Last time I needed Dainese leather repair it was done through https://anthonysleatherworks.com [email protected] Anthony's Leatherworks 3401 E Coast Hwy, Corona Del Mar, California 92625, United States 949.486.9000
Anthony's does not handle D-Air repair. Dainese has their own tailors in house now in Cali. Anthony's is a solid option for general leather suit repair, but you need to work with Dainese USA for your D-Air repairs. Where did you buy your suit?
I sent in two suits same box. One was repaired under warranty and sent back. I haven’t heard anything about the one that needs the airbag replaced in over a month and I sent an email every week for the past month and a half with no reply.
