I'll be boarding right through the winter this year and I want to know if I can get away with a 3 or a 4mm full suit for Rhode Island this winter or should I buy a 5mm? Second, who makes the best suits for boarding in your opinion? I was looking at these but I'm not too sure they're thick enough.
Some guys actually wear 4/3's all winter around here believe it or not, but I'd recommend a 5/4 minimum, 6/4 if you want to be a bit more toasty and don't mind losing a little flexibility. I find the 5/4 to work perfect for me, but for RI a 6/4 is probably the call. 5mm boots ans gloves minimum, although you my find you want 7mm.
