Sun protection is all about coverage. So why do so many sun hats start so promising but stop so short? Wide brims are all well and good for shading our faces, but what about our shoulders and backs? That's what the folks at CoolHeads had in mind when they came up with this airy, soft terry cloth head covering that drapes over the head, forehead, shoulders and back. The CoolHeads sun hat looks like a cross between a towel and a hood, much like the traditional keffiya head scarf worn in the Middle East. An inner band system keeps the hat from flying off your head. CoolHeads come in bright, sun-reflecting white, with yellow, blue, green, black, or red cloth trim around the perimeter. You can tie the edges like a scarf, tuck the drape under your shirt, wrap a swatch over your face as an extra shield against sun and sand, or just let it all flow.

CoolHeads sun hats are $19.99 at www.getcoolheads.com.
