This thing is awesome. The high quality zippers that Mystery Ranch uses make a huge difference in securing your pack. The well thought out shape and to load design allows more room than traditional side zipper packs. It fits very easily under airliner seats. I’m very pleased with this bag!

Robo flip

Bought this for my grandson. He was carrying too much weight in a crappy backpack. This one fits just what he needs and centers it straight up and down his back. Result is much less back pain. Thanks

Ultimate Florida outdoor Dad bag!

The top loading open formst allows me to jam kids jackets, waterbottles and tablet for airplane travel while easy to access in the small floor space between your feet while sitting on the plane or bus. Then on weekends I can throw tackle boxes, a telescoping fishing pole or even line it with a contractor bag if i want to haul back sour oranges, a few fish or bonus squirrel or rabbit. Easy to clean out and zippers are overbuilt how I like them. Love the foam in the back as it adds structure and the daisy chain for lashing. I love good gear and this is one of those pieces that just nailed it. Simple look but perfectly thought out and executed! Pro tip: a bottle of bourbon fits in that internal sleeve perfectly.

Durable and spacious with style

This backpack got me through 3 years of law school carrying lots of heavy casebooks and it's still in near-perfect condition. It also fit my lunch, water bottle, computer, mouse, charger, rain jacket and a few other misc. items. I highly recommend this bag.

Great EDC Backpack.

I am so happy I bought this backpack, not only is it a great edc backpack but it’s well built and great quality. I use it everyday for work and the gym. It’s nice and compact, I have no issue fitting everything I need for the day in.

Perfect commuter

Keeps everything internal including water bottle, which I prefer. Adequate storage for a laptop, Ipad, accessories and documents. Side compression straps keeps the load close to my center of gravity. Added an after-market sternal strap to secure the pack and relieve my shoulders. The usual Mystery Ranch durable construction is a definite plus. Thank you for a great product.

Excellent high quality product

I've used this bag as my EDC for four years. I'm a university professor, so I wanted a bag that would be practical for getting to and around campus but with an evident level of quality and style that would transcend the collegiate. I love the smooth-action wide-tooth zippers, the all-metal hardware, the cinch straps that keep it tight when not stuffed with books; the laptop sleeve that doesn't go all the way to the bottom (so I can set it down without worry), the smaller tablet pocket (which I use for valuable documents or a passport), and of course the bottle sleeve (where I also keep my laptop charger) --- these all provide a high level of organization. The top pocket does manage to hold a bunch of stuff and keep it from falling out, but in black it's also sometimes a challenge to see things in there. Finally, when I am overloaded with stuff, I can hook my lunch bag onto the outside with a carabiner. I can't remember the last time I went four years without searching for a new EDC, and I'm happy to say that this one is wearing quite well, so I won't be hunting for a replacement anytime soon. In fact, I got online today b/c I want to buy one of these for a friend.

Great minimalist bag

Bought this in 2020 when I started a grad program and wanted a new bag since my old one was so beat up. This has held up great, the materials and construction are super solid. The internal laptop pocket is perfect and I also really like the smaller velcro pocket for keeping noteboooks. I really like the minimalist design overall and the internal water bottle sleeve is actually better than I would have thought. Have taken the bag on all sorts of flights and weekend trips and it barely shows any external wear. Definitely sold on the MR brand and will consider buying from them in the future.

Perfect laptop bag

I bought this for work. Perfect size for my laptop, iPad, lunch and a coat. I needed something with more pockets than my shoulder pack. I take this bag to do wetland surveys and bush wack through thick dogwood. The material is very durable. I am back and forth on whether I would like a slightly bigger pack maybe 30L but it seems to carry everything I need.

Perfect "Modern Briefcase"

I use this pack to carry a laptop, tablet, 1" binder, pens, chargers, and a 1.5 liter Nalgene. The interior water bottle holder works perfectly for my Nalgene. With all this in it there is still room to fit my Yeti 32 oz tumbler at the end of the day. This pack is truly perfect for both the college student as well as the modern professional.
