I got this bag to use as an edc bag, and it's perfect. I wanted something smaller than the bag I've been carrying for the last 4 years and this knapsack is the perfect size for what I needed. It fits a sweatshirt, my notebook and a couple pens and pencils, a larger knife that is impractical to carry on my belt everyday, my lunch for work,Swiss army knife, and still has plenty of room for things I may aquire throughout the day. 10/10 would recommend.
