This could be a great backpack with a few tweaks. I’m a city commuter who works out before hitting the office, and likes to go on a day trips on weekends. I purchased this backpack for two reasons: the separate shoe compartment and water bottle pocket. The shoe compartment doesn’t fit my sneakers! I realize I’m an outlier for a woman - size 11.5W/10M or EU 43 - but I am the average European and American male shoe size which means, if I can’t fit my shoes in there, neither can most of the male buyers. My other grievance is with the water bottle pocket: I can’t fit my 16 oz container in there let alone my 40 oz one. This means I either need a separate water bladder if I’m going on long hikes, or I invest in Tropicfeel’s tiny water bottle which only holds 10 oz of water (which means you will need to be somewhere you can refill if you’re going on a day trip). The only other tweak that would make this bag awesome would be a separate laptop compartment which one could access from the back of the bag. There is an existing laptop compartment, but you have to open the whole bag in order to get to it which if traveling by plane is a bit cumbersome.
