I already own a Vertx Overlander 45L pack and have been so impressed with it that I decided to get this smaller 28L cousin. I am really pleased with this pack; it is quite a voluminous 28-Liter pack and works wonderfully as a travel pack, mission pack, range bag, or carry Bag for an SBR. Pros: - It is a true 28L pack that will accommodate a wide range of essentials. With one main dump compartment, a front pocket, and front dump kangaroo pocket, along with a pair of side water bottle pockets. - There is a well stitched top grab handle. - The shoulder harness is well padded, and it has tabs for routing a hydration hose, and each shoulder strap has a built-in stretchy accessory pocket (the pockets are not large enough for a phone, however, but more sized for an energy bar or flashlight). - Generously sized exterior water bottle pockets are large enough to hold a quart-sized water bottle. - There is an internal 15-inch laptop sleeve that you can remove if you do not wish to use it. - Very well-padded and stiffened back-panel that creates some structure and prevents the contents of your pack poking your back. - The interior Velcro is a lighter color than the exterior nylon, making it easier to locate specific contents within. - Comes with sternum-strap to help keep the shoulder harness from sliding off your shoulders, and a removeable waist strap to keep the pack from bouncing when on the go. - It is made of durable heavy-duty nylon materials and the stitching appears robust and durable. - Lockable beefy Zippers and the zipper pulls don’t jingle. - It is hydration bladder compatible with a hanging tab and hose pass-through port. - Has a full-length Velcro backing on the main compartment, and a strip on the outer compartment, for adding the Vertx Tactigami or aftermarket accessories. - The bottom inside of the main compartment has a Velcro opening so that you can replace the stiffened back panel with an armor plate if you so desire. - It’s fairly lightweight for its feature set at around 30-ounces. Cons: - The outer pocket has an L-shaped zipper. I would have preferred it open all the way around on both sides of the pocket with dual zipper sliders. - Although the rigid back-panel is great at keeping contents from poking against your back and there are some airflow cutouts with mesh sections, you’ll still sweat a lot in hot environments. More mesh would likely be better. Despite my nitpicks, it is a really nice pack that is great for inconspicuous travel, mission specific tasks, on the range, or as a bugout bag. It is admittedly pricey, but Vertx is a well-respected and well-established brand in the tactical world that makes high quality gear that is regularly used and trusted by government agencies.
