I've been using this backpack for a little over a month now. While it's certainly getting the job done, I can't say I love it. I travel via train and longboard to/from work every day, so I needed a good commuter backpack. Some key features I was looking for were size, durability, pockets, and room for a bicycle light. I needed a bag large enough to hold my uniforms, a spare change of clothes, shoes, snacks, etc. It was also a must to find a pack that had side water bottle pockets for quick access that would be large enough to store a 32 oz. Nalgene bottle and a 17 oz. Hydro Flask food flask.
While I am happy with the bicycle light attachment and side water bottle pockets (success for both the Nalgene and Hydro Flask!), I am not 100% thrilled on the design of the sizing. The backpack is definitely large -- it fits a decent amount of gear, but it is pretty slim. It gets its size in its length and width, but it is not very deep. It's long in length so stuff seems to fall into a "blackhole" and since it's not very wide, you'll have a narrow opening to go searching for everything. (In this case, I'm referring to depth as the distance the pack extends outward from my back; length as the distance from my shoulders to my hips; and width as distance from shoulder to shoulder.) Lucky for me, I have broad shoulder and a broad back, so the large width isn't too much of a problem for me, but as a women's backpack, other women with smaller backs might find this pack a little large. Additionally, the pack panel has a thick padding for added comfort (nice!) but it is lined with a pretty rigid plastic of some sort, making it a little cumbersome when trying to pack it.
Another issue I have is that the bottom of the backpack angles upward a bit, meaning that the bottom of the bag does not sit flat on the ground. With the rigid plastic lining on the back padding, the pack does not sit up straight when placed on the floor or on any flat surface -- it will tip forwards.
Overall, it is a durable backpack that will certainly hold enough stuff for a day trip as long as you don't mind digging deep for your gear. I purchased mine in Lagoon Iridescent Print/Asphalt Grey and it's a very nice color.
