“I had two requirements that were surprisingly hard to find in a bag: 1) I wanted a fairly large rolltop so I can overstuff and the no zipper to slip down. 2) I wanted big stretchy side pockets large enough to hold the largest water bottle. This bag has both. It also has a padded pocket large enough for my 15" laptop, chest strap, lots of attachment points, feels rugged and looks very cool. And it was affordable! I am super happy with it.”
