Princeton Tec Sync LED Headlamp (300 Lumens, Black/Dark Gray), one Size

The Sync’s claim to fame? Simplicity. Intuitively cycle through modes using the large dial on the side and skip button pressing sequences - a must for tasks where you need to control modes on the fly, like running, and places where thick gloves are a must. The Sync’s max mode, Dual Beam (a combination of spot and flood) supplies a long throw of concentrated light and a smooth wide beam to illuminate the area around you.
