NO CONTEST AGAINST THE ZIPPED VARIETY
This top is great. No zips to do and undo and the neck fits nicely without being tight. I have long arms and the sleeves could be a little longer but that's just a niggle. It's warm enough for spring, summer and autumn bathing in northern european waters. Haven't had the opportunity to put it throught its paces to discover the close fit that I understand moulds to your body after several immersions.
