Shimano Pearl Izumi has a life time warranty on their kits for materials and manufacturing defects. I have a favorite PI Jersey purchased from Competitive Cyclist in 2013 that had a heat welded seam below the neck line in the back come apart. CC found and sent a copy of the receipt, which I sent to Shimano with the warranty form in Sept 2020 with the Jersey. Just got it back repaired today, very happy customer!!!
