I am a carrier--I bring all kinds of things with me when I travel, commute, or even stroll. I have a lot of backpacks that I love, but none were working for my needs from a job change. My partner suggested I check out State. I didn't want to buy another backpack since I have several, but she insisted, so I did. It was beyond my expectations. The first thing I noticed was the quality of the material--it is heavy duty, but soft nylon; the zippers were heavy and solid with a smooth glide. I hadn't seen this level of quality since the 90s. Then I noticed how functional and smart the design is. pockets everywhere you need them, in a variety of sizes, multiple ways to access large compartments. Lastly the size--it's large enough to carry everything you could need, but not so large as to overtake you or the space around you. This is the most thoughtfully designed backpack that I've owned and I sincerely appreciate the quality standards and the mission behind it. You won't regret owning this.
