Well, I've now had the Neosport for about 10 months, but only put about 5ves on it. It started falling apart within 20 dives. Absolutely the worst wetsuit I've ever owned (and I've been diving for 48 years now). Initially it developed tears around both kneepads despite my care in putting it on. After about 20 dives it began showing tears on the INSIDE liner. I rarely pee in my wetsuits, so uric acid is not to blame.
Unless I have a lemon, I will NEVER buy another wetsuit in Henderson's Neosport line. This is even worse than my Seaquest X-Flex that started falling apart after 50 dives. On the other hand, my Tilos wetsuits have given me as many as 650 dives (despite the fact the legs eventually fell off).
Fortunately it has been warm enough the past three months to wear my 7year old Tilos 3/2mm (which shows NO tears at all), most recently with a 3mm hooded vest. It's warmer than the freaking Neosport!
