I saw an Eddie Bauer ad for thermal swimsuits. Ted and I don’t swim in our pool after early or mid-October (depending on the weather) because, even with heated water, the air is really chilly when we leave the water. I don’t think an insulated swimsuit will help my exposed skin, so I’m pretty sure I won’t be one of the delighted swimsuit buyers who must get into that alpine lake for an icy polar plunge.
