I've had this bag for about 6 months now. Here are my thoughts.
○ Pros: The pack is light, the lightest of the backpacks I own in the 35-50L range, including some smaller packs from Osprey. Due to being longer, it's pretty narrow & because of the lighter materials it compresses very well when not full. This means it's better for me as an EDC than other packs in this range. The water bottle holder is decent & the compression strap can make sure it stays secure. Not only that, but this is one of the few tactical-style backpacks I've seen where the compression straps are built so they don't prevent access to the main or front admin compartments (it can prevent full access to the side admin compartment, but this isn't that big of a deal). I understand for some that compression straps can act as a sort of theft deterrence due to the extra step it takes to get into the bag, but I really like this setup & wish more bags would do it this way. The j-top clamshell opening allows for top loading, fully-open loading, & even some side loading access if you place the zippers right. The admin pockets on the front & side give some good options for creative packing, & the side admin can also be used as a secondary water bottle pocket for a thinner bottle. The secret pocket in the back harness is bigger than it looks & perfect for my wallet, phone, etc. The soft stash pocket on top is roomy enough for several fragile items. The mesh pockets in the main compartment are awesome, & sometimes easier to throw my tech stuff in than the admin pockets. The laptop compartment fits my 14-inch Chromebook pretty easily, & has some good suspension away from the bottom of the bag. High-vis lining with dark-exterior bags is always a plus, & the topographic map design is unique. The back harness is very comfortable, with soft but supportive & breathable mesh that hasn't left me too sore even when fully loaded out or left my back too "swampy". The hip belt is pretty decent for securing the bag while bike riding but I usually take it off anyway. The sternum strap fits nicely & is pretty adjustable. I love the redline color scheme; it looks just unique enough to stand out, but isn't in-your-face tactical.
Cons: Not having a separate laptop compartment means you've gotta watch where you place the bag down in wet conditions, especially if there's standing water, because the bottom grommet can allow water to seep in & potentially damage any tech inside. The clamshell opening helps packing better, but because of the bag's narrow shape (longer vs wider) it's hard to pack bulkier items (ex, my large lunchbox). Because of this, the bag often seems more like a 35-38L bag than a full 40L. The admin pockets are relatively thin & built so that once you put something even mildly bulky in one pocket (like my asthma inhaler or my mobile charger), the other ones become unusable. The bag is flexible & has enough give to stretch the main compartment & use all of the available space it has, but doing so will keep you from using the admin panels for much other than a wallet, maybe a phone or PC charger charger, and some cables. I can & have added one of my Maxpedition pouches to it, & it fits well enough to cover most of the MOLLE for a slightly more grey-man look (although one could argue that attaching pouches to the back of a bag screams "tactical bag" the same way MOLLE does). Also, this disrupts the slim profile of the pack. Finally, although 3V Gear does a great job of adding strap keepers to the back harness straps, the compression straps, & even the hip belt, they somehow forgot to add one to the sternum strap. Not a huge deal for me, as I just added my own Velcro ties to achieve that coveted dangle-free experience, but it seems like a strange oversight for a company that is obviously trying to distinguish it's gear from the other more expensive stuff out there.
Even with these cons, this is still a solid EDC/daily commute backpack, and I've grown to really love it. I'll switch it out with another bag like an Osprey, 5.11, or North Face every once in awhile. But I keep coming back to it for its practical organization, solid amount of storage, lightweight & comfortable handling on my back (especially when stuffed full of tech gear or groceries on the bike ride to/from work), along with the cool-looking inner/outer styling. I highly recommend this bag for virtually any use-case scenario, with the possible exception of a workplace where business professional-style attire is expected.
