Nice bag, strong with great features
Color: Grey(small)
The media could not be loaded. I love this sling bag for travel and every day use. I know it says it is for men, but I love it too. This is the perfect sling bag for travel because you can carry all of your essential documents (including your passport) without fear of losing it to a thief. The strap is strong and can't be easily cut preventing someone from running off with your belongings. The zipper can be secured to a metal loop so a pick pocket can't open the bag and access your belongings. There is another small pocket in the front that is secured by snap so you can put travel guides and maps and easily access them. There is another zipper pocket in the back that is perfect for a small wallet, ID, credit cards, cash, etc. that is hidden for additional protection. The craftsmanship and materials are very strong and sturdy. This is also a great everyday bag. ... show more

Love this bag! Highly recommend!!
Color: Black-diy(medium)
Love the size! Am able to fit my book, phone, 20oz soda, wallet and keys in it. Love the hidden back pocket and the security of not only the locking zipper but also the velcro that you would definitely hear if someone was to try to open it. Good quality and very light weight and comfortable to carry, able to switch the strap to either side as well. ... show more

Comfortable, Easy to Use
Color: Teal Blue (Small)
Review Image by Amazon Customer
After my daughter was pickpocketed in Madrid while wearing a fanny pack with the pack/zipper in front, I bought this crossbody sling before heading over there to visit. I only wore it with the pouch/bag in front, across my chest - this felt reasonably secure. Pros: Comfort, vertical orientation (my credit card and ID were tucked in at the bottom- harder to reach for pickpockets), quality, design, strap would be difficult to cut Cons: There are no zippers inside, just well placed pockets. I frequently wished that there were zippers on at least some of the interior pockets for additional protection. If you need a bag to carry a spare jacket or tuck in purchases that aren't quite small, this won't work. But the size was just right for me! Again, only complaint is the lack of zippers on interior pockets. ... show more

Great crossbody bag, used it first for a trip but still use it regularly for everyday life. Waterproof and holds way more than you would think. Lots of small pockets inside and out.

Awesome bag
Color: Grey(small)
I love this bag. I bought it for a trip that I was going on and I knew I was going to be in a lot of crowded areas, so I liked the antitheft features of the backpack. It's very lightweight and small, comfortable to wear but can actually hold quite a bit. I liked the outside snap closed pocket to keep my phone in if I was going to be removong it a lot to take pictures. I don't feel like someone could get into the snap closed pocket without me noticing. I mostly liked it kind of as an alternative to carrying a purse around and it kept my hands free, I felt comfortable having it with me to hold my wallet and just a couple of little things. It was perfect for my trip and I'm sure I'll use it a lot more in the future! ... show more

Not perfect for EDC, but doable.

I ordered this bag a few days ago. It arrived promptly. As with any item I buy for EDC, I immediately start looking for the pros and cons. Let me say that I know that there are other manufacturers that make sling bags made specifically for EDC items. EDC as it pertains to safety and medical items. The problem is that most of those bags are on the tactical end and have MOLLE points of attachment. Such look is a dead giveaway. I rather carry something a bit more inconspicuous. I should also add that this bag will not fit the purpose of carrying my primary tool. I carry AIWB. So, having to gain access to my primary tool is not something that I evaluated. I chose this bag for it's looks and bc it's going to be big enough to fit spare mags, a couple of TQ/CAT, chest seal, decomp needle, CPR mask, medical scissors, wound dressing, band aids, pain killers, antiinflammatories, etc. The bag seems to be made of good light water repellent material. I exposed the bag under the water spout for a couple of minutes. It kept the contents dry. Still, I will apply some 3M fabric treatment spray. I would have liked to see double stitching at the upper portion of the shoulder strap. But, given the way it's marketed, this bag is meant for light use in urban areas. The cons that I found with this bag is that regardless of the shoulder strap configuration (see pics), one the zippers ends up facing the ground. This means that when you open the zippers, one of them will allow the contents of that particular compartment to fall out. This also means that if you decide to carry the bag with the main compartment's zipper facing up (as you swing it in front of your chest), you'll have reach into the compartment with your left hand to reach its contents. For a lefty this is no problem. But you may want to take that into consideration when ordering this bag. As for me, this is actually a benefit as I like to keep my strong hand unoccupied while reaching into any bag that I'm carrying. The above zipper problem could be easily fixed at the point of manufacturing by adding a dual zipper to the main compartment, and or making the opening to the rear (secret) compartment horizontal instead of vertical. I cannot attest to the bag's durability, but I will update if I encounter any issues besides normal wear and tear. ... show more

Good product and effective.

Comfortable to use and was easy to use during traveling. I would continue to use it when not traveling but people look at you funny in the USA.
