This is a high-quality cotton cap with three LED lights built into the brim with the black and silver Waterworks-Lamson logo. You may be familiar with a cap being marketed that has only forward-oriented LED lights. This hat has that feature, but also has downward-facing flood lights under the brim to illuminate the work space in front of your torso for tying on flies, etc. The under-brim flood lights are a patent-protected feature exclusive to WW-L in fly fishing. A button under the brim operates the lights. One click turns on all three lights; second click Vendor: Waterworks/Lamson
