I can't comment about durability yet as I just received these but my hopes are high given I'm still wearing my original Alturas pants. Even though they are still kicking, I wanted to try out the fit of the new 308 pants and I really liked the new Walnut color. I do like the higher waist of the 308 compared to the Alturas and if I had to or wanted to wear a belt with the 308, it would sit above the hip belt of my pack, instead of directly underneath the hip belt like with my Alturas. I also find the material/fabric of the 308 to be slightly lighter and more breathable than the Alturas- I'm certainly looking forward to the side vents on the 308 when the weather heats up. The fabric of the 308 is still stretchy and moves with me, but its not as stretchy as the Alturas fabric. This makes it feel a little more substantial if I wanted to say, appendix carry off a belt. I like the styling of the pack pockets on the 308. I don't find them particularly useful or accessible, especially under a pack, but they just look better than no pockets like the Alturas. The Alturas did have convenient cargo pockets that held my phone easily on the side of either leg, whereas the 308 have a carpenter style pocket on the back side of the right leg that holds my iPhone in a slim case. I'm not sure it would fit an larger format iPhone though. Since my iPhone is all I really carry in my pants pocket, I'm not bothered with the loss of a cargo pocket on either side, but since the front pockets are higher with the higher waist and have a smaller opening, they don't quite make up for the loss of the cargo pockets. I was in between sizes on the size chart. I originally went with the bigger of the two to have room to layer, but that also led to a comically longer inseam. I ended up exchanging for a size down for a less baggy fit and less excess material around my boots. I feel less need for a belt in the smaller size whereas the larger size was too baggy at the waist and almost required one. Overall, I like the fit and fabric of these better than the Alturas, but I dinged a star because I'd like to see a more utilitarian pocket layout and short-regular-long inseam options for better fit.
