I wanted a bigger backpack for cycling around with my gym gear, extra clothes, lunch boxes, water bottle (the pouches on the sides can fit my 1L bottle), laptop and random assortment of small tools for my bike. This bag can take all of these and additional shopping without issues, and the net outside can take little bit of extra that wont fit in the bag itself. The bag is very comfortable to wear as well. The only problem I now have is that I can carry so much stuff the bag gets too heavy :D The small pockets are also exactly what I wanted: 1 bigger and 1 smaller on the outside of the bag with zippers, and one net pocket inside the bag. I'm very happy with this purchase!
