Arizona Diamondbacks 2001 World Series New Era 59Fifty Fitted Hatin Black with Walnut Visor and Orange Under Brim.

Side Logo: Glow in the Dark

Glow in the dark only works when you charge the hat by exposing the hat in the light and then going into the darkness right away. It does NOT glow in the dark continuously or without charging.The glow in the dark effect fades fairly quickly.

How to makePatchGlow in the Dark:

Simply Expose Logo to Sunlight (or bright light) for at least one full minute to activate the green phosphorescent glow. The longer it is exposed, the longer and brighter the afterglow will be.
