radiator.netFremantle based, had mine for two full seasons and i would recommend to anyone.
It wouldn't replace a full wetsuit in winter but for those months either side of our season i use it almost exclusively.
I have a long arm top for sun protection, it does not hinder your upper body movement at all.
Fit and finish is excellent, very thin and easily goes under my wetsuit in a full on winter southerly gale.
If you just want a rashie then these would probably be too warm, but this is the time of year to have one, check out their range anyway.
