I've never thought of myself as warm-blooded, but I heat up quickly during a workout, relative to my normal temp. I'm usually freezing, until I start moving, and then I'm sweating buckets. Lycra caps were better, fog-wise, but I was going through one every other month because of the chlorination. I wish someone made a poly cap like my Endurance suits!

I hate to spend Garmin-type money to solve what seems like a simple, inexpensive problem...but it may come to that. Anyone use a simple multi-lap sports watch?
