I've owned nothing but rip curls for over 20 years. Never had a problem. I'm mental about caring for them, fresh water rinse each session, wash them in baby shampoo 1x a month, never dry in sun, hang dry properly. My suits last for about 4-5 seasons before the seams wear enough that I have to touch them up with repair glue.
That said, I just shipped my 3yr old winter suit back to Rip Curl for a major neck seam tear, I caused by rushing one morning. Was quoted $35.
Although I do find newer rip curl and oneill gloves and boots don't last at all, they leak after one season.
I used to get 10+ years out of boots and gloves - would only replace them because of stank. Now they're crap.
like Gfootr, i've worn only rip curls for the last 10 years or so & never had a problem (& while i take good care of my suits, i don't go to the lengths he does). their warranty policy is second only to patagonia's. send it back & they will fix it.
what rip curl suit is it, out of curiosity?
