Item#: ERGO-6630-Black Description

With the Chill-Its® 6630 Skull Cap, you get a cap that sits low on your head while offering excellent moisture management. The cap comes with a wide terry cloth sweatband that effectively absorbs sweat, keeping it away from your eyes, face, and glasses. The cap is made from Hi-Cool® moisture management performance fabric that is stretchy and can fit most head sizes. The cap is versatile and can be worn under a hard hat for added protection or on its own to provide sun-blocking protection.

This cap is available in multiple colors, including hi-vis lime for increased visibility in low-light environments.

The low-profile design fits comfortably under a hard hat or helmet and is great for construction workers, landscaping, roofing, or anybody working in the heat. Can also be used to reduce the risk of heat stress while mountain biking, motorcycling, gardening, hiking, playing sports and more.

Better than expected

It looks hot. It is not. It's like a sweat back built into a cooling cap.

To each their own.

Works well, but it felt like having a sweat-soaked bandana on by the afternoon. No sweat dripped into my eyes, but I didn't enjoy the feeling. Switched to the other style (#6632).

No complaints about this item. Perfect fit, sweat capture, and cool look. Totally recommend.
