I sailed through winter last year for the first time. Bought a cheapie full size from the dive/surf shop next to board crazy. Cost just over $100. Worked really well. Did have one freezing day mid winter at Cootharaba when I could of had a little more warmth - really needed something to keep the head warm
Probably saying - keep it simple - we are in Qld


Anything with long arms and legs is going to work
Outcome - sailed most weeks through winter and kept my sailing fitness up
