This is my second hikpro backpack. My first one started to rip after a year of consistent use, so I upgraded to this larger pack. I love the way it folds up for easy storage. This bag has an XL compartment that easily fits a 13" laptop, water bottle, book, snack, and more. 30 L is a lot of space, and this bag economizes it well.
If you're looking for a bag with a lot of back/shoulder support, this is not for you. This bag offers virtually no support, though the straps are padded a little. The main feat of this bag is its ability to compress. Great for a day pack or emergency bag!
