Good bag, replacing parts is a process
Bought a burnt orange version bag in 2022 and it's been put through a lot and held up really well. At this point my only complaint is the rail system for the front straps. My sternum strap broke off, which considering the weight and tightness I've put them through, doesn't exactly surprise me. Going to replace it, but I know it's going to be a hassle to get on, per the comments on this specific aspect of the product as well as my prior experiences with the front strap rail. The problem is, or really the benefit, is that once that sucker is on, it truly is not going anywhere. And seems more of a design victory than a flaw, despite the effort of replacement. Even pushing it up and down is tough, but as this is only my bag and setup for me, they've stuck in place perfectly. This feels like a bag I can get five seasons out of, with some minor repairs. One note, I did cut off the waist straps on my bag because they annoyed me to no end. If I bought this same bag again, which I probably will, I'd probably give them a go but likely would cut them off again. Zippers have held up very well under a lot of pressure, too.
Nice day pack.
I bought this pack as an alternative to a Zulu 30 that I regularly use, because I wanted a smaller pack for times when I'm not the family pack horse, and to be sure it would fit as an airline carry-on. The pack carried well, even pretty well stuffed with a fleece, rain gear, miscellaneous personal stuff, and lunch. There's no raincover, but it seems to be fairly waterproof (I wouldn't trust it unaided in a major storm or full immersion... but did well in lighter rain and on a sea kayak without a cover). I was disappointed that the side pockets don't fit a 1 L Nalgene bottle...
Nice smaller day pack
I purchased this as alternative to a 35 L Gregory Zulu (too big for some purposes... but if you're the packhorse for the family...) daypack. No included raincover, but it's reasonably waterproof based on a wet week in Acadia National Park, and you can add one. Over all, a good size for day trips with basic gear (jacket, rain gear, lunch). I found it carried well for me, and I didn't really use the waist belt, which does stow nicely into the pockets provided. I was disappointed that the water bottle pockets on the side don't fit a normal 1 L Nalgene bottle.
My go to everyday backpack!
I’d been wanting a backpack that could be multifunctional - work, outdoors, etc. This bag exceeded my expectations!! The side mesh pockets are big enough for a tall 48 oz Nalgene bottle, the small front zipper pocket can fit a Iphone 16 Pro Max, and two separate deep pockets for essentials and a hydration bladder (not included)! The straps are comfortable and easy to adjust. The mesh pocket in the front is an added benefit for stuffing things plus easy access. I highly recommend this backpack for beginners or experts!
Great bag
This is a great bag. I bring it to work. I know it isn't really designed as a laptop bag, but I can't stand the bland and dull looking laptop bags everyone carries. I got the Moab brown and it looks amazing. The colors are what brought me to the bag, but the durability has been great. It gets tossed around my truck, hung on the wall with way too much weight and the pockets stretched with a water bottle bigger than should go in a side pocket. All of the stretchy pockets are still stretchy. The zipper pulls are great. The top zipper gets stuck like a sleeping bag zipper from time to time, but other than that, I have had no issues with daily carrying and abusing for about 6 months. I hope it is with me for much longer.
Poor quality inside lining
At first glance this is a great pack with lots of pockets for organizing the stuff you need for a day hike. Unfortunately, after just one use, the inside lining has started to peel where my camera rubbed during a 5 mile hike.

Very good quality workmanship in the construction, could use a little more room in the stuff-it pocket
