I used this pack backpacking through Asia for two months. I found that 15kg was my max ideal comfort weight. I was so rough with the pack and it still doesn't have a single snag. It was the perfect size and I had bulky things packed like my camera, hiking shoes and the weight always felt evenly distributed. It's really easy to adjust to fit you perfectly which is great as I can adjust it so all the weight is on my hips and not my shoulders - as I have a small frame this is really important as my shoulders hurt quickly if they are carrying a lot of weight. I'm going to take it on a multi day hike soon and can't wait to try it out for hiking as it has a built in sleeve for a water bladder. Highly recommend this pack!
