  • Its classy, beautiful and versatile.
Its Peak Design… I love everything about this company. 🖤 This bag is awesome. Lets just get that out of the way. lol I usually stick to smaller bags. 25l and below. But I needed a bigger bag that I was not going to be carrying around all over the place. I wanted something to leave my extras in it. This company offers lifetime guarantee. That alone wins a ten star to me. But the bag earns it as well. Its beautiful. Classy and versatile. I can use it as a weekender. Zero camera gear. I can use it to travel with camera and my clothes and personals. You have to love that kind of bag. Plus all the accessories that can be personalized in it as well. Pro tip: I have a Shootsac Lens Bag that I store inside the laptop section. It fits perfect. However, I wish the laptop section had a zipper closure. My only complaint.(Well maybe a little more padding on the shoulder straps would be great) But for what I am using it for. Its awesome as is. However, I don’t trust it when I am flipping it open. (The laptop area) So I use the Shootsac laptop sleeve because its well padded and zips closed so that if my laptop does slide out. Its extra protected. Hope that makes sense. Its such a beautiful bag. I highly recommend it! ... show more

  • Psst... Keep Zippers On The Down-Low
This pack is almost perfect (almost). There is a pouch area you can access in the front, and a left side & right side zipper access to the main storage area. Those zippers are just behind the front access area, so if you get this pack the day before you travel and then try to sort it out under the gun of airport travel.... It can seem like a confusing array of zippers. But once you sort that out, you're good. The tricky part is the back access panel. You have to lay the pack on its face to open the pack completely using the 2 zippers that extend around the perimeter of the pack. I would typically set these zippers at the top or 12 o'clock position and place items I might need while traveling on top, that way I can dig into the pack and grab whatever it is in a hurry. Thankfully, I bought the matching packing cubes and shoe pouches, because those damn zippers opened up on me, not once but twice while scrambling at two different airports. The cubes stayed put, and I lucked out twice by not dumping my clothes behind me while scrambling to catch a connecting. I'm a slow learner, but after the 2nd offense, I now keep the zippers down hard left, with no other issues. But I should add my REI pack functions much the same, and it NEVER unzipped itself while traveling. That zipper cost this pack a star. Otherwise, this pack is well made and yes, I'd buy it again, I just wish the main-hero-mission-critical zippers were of better quality (like the REI pack uses). The zippers work great as long as they are in the down position; otherwise, when jostled, they can fail spectacularly. ... show more

  • High Quality
Good materials. Made with care. It’s a little over priced in my opinion but it is high quality. Good strong zippers. It’s a bit heavy. Can fit a lot of stuff in the main compartment. The front pocket has a divider that folds up to add more capacity to the main compartment. Overall I’m very happy with this backpack. ... show more

  • This bag works and I can see value from using this bag over a long period of time.
I have an older (and cheaper) backpack that is smaller and a bit ragged from relatively small amount of use. Bought this backpack for an extended trip. Needed the room. Appreciated the design. Hoped for more durability. Needed to fit under airplane seat. In use it worked. Held 2 laptops plus panel for second screen along with a lot of gear. Held up great. Appears water resistant as I also had to walk in the rain with it on; everything stayed dry. I bought cheaper compression bags to compartmentalize gear in bag (the specialty bags this vendor sells are overpriced). On initial look, zippers appear weak but after actual use they are solid. This bag works and I can see value from using this bag over a long period of time. ... show more
