i paddle 3x a week in Puget Sound, all year, rain, wind, or shine. i usually wear a drysuit as i prefer rougher conditions and surfing rather large freighter wakes. i also surf kayak on the coast.
i'm on my second dry suit, but am tiring of the maintenance, the 303, gasket repair, constant cleaning, etc. recently, a board surfer friend suggested a new suit by Xcel, called Infinity, saying it keeps him toasty warm in the winter (immersed as surfers usually are), but had great flexibility. i demoed one, and agreed. in a float test after my paddle, i kept very warm (and you do float) and dry, as dry as a drysuit. no flushing. flexibility was no better than a full drysuit with a few under fleece/poly pro layers, maybe better, less fabric to get in the way. holes? no leaking, it's still functional. no maintenance.
cost, $300. http://www.xcelwetsuits.com/surf/index.php?area=products
