www.ripcurl.com.au/?wetsuitwarrantyinfoI usually take the suit back to the shop I bought it from along with the receipt.
A friend took an old suit to the Rip Curl store in Torquay and they took it and repaired it for free. They were impressed that such an old suit was still going.
I used to do my own wetsuit repairs but professional repairs are much better.
I've recently had a bit of damage repaired (ie not warranty repairs) and Rip Curl charged a little more than I thought was reasonable. In the past they've done everything for free. It was still not too expensive and is easier than hassling around finding someone to do the job.
