I travel all the time and love taking photos of my travels. I carry a 7d, 70-300, 17-40, 50, 10-22 and a 28-135, plus three hard drives, cords, eyepiece for when I shoot video, all my nd filters and other stuff I'm probably forgetting. I also bring my computer, iPad, pens, note pad and it still has room for snacks, water, sunglasses and more. Not to mention, when you ride, you can strap up your boards easily on the sides. It's comfortable and just fits in the overhead bin. It's also pretty handy when you go somewhere skethy and don't want to bring your camera, just take out the block and you're good to go. I obviously highly recommend this pack!
