Back in Sydney I'd get cold in my O'Neill Psycho 2 3/2mm after a couple of hours in 18º water and 10-15º air temps. And South Coast winter trips I'd be pulling on the booties when the water hit 16º. Now I surf in my Seventhwave 3mm Viper
and I'm good on what I've come to call 10-10 days. That's 10º water and 10º air. I am wearing booties, gloves and a hood on these days but I'm comfortable. The booties don't come on until the water temp is well below 15º. Hood at 12º and gloves at 10º. Before I moved here (Christchurch) I was imagining a 5mm wetsuit and thinking I wouldn't surf much over winter. Now it's a whole new world. My wetsuit is so warm I'm thinking of getting a 2mm version for our summer here in Christchurch that's 18º water.
So thanks for the great product. Totally worth the money. And for all the Aussies out there, the exchange rate makes them about the same price as any other top line wetsuit, and I don't think any of them come close to being as warm.
