Picked up one of these for my son, they recently upgraded their original bags. Very impressed though I honestly can't tell how long it might last-the build quality is high. Even though it is the same cordura value as my other bags, it feels like made of much tougher material. All the webbing has full length internal mates, rivets at the point of highest stress, zippers are double stitched, canvas has a heavy duty water repellant coating on the inside. Filler bags are full length, handle wraps are tight, handle straps don't have a ton of slack. The empty bag with filler bags weighs over two lbs, this being the medium size. Internal seams at the ends are bound. I don't need another bag at the moment, but will pick up one of these when I do.
