The way the straps are engineered across with neck and the top of the shoulders, almost with a cross-brace design, means that those straps never dug into my shoulders. I didn't find, like with many backpacks, that the strips narrowed and twisted up, making a distinct channel in which they can saw and cut their way through my shoulderblades. Instead, the straps stayed wide and in place, and I never had to shift the backpack around, or more likely, just hold one bottom-end of the bag up to help balance it.
The interior pocket of the backpack is huge and has plenty of room for a laptop, notebooks, hairbrush, shampoo, bugspray, shoes, clothes, toilet paper roll, extra water bottles, ipod, laptop charger, voice recorder, snacks and just about anything else you can think to stuff in there at a time. Even cooler, the back pocket is designed to hold your wetsuit, so it's waterproof. So, if you are in the rainforest and need to keep something safe from water, or if your favorite "doo rag" gets soaked, you can toss it in this pocket and keep the rest of your gear safe from that soggy mess.
Now as for the design of the bag, Dakine made this bag especially for project BLUE so they designed the bag to be made from 100% recycled PET bottles, but made without any PVC. Also, all of the buckles on the bag are made from recycled materials. While the bag looks and acts like any other normal Dakine bag, it's made from recycled materials which seem to do a great job holding up under any conditions.
You can purchase the Dakine Oceana backpack online now at Dakine or at project BLUE. Since this is a special project BLUE pack, $2 from every pack will go to the Surfrider Foundation. Each backpack retails for USD$75. Happy Trails. :Dakine :project BLUE
