Giordana customer service
I had a pair of Giordana's top of the line FormaRed bibs. After a little over a year, I noticed that the fabric was getting thin in the front upper quad area (an area that I definitely would not expect to be wearing out on such an expensive pair of bibs so soon).
I called Competitive Cyclist where I bought the bibs and told them what was happening. The bibs were about 4 months out of warranty at the time, but they said Gita (Giordana's US distributor) is usually pretty good about stuff like that so to send them back anyway. They weren't "pretty good" about it, they were great. No questions asked they credited Competitive Cyclist's account who then sent me a gift card for the price I paid for the bibs.
I just wanted to say based on my experience that if you are thinking of investing in some Giordana products, feel confident that if you do have any issues with them, they will take care of you.
Also, let me clarify that Competitive said they have lots of folks in those bibs and haven't seen this issue before. So, don't take this posting as a detraction if you are considering those bibs.
