The cold water cap is ideal for wearing over neoprene bonnets, keeping your forehead warm and reducing overall heat loss (unlike silicon swim hats, it doesn’t pull neoprene bonnets off). Can also be used as a base layer with a normal hat. Worn alone they are good for adults and children who want to feel the water or find normal swim hats pull at their hair.
Made of silver polyurethene with elastic around the rim to keep them on, this cap is also chlorine resistant.
It is shown here worn over another hat that has earflaps.
