Depending on why you bought this, there may be a learning curve to using it. Is it worth $170???MY USES/NEEDS:I work at a lab so I carry my typical "EDC"/"Office Stuff" with me all the time. I'm not packing lab coats and safety goggles in here. I needed a typical backpack for going to work but could pull double duty when traveling on weekends or overseas.CONS:I find it's lack of easily accessible storage through the top to be an issue since it only opens from one side to fold open (like luggage) rather than unzipping halfway down on either side like a standard backpack.The lack of a water bottle holder is also a bummer honestly.If you plan to use it as your daily driver, expect to either travel light or relearn how to use it like I did.PROS:Literally everything about this bag screams "quality". If you're well traveled, the above con doesn't apply to you and this bag is perfect for storing essentials like clothes, toiletries, etc.I'm able to store my most-used daily items in the front pocket and my laptop and tablet stow easily in the dedicated pocket.After some initial struggle, I have my less-used items in the main compartment attached to grid organizers so I can pull out the whole panel, find what I want, and put it back with ease.The bag feels good all over, very secure stitching, toggle points are great for hanging any extra gear, straps feel VERY comfortable and well made, fits snuggly against the back with a relatively low profile, handles on all sides are AMAZING to use, and the rain cover fits beautifully and looks just as good.The straps stow away very nicely which is gonna be awesome for carrying it around when I don't wear it on my back.CONCLUSION:I didn't want to like this bag...I was already unsure if I should've spent $170 on a freaking backpack when there were others that cost $60 that would do the job.The level of thought that went into it's design and the incredible quality is what's making me keep this bag. They're clearly designed to last a lifetime. Plus it looks AWESOME ngl.
