I used to be the one yelling, "the water's too warm!". Now, anything under 78 and I'm freezing. I'm thinking of buying a rash guard, but my local sporting goods stores don't carry them, so I have no idea how much drag they create. Would that keep me warm without creating drag? I can't stand the thought of a claustrophobic wet suit. I need something to keep my arms warm when swimming outdoors. Right now, the outdoor pools are barely 72 degrees.
