guess the padded sleeve obviously you can't fit a tablet or anything but for your phone if your phone doesn't have a case and you want a little bit more extra protection there's a like you know there's a padded sleeve in there all right so that's my review of the pack safe city safe cx backpacks they're all anti-theft bags they are my favorite for traveling I do like that these bags a little bit more feminine and not so sporty I hope I covered everything it's kind of I feel like I'm forgetting something because there's so many bags at once but if you have any questions just let me know comment below and I'll try to answer the best I can if you like this video please give it a thumbs up and don't forget to subscribe to our channel thanks for watching bye
當然，我最喜歡這款包的一點，也是我一直選擇它作為旅行包的原因，就是它的防盜功能。我的意思是，你必須先把拉鍊塞進去，然後再拉開拉鍊，如果你不是一個熟悉包包的人，而你又想扒竊別人的話，這就不太容易做到了。防盜鎖功能就像大黃系統一樣，它可以鎖住頂部的兩個卡扣，然後把它塞進這個環裡，這就像第二層安全保護，所以它有這個功能真的很好，因為它真的可以讓扒手很難輕易進入你的包。這樣我就不用一直揹著它了，尤其是在去機場的時候，或者我不需要帶著行李箱的時候，所以這個包就有這個功能，它適合我所有的行李箱，嗯，它可以很容易地滑動
- and there's a little bit of elasticity here, so it actually expands.
