I had a Surf East wetsuit. It was a no-name brand I had never heard of, and it was dirt cheap. It lasted me 8 years and it still has no holes in it!
Henderson is based in Millville NJ. I was surfing in Sea Isle City one day, which is not far from Millville. A woman approached me and commented that she like my wet suit and asked where I bought it, when and if I was satisfied with it.
When I finished raving about the price and quality, she told me that Surf East was a defunct line made by Henderson that was targetted towards the local surfers but never really caught on. They were trying to break out of the SCUBA vertical market.
She gave me a brief overview on the build process that Henderson uses. At the time, she told me all the wet suits were hand stitched.
Anyway, you may not have heard of Henderson, but in my experience, they are a very good name and value.
