+1 for Peak Design. I have yet to use the warranty, but the thing still looks new after lots and lots of travel, shoving under seats, tossed into train and bus overhead bins. The only real wear is the corners of the metal clip for the flap. Expensive, but in this case, you get what you pay for.

Yeah, they didn't question my warranty claim at all IIRC, and breaking the zipper was actually my fault. I had overstuffed the bag while in a giant hurry.
