I couldn't resist jumping on the belt bag craze to try this bag. Before I discuss why I like this bag, let me first explain why I hate belt bags. 1) They are ugly. 2) It's more awkward to retrieve items from a belt bag then it is to retrieve them from a handbag. 3) They rarely fit what I consider to be my daily essentials (phone, wallet, prescription sunglasses and keys), and when they do fit all of the above items, they are usually bulky, and 4) aren't we all just sick and tired of seeing the ubitiquitous and overpriced LLL brand colonizing public life everywhere? It's like watching the Stepford Wives, which Wikipedia describes as a 1972 feminist horror film about how something in the town of Stepford was changing all the wives from free-thinking, intelligent women into compliant wives dedicated solely to homemaking. While the LLL bag isn't changing women into compliant housewives, there is something scary about it that I can't place my finger on.HOWEVER....I have flown twice in the past month -- once for pleasure and once for a funeral -- and I have concluded that air travel is so unpleasant that it is worth it to me to strip down all of my travel items to the bare minimum. Yes, I prowl the website of Her Packing List to read with amazement how she traveled for 3 weeks with a 12 liter bag. Plus, I work the polls on election day and I wouldn't mind having the teeniest, tiniest bag that will hold my phone and keys from 6 a.m. until 10 p.m.So, I was already primed to think about how I could further minimize my daily handbag, which is already pretty small, for travel, when I arrived for the above-mentioned funeral, and saw another guest wearing this bag. The first thing I noticed is that it did not have the ubitiquous LLL logo. Not seeing any apparent logo, I asked who made the bag and where she got it.Upon arriving home with my new resolve to minimize minimize minimize my travel (did I mention the sprint at 10 p.m. in the Atlanta airport from Terminal B to Terminal E to catch a connecting flight, with my already small handbag flapping against my thigh with every trot??) I immediately ordered both the single zipper bag and the double zipper bag. Having explored them both thoroughly, I'm going to keep the double zipper bag, and now I'm going to tell you what I like about the bag:1) Overall, the bag feels really well made. The material of both the bag and the strap feels nice and quiet to the hand. There are no loose threads. The zippers work, although one of the zippers needs a little extra help getting around the curve, but not enough to bother me.2) While both the single zipper and double zipper bags have a "hidden" zippered compartment that faces the body, on the double zipper bag, it is slightly larger, and you can slip a passport in and out with ease. While you can fit a passport in this compartment in the single zipper bag, you have to work a little more to make it fit.3) I have tried other belt bags where if you bent over without closing the bag, all of the contents of the bag fell out. "Huh?" you might be asking. "Why would a person need to bend over without zipping their bag?" Well, let's say I'm walking the dog and also scanning my phone for interesting text messages, and now the dog has pooped and I want to put the phone in the bag while I scoop the poop. Cotopaxi comes to mind as a bag where all contents fell out in this scenario. Now you may be saying that a person who walks her dog and checks for text messages at the same time is as terrible as a person who wears a LLL belt bag. And I don't disagree with you. But there could be other, more benign scenarios where you may want to leave your bag unzipped and not want to dump out all of its contents. Here's one: Pretend you are sitting on a plane and your meager food has arrived, and to make room on your meager tray, you put your phone in your bag, but you don't feel the need to zipper it, knowing you are going to return to it as soon as your meal has finished. But as you finish your meal and return the tray to its upright position, you drop something important. Your earplugs, perhaps. The cookies that you were saving to provide a moment of joy on an otherwise torturous, cramped flight. As you contort yourself to bend over, and having forgotten that your bag is unzipped, you catastropically dump your phone AND your chapstick into the unreachable bowels of the plane. Well, maybe YOU dump your chapstick. I don't own chapstick and I don't understand why so many women are always applyign chapstick. I have even seen little cases for attaching your chapstick to your purse. Men don't seem to need chapstick. But if you are the kind of person who carries chapstick, then I do imagine you would experience it as a crisis to see your chapstick roll away, just because you had a bag that couldn't stand up to bending over. OK, so let's drop the subject, because the point is, I don't think you are going to lose your chapstick with this bag.4) The strap. There are some bags that when you shorten the strap, all the extra strap just flaps in the wind. This makes no sense to me. Who would want that? This is not that kind of bag. This is the kind of bag where the strap doubles upon itself as it is shortened. The strap itself is of a sturdy but soft material, kind of like a car seatbelt. I will caution, however, that if your intention is to wear this bag cross body, you may find the strap length to be insufficient. I am 5', about 105 pounds, and very little of my weight is in my chest. In other words, I do not have big boobs. If you are a larger person, you should reviews by larger people to see what they have to say about this. I think they may offer a strap extender? You should probably get it. On the plus side, the strap has a snap buckle, so if you have cinched it close to the body, you can unbuckle it rather than struggle to get it over your head to remove. Come to think of it, maybe it's the buckle that allows for the attachment of an extender. Come to think of it, maybe I should try this jawn on over my heavy winter coat to see if the strap is long enough. "jawn" is a word we use a lot in Philadelphia. Oh! And another good feature of the strap is that there is nothing on it that would dig into your spine if you were wear this bag while sitting in a restaurant, leaning against the back of the chair.5) This bag can indeed hold what I consider to be my essentials: phone, drivers licence, credit card, sunglasses, a key. Not your entire janitor ring of keys -- let's not be ridiculous -- but certainly a house and/or car key. You could, if you wanted, shove in a few more things, like chapstick, if you are that kind of person. And I will say, with the sunglasses in it, it is full. Both zippered compartments have slots for three bank cards, although on both sides, the top slot is sewn too tightly to get a card in it. A clear design flaw, but not a fatal one in my opinion, as I may not even use them. One of the main zippered compartnments has its own zipper compartment. I could see this being a useful place for storing cash. The other main zippered compartment has a mesh compartment within. Obviously, this is where you would keep your essential chapstick, if you were that kind of person.Overall, I think this bag offers excellent value for the price, and while I swore off plane travel for the rest of my life, this little bag may change my mind.
