Leash broke on 9/26/17, biggest day of surf in recent memory ever in my favorite spot. I omitted this story from the entry about Tuesday because it was a non-event, actually, overshadowed by the gigantic endorphin-fueled excitement of that day's other events.
I contacted custom X about what happened to my bicep strap saying that it was probably not designed for such conditions but within a few hours, they wrote back and were sorry that it happened to me, said they had never seen it happen before, and offered to give me two to replace the one that broke.
I also work retail, and I'm just puttin' this out there: rarely have I ever seen such prompt, polite, human-oriented customer service in my life.
Their products are of the highest quality, but their customer service is of an even higher quality.
I am now a customer of theirs for life. You can mail order their stuff or get it from OBBC Surfing products in cape hatteras, NC. Lynn Shell is the owner, and you can find em online!!!
