[Universal] So far, I love the backpack. It's compact, lightweight, and the quality is exceptional. Plus, it offers plenty of compartments to accommodate all my needs.

[Zipper] I bough this bag for college in 2018. Little did I know I'd keep the bag this long or that it would become my personal travel companion. I frequently fly across the US for work (think an average of 30 flights per year) and this bag has never let me down. No matter how much I stuff it, it fits in the personal bag checker at my chosen airline and allows me multiple days of clothing and supplies. No other bag compares. When I need to replace it, I will purchase another. It is truly waterproof and stain resistant. The only thing that has broken or shown wear is a plastic buckle that has broken an inner snapping point. I think metal buckles would be an upgrade, however, I plan to attach one myself to repair my bag. It does get heavy when full (as to be expected).

[Universal] This daypack is by far the most versatile pack I have ever owned. After getting it for a recent family trip to Colorado, it proved to me that it is perfect to be used on a hike, as a carry on, to carry your laptop and work gear and it was even used to replace our diaper bag on occasion! The compartments and the comfort of the straps make this daypack a winner for any task. Couldn't be happier!

[Yes] This backpack is so wonderfully designed for people who like pockets and organization. Nothing on the market compares. Mine is over a decade old too and still in the good use. The only thing is the side mesh pocket for a water bottle has torn. But that’s normal wear and tear, I believe. I would buy it again.

[Yes] I have been looking for the perfect EDC bag. I often ride my bike to work. I love the versatility of the bag. I love the look of it. It projects an amazing urban look. Only wish I have for this bag is to have a Luggage strap as I also want to bring it on my travels. Overall still an amazing bag.

[Yes] pockets pockets pockets, best backpack I’ve ever had. it’s perfect for the traveler as well as the commuter. plenty of space for a laptop, books, charger, and all the small things without being clunky

[Black] Have had this bag for my three years in college. It's amazing! My first pro is the quality of material. It has yet to show any wear or tear. I thought that the plastic buckle clips might break after a lot of use but haven't to this day. The bag is great for a laptop, books, pens, cables, and a lot more. You can fit more in it than you think.

I've also used the bag a lot of travel and if you have extra items that don't fit in the bag, the cover flap can be used to store those larger items securely.

Only negative thought I have is, like many others have said, it's very difficult for the bag to remain upright freely. This is something you get used to over time as you simply lean it against a chair leg or wall, nothing serious.

Overall, very satisfied with this bag and would recommend to anyone in school or constantly on the go for business.

[Black] I've used this bag nearly everyday for the past seven years and it is just now getting broken in.

It has been my go-to daily bag since getting it in college. Hauling laptop and books to classes, messenger bag for day-long cycling adventures around the city, personal-item airport travel bag, road trip "essentials" bag, and a daily bag for commuting to-and-from work. I've used the bag in so many ways without any issues with zippers, material/fabric, velcro, buckles or straps. It's remarkable that the bag is just now beginning to look like it has been well loved.

I'm a sucker for purchasing new bags for my gear closet, but this one is so versatile and such a great UX I can't come to terms to replace it as my daily bag.

[Zipper] I was looking for a backpack that would look sleek for work and that could work out as a 2-3 day trip backpack. After looking all around and ordering backpacks from other places, I finally found the one with the Subterra.

Pros:
- Good quality material
- Super comfortable, the back is super padded which is amazing
- Lots of pockets which was something I was looking for
- Easy access back pocket which was been super useful in the subway to get my Kindle out or to quickly get your laptop out
- Design. I love that it looks pretty thin and sleek if you don’t put many things on it (for work). Other backpacks would keep a bulky structure even if they were basically empty
- Big opening zipper is great for packing it up for travel
- Pretty expandable and big of you really fill it up (I think it is more than 25 L)

Cons
- I’ve realized it is sometimes hard to buckle it while closing.
- It only has one outer pocket (i.e. you need to unbuckle it to reach all the other pockets). Would be great if the Velcro flap in the front could be used without having to unbuckle the top.
- As mentioned in other reviews, the outer pocket opens to the outside, which in certain positions feels as if the inside could fall. Never happened to me but I understand it could.

I think the pros definitely outweigh the cons given the research

[Universal] Absolutely love it! It's light and can hold a lot of things. I travel a lot for work between cities and it's perfect for clothing, toiletries, my Mac and gadgets.
