Top critical review

I was very excited to receive this backpack. After doing a research on different every day carry bags online, I settled on the Korin Flexpack pro as the one to purchase. Packaging was nice and upon first inspection the bag looked great. However, things started going downhill from the first time I tried opening the backpack.
The zippers are extremely stiff and not user friendly. Not sure if its solely because of the angular shape of the bag, but the zippers stuck constantly and it took me pulling down on the full front of the bag for it to completely open.
Starting with the back inside pocket, my 13in MacBook Pro fit just fine (as the back sleeve is measured to fit up to a 15in laptop). However, my iPad Pro which has dimensions of 9.8 x 6.8 just barely fit in the 10 in tablet sleeve. I had to take off both the slim back case and Smart Keyboard case to get it to fit.
The inside side zip compartments are good in theory, yet the right compartment section made to fit an external battery was too small to fit my go-to Anker 26k power bank. The charger fit in the sleeve but the cable which is threaded through the bag for external charging wasn't long enough to reach the top of the power bank. Plus, the side compartment wouldn't zip up properly. Luckily, I had a smaller power bank I tested it with to see how the external charging port worked. As someone else's review mentioned, you definitely want to have a power bank that doesn't need to be clicked on to begin charging or else you'll wind up needing to open the bag up to access that power button before being able to use the outside charging port.
Which brings me to my second most despised feature: the outside cover which protects the external charging port. this cover is so tightly closed (I'm guessing for water resistance) that I wound up bending two of my nails back trying to open it. I had to use a decent amount of force to get it to open each time I tried. I wound up opening and closing the port cover at least 20 times in hopes that it would begin to loosen up a bit over time.
Another reason I was very interested in this bag was the outside shape and design. It didn't look too bulky, and the sleek look gave it some clean lines. Those clean lines get pretty warped though once all your items are filled inside. By filling in both inside sidewall compartments (right battery compartment, and left computer accessory pocket) it begins to really affect the outside shape. Using either external side pocket further bulks out the bag's shape resulting in a blobby oblong shaped bag when you zip it all up.
I did think the insulated bottom outside compartment was nice, and it surprisingly fit my 32oz Hydroflask with ease. Keep in mind, however, that utilizing this compartment cuts about 1/4 of the main storage space inside the bag, and requires you to stack all your other items on top of whatever is insulated inside that side compartment.
The TSA approved lock on top also seemed to work well and had a nice secure "click" sound when locking the zippers in it.
To give you an idea of my EDC items here's what I tried to make fit inside:
MacBook Pro 13in
-Charging brick +cable
iPad Pro 10.5 in
-charging brick +cable
32 oz Hydroflask
Anker 26k mAh power bank
Lacie Rugged external hard drive
Sony over-ear Noise Cancelling Headphones
smaller items (pen, usb C dongle, Apple Pencil)
I tried at first to also carry my Nintendo Switch but quickly realized that wasn't going to happen.
I really wanted to like this bag. I actually spent over an hour organizing and reorganizing my items inside to try and find the perfect fit that would allow me to carry everything without making the bag look blobby and weird from the outside. I just couldn't find the perfect fit.
I'm sure this bag works great for some. I just expected a few higher quality materials (better zippers, easier charging port access) as well as a sleek design (without compromise) for the $165 price point.
Hope this review was helpful!
