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.

Ergodyne 6630 Features:
  • MOISTURE-ABSORBENT – Wide, sweat absorbing terry cloth band lines the interior
  • PERFORMANCE KNIT FABRIC – Hi Cool® moisture management fabric

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).

It has been very hot in our area and the employees reviews are that the caps don't keep their head cool the way the chill it towels do.

My husband recently had radiation treatments and needs to keep his head covered at all times while outside for the rest of his life. These are perfect for him. They are lightweight and fit perfectly. Will be purchasing many more.

I liked the cap, bought thought it was a tight fit, for me. But very breathable and seemed to defer the sweat from running down into my eyes. I liked the product, Matthew G. MatthewsRoadServices

I bought this and the flame pattern for my husband, who has a very large head. They fit, he loves them. It's a win-win for me.

This cap works as a sweatband in summer, and a light warming cover in winter.

I like the product...but I wish it had the elastic band in the back like other caps... previous experience the headband area stretches out after several washes & is loose on my head.

I really liked the material colors pictured identical to the pic posted the only small problem was that it's a bit loose it's tight because of the material, it would be like a stretch tight fit but it works for what it's worth.

Good, but not great
3 stars out of 5 stars
I've been using the Chill-Its doo rags for cycling and really like the quality. I figured I'd go with the cap for a cleaner look. The doo rag has a very nice elastic and terry around the edge. And although the cap has a nice terry sweat catcher around the edge, there is no elastic to grip your head. Therefore, the cap is a very loose fit. Overall, it's still a nice product.

Skull Cap
4 stars out of 5 stars
I like it a lot except that it comes in one size. I have a fairly good size head and it's a little loose on me. I would prefer it to be a bit tighter. Someone with a small head might be disappointed.

Great cap

Bought these for my husband to wear to work and he loves them. Not only do they keep the sweat out of his eyes but they keep the dirt out also. Didn't find that they were cooling in any way though.
