Love this little bag!I live in the city and ride public transportation and then walk to work, and I needed a small backpack just big enough to hold my daily needs, without being too big or cumbersome or heavy or obviously empty and this bag is absolutely perfect!It arrived on Saturday, I used it on Monday which turned into a busy day of riding to work, then riding the train downtown and back and this bag was great! Just the right size, the water bottle pockets actually fit my water bottles (Hydro Flask bottles).At the moment I'm only using the bag for urban trekking but I can't wait to use it while hiking when I finally get out of the city.So light weight that it doesn't bother my back, but the construction of the bag is sturdy enough that I have every confidence in it's endurance, and finally the shoulder straps are absolutely perfect! Just the right width to be comfortable without chafing, just the right weight to not be painful or flimsy.All told, I am so happy I bought this bag.
