This is probably the ONLY backpack on the market (by Jan 2019) that fits my specific need: [light camera gear] + [urban everyday use] +[short urban travel]. Let me explain.First, I need a bag that holds my camera gear for street photography (2-3 lenses + 1 mirrorless body). All camera bags does this job, but most of them is a overkill to me with too much padded space for camera gear and less organized space for other essentials, such as notebooks, books, kindle, Switch, chargers, cables, clothes... Or they are either not slick enough or too bulky for everyday use. That comes to my second need: urban daily carry. Taken those two needs together, I started looking into 20L bags that have a "thick" main compartment (4-5") so that I can fit a camera cub into it (I'm fine with no quick access to the camera cuz I use shoulder/wrist straps) and have a potential to expand since I also wanted to use the same bag for short urban travel so it needs to be able to fit a few clothes and a jacket. After 3 months of searching (with a $300 budget), I settled to Incase EO Travel Backpack.Pros:1. Aesthetically great for daily urban use2. Fits my essentials without expansion3. After expansion, I can put clothes for multiple days in it.4. Fits camera inserts in the front main compartment5. It is lightweight6. Love the spacious laptop compartment. I can fit my 15" MBP and its charger, a slim book, a traveler's notebook and a kindle in it.7. Love the handles. Very comfortable.To be improved:1. Use better water resistant material, especially at the bottom. Zippers feel okay, but can be better. Clips are cheap.2. Space organization is already incredible, but can be improved. e.g: i) in the front main compartment, all expandable mesh pockets are at the bottom and the space on the top is wasted. ii) make the front pocket (with the sleek horizontal zipper) big, into both the top and the bottom of the bag.3. Lack of a waist strap. Should have a detachable one4. Lack of a loop on the back to secure on luggage handles5. No D ring. Please add some inside.6. Lack of outside water bottle holder. Those large pockets in the front main compartment fit water bottles but it would be great to have a compressible one on the outside (like Aer Travel 2)7. Add a small flat compartment at the bottom for rain cover.8. Add a popular passport pocket on the back.Finally, let's compare Incase EO with several popular backpacks so that you can see the pros of it:vs [WANDRD Prvke 21]Prvke 21 fits my need. Although it has a large camera compartment, other pockets and organizations are good enough plus it's expandable. Prvke is made out of good materials including YKK zippers. However, there is a critical point that made this bag an absolutely no to me: it is not an urban bag; you look like a traveler when carrying Prvke in a city. It is a great adventure bag.vs [Boundary Supply Errant]That bag is a rising star. Boundary made a successful Prima system and is famous for their "nipple clips". This new Errant pack is made out of insanely good material (I bought it so I know it) and is very comfortable. However, I discovered 2 biggest flaws of Errant 1) space utilization: pockets fight with each other for space. 2) CB1 camera cube makes it really hard to open and close the lid. It is a great backpack if you don't have the need to put cameras.vs [Aer Travel 2]Aer has better material and better organization pockets. However, it lacks a main compartment to fit camera inserts and I don't like the look when it's compressed (literally it doesn't expand/compress).vs [Peak Design Everyday 20]I'm a big fan of PD and have multiple their products. My major concern about the Everyday 20 is that you have to use dividers to separate everything and small things may sneak between dividers. For my EO, I throw all the chargers and cables into the upper zipped pocket in the clamshell-luggage-like compartment. Of course, it also cannot compete with the volume of expanded EO.Incase, thank you for making this backpack. Please keep improving it and many of us will be happy to buy newer versions in the future.
