The sun is high, the cloud coverage non-existent and you need to keep your eyes shaded…you may a run for this visor. It’s great when the temperature is sweltering but you don’t want to keep your head covered. It’s a bio-washed, 100% cotton twill which allows for ease of cleaning from dirt and stains, has a Velcro closure at back for optimal fit, and a pre-curved visor to keep the sun at bay.
