I have had my PNT bag (predecessor to LW) for 16 years. The only thing I have done to it in the whole tenor was to have the corner of the main zipper sowed after it tore away a few years ago. When they fixed the zipper they also gave me a Velcro cover for the foam handle. I would buy another on in a heartbeat if mine went south. But at this rate it will be a while before I have to think about shelling out the $$$.
