Review: Great work bag. - Roomy, lots of pockets & storage. Lightweight & looks good. Like the shoulder strap which is comfortable. Holds laptop and everything else needed for my job. Hasn’t rained yet, but I like the waterproof feature. It replaces a bulkier bag I had previously.
Review: Insanely Durable for the price - I got this bag after multiple bags of mine had either the straps snap, or the bracket holding the strap to the physical bag breaking. This bag is made of a nice and thick fabric with great stitching and ALL metal hardware making it able to withstand weights up to 30lbs in my experience. I have used this bag for work, carrying 2-3 laptops with all of their hardware, travelling with clothes, laptop, switch, cables, and anything else I could fit in. The expansion zipper is great and adds more room. When using it for travelling I have had no issues with it being used as my carryon as well.

### ⭐⭐⭐⭐⭐ I should've bought one sooner
*by F***S on January 29, 2021*

This is like a piece of professional luggage. The quality of the zippers and stitching are what you'd only find on higher end luggage. Great value for what these cost. It made me realize how poor the quality of my previous two laptop bags were. Quality of construction and material have me expecting this thing to last me for a decade (my previous bag was far inferior in quality and lasted me about four years). Looks very compact when it arrives, but when its removed from packaging and filled with your stuff it expands plenty to hold all your items. I'd honestly give it six stars if I could. My only gripe is every single compartment is zipper based... there is no "flap" compartment for easy access to your more commonly used items. However, this will likely pay off for me when the bag takes a spill off a car seat or in an airport and gets upended, as all contents will remain in the bag because of the zippers. But I kind of liked having a flap compartment to quickly drop my phone and keys into the bag. But the quality of this one is so great, I will learn to use the zippered compartments for stuff like that. It really is a great buy for the price.
