IME Patagonia's warranty is essentially a "no questions asked, repair, replace or refund" policy.

I had a dog tear most of the lining out of a ski jacket. Sent it back for repair a few years later after it had been out of catalog for at least ten years. Included a note that I was happy to pay for a repair. Instead got a gift card for the full purchase price of the garment, which IIRC was over $300. Very nice service.

Haven't had any Patagonia luggage but I'd be surprised if they didn't take care of the customer in similar fashion.
