This backpack is used in a variety of ways definitely put through the ringer on a weekly basis. It'll go from hitting the college campus in and out of rooms all day to work late at night. I find the straps are extremely comfortable for long wear for fast pace walks. There's an ease of use that naturally comes along with the roll - top feature allowing me to get in and get out of the bag quickly. Touching on the exterior honestly it's a solid rhino built bag. This thing is solid and sturdy it'll handle a fall, scuffs, minor abrasions. It's pretty good at handling wet garments when i'm coming from the beach and doesn't hold sand onto it. Easy exterior wipe down.
